Smart low side power switch
Overview
Protective Functions
• Electrostatic discharge protection (ESD)
• Active clamp over voltage protection
• Thermal shutdown with latch behavior
• Over load and Short circuit protection
• Current limitation
Analog Fault Information
• Thermal shutdown
• Short to Battery
• Overload
Applications
• Designed for inductive and lamp loads in automotive and industrial applications.
• 12V and 24V applications
• All types of resistive, inductive and capacitive loads
• Replaces discrete circuits
Detailed Description
The device is able to switch all kind of resistive, inductive and capacitive loads, limited by EAS and maximum
current capabilities.
The BTS3046SDL offers ESD protection on the IN Pin which refers to the Source pin (Ground).
The overtemperature protection prevents the device from overheating due to overload and/or bad cooling
conditions. The temperature information is given by a temperature sensor in the power MOSFET. During thermal
shutdown the device sinks an increased input current at the IN pin to feedback the fault condition.
The BTS3046SDL has a thermal-latch function. The device will turn off and stay off, even after the measured
temperature has dropped below the thermal hysteresis. After cooling down the device can be switched on again
by toggling the IN pin.
The over voltage protection gets activated during load dump or inductive turn off conditions. The power MOSFET
is limiting the drain-source voltage, if it rises above the VDS(clamp).

5.1 Input Circuit
Figure 5 shows the input circuit of the BTS3046SDL. The Zener Diode ZD protects the input circuit against ESD
pulses. The internal circuitry is powered via the input pin. During normal operation the Input is connected to the
Gate of the power MOSFET. During fault condition the device sinks the current IIN(fault) to give the fault information
back to the driving circuit. The current handling capability of the driving circuit does not influence the device
behavior as long as the supply current IIN is supplied.

Protection Functions
6 Protection Functions
The device provides embedded protection functions. Integrated protection functions are designed to prevent IC
destruction under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal
operation.
6.1 Thermal Protection
The device is protected against over temperature due to overload and / or bad cooling conditions. To ensure this
a temperature sensor located in the Power MOSFET is used.
The BTS3046SDL has a thermal-latch function. The device will turn off and stay off, even after the measured
temperature has dropped below the thermal hysteresis. After cooling down the device can be switched on again
by toggling the IN pin.
The protective switch off can be reset by setting the input pin voltage to low. Then the internal logic is not supplied
anymore and the next time the voltage on the IN pin rises above the input threshold voltage, the device will switch
on, if the temperature is not above the over temperature threshold.

6.2 Overvoltage Protection
When switching off inductive loads with low-side switches, the Drain-Source voltage VD rises above battery
potential, because the inductance intends to continue driving the current.
Figure 13 Output Clamp
The BTS3046SDL is equipped with a voltage clamp mechanism that prevents the Drain-Source voltage to rise
above VD(Clamp) . See Figure 13 and Figure 14 for more details.
Figure 14 Switching an Inductance
While demagnetization of inductive loads, energy has to be dissipated in the BTS3046SDL.
This energy can be calculated by the following equation:
Following equation simplifies under assumption of RL = 0
Figure 16 shows the inductance / current combination the BTS3046SDL can handle.

6.3 Short Circuit Protection
The condition short circuit is an overload condition of the device. If the current reaches the limitation value of ID(lim)
the device limits the current and starts heating up. When the thermal shutdown temperature is reached, the device
turns off.
The time from the beginning of current limitation until the over temperature switch off depends strongly on the
cooling conditions.
The device sinks higher current on IN pin during the protective switch off and switches back ON after the IN
toggles.
Figure 16 shows this behavior.
