Product overview

Description

The IPS2050H/HQ and IPS2050H-32/HQ-32 are dual high-side switch ICs able to drive capacitive, resistive or inductive loads with one side connected to ground.

The very low RDS-ON (≤ 50 mΩ up to TJ = 125 °C) makes the IC suitable for applications with up to 2.4 A (IPS2050H/HQ) or 5.6 A (IPS2050H-32/HQ-32) steady state operating current.

Each output channel is independently protected against junction over-temperature events by a junction temperature sensor, and a further temperature sensor is included to monitor case temperature, so an overheated output channel can only be turned back ON when the case temperature returns below the reset temperature.

The embedded per-channel overload protection circuit monitors the output current and, on triggering of the activation threshold (IPK-X), starts modulating the impedance of the output switch to limit the output current to ILIM-X, for both IC and load protection.

The IC offers two different sets of activation threshold and limitation levels (IPKH-X, ILIMH-X and IPKL-X, ILIML-X) for smart driving of capacitive loads (such as bulb lamps) and loads with initial peak current requirements.

The IC diagnostics is based on two FAULT pins (current source), one for each channel. Each FAULT pin is activated by an overload or an over-temperature event on the related channel.
