描述 Description

The device is a double channel high-side driver manufactured using STMicroelectronics proprietary VIPower® M0-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground.
Active VCC pin voltage clamp and load dump protection circuit protect the device against transients on the VCC pin. The device integrates an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is high impedance.
Output current limitation protects the device in overload condition. In case of long duration overload, the device limits the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the device to recover normal operation as soon as a fault condition disappears.
