MC33487 : Automotive Dual High-Side Driver

This device is a dual high side power switch dedicated for automotive applications. In comparison with mechanical relays, this device offers higher reliability as well as protection and diagnostic features. The device consists of two independent 25mOhm. Rdson switches in a surface mount package. It can be directly interfaced with a microcontroller for control and diagnostic functions and includes a current recopy function. The device is fully protected against overcurrents, short-circuits and incorporates an overtemperature shutdown. It can be directly and continuously supplied by the battery and offers a very low quiescent current in standby mode.

MC33487 Features

Junction Temperature Range from -40 to 150C

Operating Voltage Range from 8V to 40V

Reverse Battery protected up to -14V with no external components

Surface Mount Package, Thermally Enhanced

25mOhms max Rdson per Channel at 25C

vertemperature Protection with Hysteresis

Open Load Detection in On-State

Short-Circuit Protection

Loss of gnd, loss of Vbat protection
