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.

Analog current sense pins, they deliver a current proportional to the load current
In case of latch-off for overtemperature/overcurrent condition, a low pulse on the
FR_Stby pin is needed to reset the channel.
The device enters in standby mode if all inputs and the FR_Stby pin are low.
