Description

The VND5T100AJ-E is a monolithic device made

using STMicroelectronics™ VIPower™

technology, intended for driving resistive or

inductive loads with one side connected to

ground. Active V

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.

Fault conditions such as overload,

overtemperature or short to V

are reported via

the current sense pin.

Output current limitation protects the device in

overload condition. 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 fault

reset standby pin disables all outputs and sets the

device in standby mode.

Application information 3.1.2 VND5T100AJ-E Solution 2: diode (DGND) in the ground line A resistor (RGND = 4.7 kshould be inserted in parallel to DGND if the device drives an inductive load. This small signal diode can be safely shared amongst several different HSDs. Also in this case, the presence of the ground network produces a shift (600 mV) in the input threshold and in the status output values, if the microprocessor ground is not common to the device ground.
