This device is a dual high side switch for automotive applications which
incorporates a dual low side switch control feature. This device is designed to
monitor two low side switches for typical DC-motor control in an H-Bridge
configuration. It can be directly interfaced with a microcontroller for control and
diagnostic functions, is PWM capable and has a self-adjusted switching speed for
minimizing electromagnetic emission.
The High Side block incorporates two 15m
Rdson N-Channel power Mosfets
with senses and a control circuitry. Each output of this high side block is protected
against short to gnd and load shorts, and has over temperature detection with
hysteresis. It includes a current recopy feature for monitoring the load current. The
control circuitry also has an overvoltage detector which turns off the bridge and
protects the load in case of Vbat exceeding 28V.
The low side control block is able to drive 2 low sides switches in a H-bridge
configuration and protects them in case of short circuit. This, in combination with
the High side protection, fully protects the H-bridge from shorted loads, shorts to
Vbat and shorts to GND.
This device offers a very low quiescent current in standby mode.
