 General features
– Inrush current management by active
power limitation on the high-side switches
– Very low standby current
– Very low electromagnetic susceptibility
– Compliant with European directive
2002/95/EC
 Protections
– High-side drivers under voltage shutdown
– Overvoltage clamp
– Output current limitation
– High and low-side overtemperature
shutdown
– Short-circuit protection
– ESD protection
 Diagnostic functions
– Proportional load current sense
– Thermal shutdown indication on both the
high and low-side switches
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® VIPower® M0-5 technology,
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.

Mostly motor bridge drivers use a reverse battery protection diode (D) inside supply rail.
This diode prevents a reverse current flow back to Vbatt in case the bridge gets disabled via
the logic inputs while motor inductance still carries energy. In order to prevent a hazardous
overvoltage at circuit supply terminal (VCC), a blocking capacitor (C) is needed to limit the
voltage overshoot. As basic orientation, 50 μF per 1 A load current is recommended. In
alternative, also a Zener protection (Z) is suitable.
Even if a reverse polarity diode is not present, it is recommended to use a capacitor or zener
at VCC because a similar problem appears in case supply terminal of the module has
intermittent electrical contact to the battery or gets disconnected while motor is operating.
