Description
The IPS1025H/HQ and IPS1025H-32/HQ-32 are single high-side switch ICs able to
drive capacitive, resistive or inductive loads with one side connected to ground.

IPS1025H
The very low RDS-ON (≤ 25 mΩ up to TJ = 125 °C) makes the IC suitable for the
applications with up to 2.4 A (IPS1025H/HQ) or 5.6 A (IPS1025H-32/HQ-32) steady
state operating current.
IPS1025H-32
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.
Product label
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
,
ILIMH and 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 FLT1 and FLT2 pins (both current source); activated
by respective overload or overtemperature events on the output channel.
