Description

The VN5772AK-E is a device formed by three
monolithic chips housed in a standard SO-28
package: a double high-side and two low-side
switches. The double high-side is made using
STMicroelectronics
while the low-side switches are fully protected
VIPower M0-5 OMNIFET III. This device is
suitable to drive a DC motor in a bridge
configuration as well as to be used as a quad
switch for any low-voltage application. The dual
high-side switches integrate built-in non latching
thermal shutdown with thermal hysteresis. An
output current limiter protects the device in
overload conditions. In the case of long overload
duration, the device limits the dissipated power to
a safe level-up to thermal shutdown intervention.
An analog current sense pin delivers a current
proportional to the load current (according to a
known ratio) and indicates overtemperature
shutdown of the relevant high-side switch through
a voltage flag.The low-side switches have built-in
non latching thermal shutdown with thermal
hysteresis, linear current limitation and
overvoltage clamping. In case of long overload
duration, the low-side switches limit the dissipated
power to a safe level up to the thermal shutdown
intervention. Fault feedback for overtemperature
shutdown of the low-side switch is indicated by
the relevant status pin.

1. To ensure long-term reliability under heavy overload or short-circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device is subjected to
abnormal conditions, this software must limit the duration and number of activation cycles.
