Description
EV-VNQ5027AK provides you an easy way to
connect ST’s surface mounted VIPower
®
drivers
into your existing prototype circuitry. This
evaluation board comes pre-assembled with
VNQ5027AK-E high-side driver.
The VNQ5027AK-E is a monolitic device made
using STMicroelectronics
®
VIPower technology. It
is 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 (according to a known ratio) when
CS_DIS is driven low or left open. When CS_DIS
is driven high, the CURRENT SENSE pin is in a
high impedance condition. 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.
