1 Overview
The board comes pre-assembled with VND5T100AJ-E High Side driver. On board minimum
set of electrical components (as for device datasheet recommendation) is enabling the user
to directly connect the load, the power supply and the microcontroller without any additional
effort in external component design and connection. The VND5T100AJ-E is a device made
using STMicroelectronics
®
VIPower
®
technology, intended for driving resistive or inductive
loads with one side connected to ground. Active V
CC
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
CC
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.
