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

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.

VN5772AK-E 3 Application information Application information Figure 26. Typical application schematic 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.
