IPS160HF, IPS161HF Datasheet Single channel high-side switches Features 8 V to 60 V operating voltage range Minimum output current limitation: 0.7 A (IPS161HF) or 2.5 A (IPS160HF) Short propagation delay at start-up Fast demagnetization of inductive load Non-dissipative short-circuit protection (cut-off) Programmable cut-off delay time using external capacitor Ground disconnection protection V disconnection protection CC Thermal shutdown protection Undervoltage lock-out Diagnostic signalization for: open load in off-state, cut-off and junction thermal shutdown Designed to meet IEC 61131-2 PowerSSO12 package Applications Programmable logic control Industrial PC peripheral input/output Numerical control machines Domotics Product status General power supply switch IPS160HF IPS161HF Description Product label The IPS160HF (Iout = 2.4 A) and IPS161HF (Iout = 0.6 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 m, 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 Product summary application and the load against electrical and thermal overstress. Furthermore, in IPS160HF IPS160HFTR order to minimize the power dissipation when the output is shorted, a low-dissipative Order code short-circuit protection (cut-off) is implemented to limit the output average current IPS161HF IPS161HFTR value and consequent device overheating. Cut-off delay time can be set by soldering Package PowerSSO12 an external capacitor or disabled by a resistor on pin 4 (CoD). Packing Tube Tape and reel The DIAG common diagnostic open drain pin reports the open load in off-state, cut-off (overload) and thermal shutdown.
