uc Description
rod The VN770K is a device formed by three
monolithic chips housed in a standard SO-28
P package: a double high side and two low side
te switches. Both the double high side and low side
le switches are made using STMicroelectronics
Obso VIPower™ M0-3 Technology.
SO-28
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 have built-in thermal
shutdown to protect the chips from over
temperature and current limiter blocks to protect
the device from short circuit. Status output is
provided to indicate open load in off and on-state
and over temperature.
The low side switches are two OMNIFET II types
(fully auto protected Power MOSFET in
VIPower™ technology). They have built-in
thermal shutdown, linear current limitation and
overvoltage clamping. Fault feedback for thermal
intervention can be detected by monitoring the
voltage at the input pin.
