Description

The IPS1025HF and 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 R_DS-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.

Product label

The very low R_DS-ON(≤ 25 mΩ up to T_J= 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 (I_PK), starts modulating the impedance of the

output switch to limit the output current to I_LIM, for both IC and load protection.

The IC offers two different sets of activation threshold and limitation levels (I_PKH

I_LIMHand I_PKL, I_LIML) 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.
