Description

The IPS160H is a monolithic device which can drive capacitive, resistive or inductive

loads with one side connected to ground; it is specifically designed to match safety

integrity level (SIL) applications.

Built-in thermal shutdown protects the chip against overtemperature and short-circuit.

In order to minimize the power dissipation when the output is shorted, a non-

dissipative short-circuit protection (cut-off) is implemented, it limits both the output

average current value and, consequently, the device overheating. The DIAG common

diagnostic pin reports the thermal shutdown, open load in off-state and cut-off.

Cut-off delay time can be programmed by an external capacitor.

6Protection and diagnostic

The IC integrates several protections to ease the design of a robust application.

6.1 Undervoltage lock-out

The device turns off if the supply voltage falls below the turn-off threshold (VUV(off)). Normal operation restarts

after VCC exceeds the turn-on threshold (VUV(on)). Turn-on and turn-off thresholds are defined in Table 4. Supply.

6.2 Overtemperature

The output stage turns off when its internal junction temperature (TJ) exceeds the shutdown threshold TJSD.

Normal operation restarts when TJ comes back below the reset threshold (TJSD - TJHYST), see Table 8. Protection

and diagnostic. The internal fault signal is set when the channel is off due to thermal protection and it is reset

when the junction triggers the reset threshold. This same behavior is reported on DIAG pin.

6.3 Cut-off

The IC can limit the output current at the power stage by its embedded output current limitation circuit.

This circuit continuously monitor the output current and, when load is increasing, at the triggering of its activation

threshold (3.8A TYP) it starts limiting to ILIM limitation level (See Protection and diagnostic): while current

limitation is active the IC enters an high dissipation status.

The IPS160H implements the cut-off feature which limits the duration of the current limitation condition.

The duration of the current limitation condition (Tcoff) can be set by a capacitor (CCoD) placed between CoD and

GND pins. The design rule for CCoD is:

tcoff[us] +/- 35% = 50 x Ccod[nF]

The drift of +/-35% is guaranteed in the range of 10 nF < Ccod < 100 nF; lower capacitance than 10 nF can be

used.

If ILIM threshold is triggered, the output stage remains in the current limitation condition (IOUT = ILIM) no longer

than tcoff. If tcoff elapses, the output stage turns off and restarts after the tres restart time.

Thermal shutdown protection has higher priority than cut-off:

• IC is forced off if TJSD is triggered before tcoff elapses

• if TJSD is triggered, IC is maintained off even after the tres has elapsed and until the TJ decreases below

TJSD-TJHYST

Protection and diagnostic

DS10907 - Rev 6 page 10/26

The fault condition is reported on the DIAG pin. The internal cut-off flag signal is latched at output switch-off and

released after the time tres, the same behavior is reported on DIAG pin.

The status of the DIAG is independent on the IN pin status.

If CoD pin is connected to GND through 1 kΩ resistor (cut-off feature disabled), when the output channel triggers

the limitation threshold, it remains on, in current limitation condition, until the input becomes LOW or the thermal

protection threshold is triggered.

In case of low ambient temperature conditions (TAMB < -20 °C) and high supply voltage (VCC > 36 V) the cut-off

function needs activating in order to avoid IC permanent damages. The following table reports the suggested cut-

off delay for the different operating voltage.

6.4 Open load in off-state

The IPS160H provides the open load detection feature which detects if the load is disconnected from the OUT

pin. This feature can be activated by a resistor (RPU) between OUT and VCC pins.

RLED

In case of wire break and during the OFF state (IN = low), the output voltage VOUT rises according to the the

partitioning between the external pull-up resistor and the internal resistance of the IC (RI = 115 kΩ).

The effect of the LED (if any) on the output pin has to be considered as well. In case of wire break and during the

ON state (IN = high), the output voltage VOUT is pulled up to VCC by the low resistive integrated switch. If the load

is not connected, in order to guarantee the correct open load signalization it must result:

VOUT > VOLoff(max.)

Referring to the circuit in figure 6:

VOUT =VCC − RPU ×IPU =VCC − RPU ×IRI +ILED +IRL (1)

therefore:

IPS160H

Open load in off-state

DS10907 - Rev 6 page 11/26

RPU <VCC min − VOLoff max

VOLoff max

RI+VOLoff max − VLED

RLED

(2)

If the load is connected, in order to avoid any false signalization of the open load, it must result as follows:

VOUT < VOLoff(min)

By taking into account the circuit in figure 6:

VOUT =VCC − RPU ×IPU =VCC − RPU ×VOUT

RI+VOUT − VLED

RLED +VOUT

RL(3)

so:

RPU >VCC max − VOLoff min

VOLoff min

RI+VOLoff min − VLED

RLED +VOLoff min

(4)

The fault condition is reported on the DIAG pin and the fault reset occurs when load is reconnected.

If the channel is switched on by IN pin, the fault condition is no longer detected.

When inductive load is driven, some ringing of the output voltage may be observed at the end of the

demagnetization. In fact, the load is completely demagnetized when ILOAD = 0 A and the OUT pin remains floating

until next turn-on. In order to avoid a fake signalization of the open load event driving inductive loads, the open

load signal is masked for tBKT. So, the open load is reported on the DIAG pin with a delay of tBKT and if the open

load event is triggered for more than tBKT.

6.5 VCC disconnection protection

The IC is protected despite the VCC disconnection event. This event is intended as the disconnection of the VCC

wire from the application board, see figure below. When this condition happens, the IC continues working

normally until the voltage on the VCC pin is ≥ VUVOFF. Once the VUVOFF is triggered, the output channel is turned

off independently on the input status. In case of inductive load, if the VCC is disconnected while the output channel

is still active, the IC allows the discharge of the energy still stored in the inductor through the integrated power

switch.

6.6 GND disconnection protection

GND disconnection is intended as the disconnection event of the application ground, see figure below. When this

event happens, the IC continues working normally until the voltage between VCC and GND pins of the IC results ≥

VUVOFF. The voltage on GND pin of the IC rises up to the supply rail voltage level. In case of GND disconnection

event, a current (ILGND) flows through OUT pin. Table 7. Logic inputs reports IOUT = ILGND for the worst case of

GND disconnection event in case of output shorted to ground.

7Active VDS clamp

Active clamp is also known as fast demagnetization of inductive loads or fast current decay. When a high-side

driver turns off an inductance, an undervoltage is detected on output.

The OUT pin is pulled down to Vdemag. The conduction state is modulated by an internal circuitry in order to keep

the OUT pin voltage at about Vdemag until the load energy has been dissipated. The energy is dissipated both in

IC internal switch and in load resistance.

The demagnetization of inductive load causes a huge electrical and thermal stress to the IC. The curve plotted

below shows the maximum demagnetization energy that the IC can support in a single demagnetization pulse

with VCC = 24 V and TAMB = 125 °C. If higher demagnetization energy is required then an external free-wheeling

Schottky diode has to be connected between OUT (cathode) and GND (anode) pins. Note that in this case the

fast demagnetization is inhibited.
