Description
The BTN8980TA is an integrated high current half bridge for motor drive applications. It is part of the NovalithIC™
family containing one p-channel highside MOSFET and one n-channel lowside MOSFET with an integrated driver
IC in one package. Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing
EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs,
diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature,
undervoltage, overcurrent and short circuit.
The BTN8980TA provides a cost optimized solution for protected high current PWM motor drives with very low
board space consumption.

Block Diagram
2 Block Diagram
The BTN8980TA is part of the NovalithIC™ family containing three separate chips in one package: One p-channel
highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming an integrated high
current half-bridge. All three chips are mounted on one common lead frame, using the chip on chip and chip by
chip technology. The power switches utilize vertical MOS technologies to ensure optimum on state resistance.
Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing EMI. Interfacing
to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with
current sense, slew rate adjustment, dead time generation and protection against overtemperature, undervoltage,
overcurrent and short circuit. The BTN8980TA can be combined with other BTN8980TA to form H-bridge and 3-
phase drive configurations.

5.2 Power Stages
The power stages of the BTN8980TA consist of a p-channel vertical DMOS transistor for the high side switch and
a n-channel vertical DMOS transistor for the low side switch. All protection and diagnostic functions are located in
a separate top chip. Both switches allow active freewheeling and thus minimizing power dissipation during PWM
control.
The on state resistance RON is dependent on the supply voltage VS as well as on the junction temperature Tj. The
typical on state resistance characteristics are shown in Figure 6.

Figure 8 Definition of switching times low side (Rload to VS)
Due to the timing differences for the rising and the falling edge there will be a slight difference between the length
of the input pulse and the length of the output pulse. It can be calculated using the following formulas:
•
Δ
tHS = (tdr(HS) + 0.5 tr(HS)) - (tdf(HS) + 0.5 tf(HS))
•
Δ
tLS = (tdf(LS) + 0.5 tf(LS)) - (tdr(LS) + 0.5 tr(LS)).

5.3 Protection Functions
The device provides integrated protection functions. These are designed to prevent IC destruction under fault
conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range.
Protection functions are not to be used for continuous or repetitive operation, with the exception of the current
limitation (Chapter 5.3.3). In case of overtemperature the BTN8980TA will apply the slew rate determined by the
connected slew rate resistor. In current limitation mode the highest slew rate possible will be applied independent
of the connected slew rate resistor. Overtemperature and overcurrent are indicated by a fault current IIS(LIM) at the
IS pin as described in the paragraph “Status Flag Diagnosis with Current Sense Capability” on Page 19 and
Figure 12.
5.3.1 Undervoltage Shut Down
To avoid uncontrolled motion of the driven motor at low voltages the device shuts off (output is tri-state), if the
supply voltage drops below the switch-off voltage VUV(OFF). The IC becomes active again with a hysteresis VUV(HY)
if the supply voltage rises above the switch-on voltage VUV(ON).
5.3.2 Overtemperature Protection
The BTN8980TA is protected against overtemperature by an integrated temperature sensor. Overtemperature
leads to a shut down of both output stages. This state is latched until the device is reset by a low signal with a
minimum length of treset at the INH pin, provided that its temperature has decreased at least the thermal hysteresis
ΔT in the meantime.
Repetitive use of the overtemperature protection impacts lifetime.
5.3.3 Current Limitation
The current in the bridge is measured in both switches. As soon as the current in forward direction in one switch
(high side or low side) is reaching the limit ICLx, this switch is deactivated and the other switch is activated for tCLS.
During that time all changes at the IN pin are ignored. However, the INH pin can still be used to switch both
MOSFETs off. After tCLS the switches return to their initial setting. The error signal at the IS pin is reset after 2 * tCLS.
Unintentional triggering of the current limitation by short current spikes (e.g. inflicted by EMI coming from the
motor) is suppressed by internal filter circuitry. Due to thresholds and reaction delay times of the filter circuitry the
effective current limitation level ICLx depends on the slew rate of the load current dI/dt as shown in Figure 10.

compared to driving the MOSFET in linear mode. Therefore it is possible to use the current limitation for a short
time without exceeding the maximum allowed junction temperature (e.g. for limiting the inrush current during motor
start up). However, the regular use of the current limitation is allowed as long as the specified maximum junction
temperature is not exceeded. Exceeding this temperature can reduce the lifetime of the device.
5.3.4 Short Circuit Protection
The device provides embedded protection functions against
• output short circuit to ground
• output short circuit to supply voltage
• short circuit of load
The short circuit protection is realized by the previously described current limitation in combination with the over-
temperature shut down of the device.

5.4 Control and Diagnostics
5.4.1 Input Circuit
The control inputs IN and INH consist of TTL/CMOS compatible schmitt triggers with hysteresis which control the
integrated gate drivers for the MOSFETs. Setting the INH pin to high enables the device. In this condition one of
the two power switches is switched on depending on the status of the IN pin. To deactivate both switches, the INH
pin has to be set to low. No external driver is needed. The BTN8980TA can be interfaced directly to a
microcontroller, as long as the maximum ratings in Chapter 4.1 are not exceeded.
5.4.2 Dead Time Generation
In bridge applications it has to be assured that the highside and lowside MOSFET are not conducting at the same
time, connecting directly the battery voltage to GND. This is assured by a circuit in the driver IC, generating a so
called dead time between switching off one MOSFET and switching on the other. The dead time generated in the
driver IC is automatically adjusted to the selected slew rate.
5.4.3 Adjustable Slew Rate
In order to optimize electromagnetic emission, the switching speed of the MOSFETss is adjustable by an external
resistor. The slew rate pin SR allows the user to optimize the balance between emission and power dissipation
within his own application by connecting an external resistor RSR to GND.
5.4.4 Status Flag Diagnosis with Current Sense Capability
The sense pin IS is used as a combined current sense and error flag output.
In normal operation (current sense mode), a current source is connected to the status pin, which delivers a current
proportional to the forward load current flowing through the active high side switch. The sense current can be
calculated out of the load current by the following equation:
(1)
The other way around, the load current can be calculated out of the sense current by following equation:
(2)
The differential current sense ratio dkilis is defined by:
(3)
If the high side drain current is zero (ISD(HS) = 0A) the offset current IIS = IIS(offset) still will be driven.
The external resistor RIS determines the voltage per IS output current. The voltage can be calculated by
VIS =RIS .IIS.
In case of a fault condition the status output is connected to a current source which is independent of the load
current and provides IIS(lim). The maximum voltage at the IS pin is determined by the choice of the external resistor
and the supply voltage. In case of current limitation the IIS(lim) is activated for 2 * tCLS.

Application Information
6 Application Information
Note: The following information is given as a hint for the implementation of the device only and shall not be
regarded as a description or warranty of a certain functionality, condition or quality of the device.
6.1 Application Circuit
Figure 15 Application Circuit: H-Bridge with two BTN8980TA
Note: This is a simplified example of an application circuit. The function must be verified in the real application.
6.2 Layout Considerations
Due to the fast switching times for high currents, special care has to be taken to the PCB layout. Stray inductances
have to be minimized in the power bridge design as it is necessary in all switched high power bridges. The
BTN8980TA has no separate pin for power ground and logic ground. Therefore it is recommended to assure that
the offset between the ground connection of the slew rate resistor, the current sense resistor and ground pin of
the device (GND / pin 1) is minimized. If the BTN8980TA is used in a H-bridge or B6 bridge design, the voltage
offset between the GND pins of the different devices should be small as well.
Due to the fast switching behavior of the device in current limitation mode a low ESR electrolytic capacitor Cs from
VS to GND is necessary. This prevents destructive voltage peaks and drops on VS. This is needed for both PWM
and non PWM controlled applications. To assure efficiency of Cs and CSC the stray inductance must be low.
Therefore the capacitors must be placed very close to the device pins. The value of the capacitors must be verified
in the real application, taking care for low ripple and transients at the Vs pin of the BTN8980TA.
The digital inputs need to be protected from excess currents (e.g. caused by induced voltage spikes) by series
resistors greater than 7kΩ.

Note: This is a simplified example of an application circuit. The function must be verified in the real application.
6.3 PWM Control
For the selection of the max. PWM frequency the choosen rise/fall-time and the requirements on the duty cycle
have to be taken into account. We recommend a PWM-period at least 10 times the rise-time.
Example:
Rise-time = fall-time = 4µs.
=> T-PWM = 10 * 4µs = 40µs.
=> f-PWM = 25kHz.
The min. and max. value of the duty cycle (PWM ON to OFF percentage) is determined by the real fall time plus
the real rise time. In this example a duty cycle make sense from approximately 20% to 80%.
If a wider duty cycle range is needed, the PWM frequency could be decreased and/or the rise/fall-time could be
accelerated.
