VPS2535H数据手册ST中文资料规格书

描述 Description

The VPS2535H is a monolithic device made using STMicroelectronics® VIPower® technology, 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.

The device integrates an analog current sense which delivers a current proportional to the load current.

Fault conditions such as overload, overtemperature or short to VCC are reported via the current sense pin.

Output current limitation protects the device in overload conditions. The device latches off in case of overload or thermal shutdown.

The device is reset by a low level pass on the fault reset standby pin.

A permanent low level on the inputs and on the fault reset standby pins disables all outputs and sets the device in standby mode.
