IPS1025HFTR General Description

The IPS1025HF and IPS1025HFQ are single high-side switch ICs able to drive capacitive, resistive or inductive loads with one side connected to ground.The 60 V operating range and RDS-ON= 12 mΩ (typ.), combined with the extended diagnostic (Over Load, Over-temperature) 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 very low RDS-ON(≤ 25 m? up to TJ= 125 °C) makes the IC suitable for the applications with up to 2.4 A steady state operating current.The output channel is protected against junction over-temperature events by a junction temperature sensor, and a further temperature sensor is included to monitor case temperature, so the overheated output channel can only be turned back ON when the case temperature returns below the reset temperature.The embedded overload protection circuit monitors the output current and, on triggering of the activation threshold (IPK), starts modulating the impedance of the output switch to limit the output current to ILIM, for both IC and load protection.The IC offers two different sets of activation threshold and limitation levels (IPKH, ILIMHand IPKL, ILIML) for smart driving of capacitive loads (such as bulb lamps) and loads with initial peak current requirements.The IC diagnostics is based on FLT1and FLT2pins (both current source); activated by respective overload or overtemperature events on the output channel.
