IPS2050H - Dual high-side switch IC


High efficiency, high-side switch with extended diagnostics and smart driving for capacitive loads

The IPS2050H is a dual high-side switch IC 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 / 5.6 A 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.
