VND5E012AY-E中文资料Double channel high side driver with analog current sense for automotive applications数据手册ST规格书

描述 Description

The VND5E012AY-E is a device made using STMicroelectronics®VIPower®M0-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes.
This device integrates an analog current sense which delivers a current proportional to the load current when CS_DIS high leads the current sense pin in high impedance.
Fault conditions such as overload, overtemperature or open-load are reported via the current sense pin
Output current limitation protects the device in overload condition. In case of long overload duration, the device limits the dissipated power to safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the device to recover normal operation as soon as fault condition disappears.
