IPS161HF [STMicroelectronics]

The IPS160HF (Iout < 2.5 A) and IPS161HF (Iout < 0.7 A) are monolithic devices which can drive capacitive, resistive or inductive loads with one side connected to ground.

The 60 V operating range and Ron = 60 mΩ, combined with the extended diagnostic (Open Load, Over Load, Overtemperature) and the < 60 us propagation delay time at startup (enabling Class 3 for interface types C and D), make the IC suitable for applications implementing the proper architectures to address higher SIL levels.

The built-in overload and thermal shutdown protections guarantee the ICs, the application and the load against electrical and thermal overstress. Furthermore, in order to minimize the power dissipation when the output is shorted, a low-dissipative short-circuit protection (cut-off) is implemented to limit the output average current value and consequent device overheating. Cut-off delay time can be set by soldering an external capacitor or disabled by a resistor on pin 4 (CoD).

The DIAG common diagnostic open drain pin reports the open load in off-state, cut-off (overload) and thermal shutdown.
