DESCRIPTION
The VN772K-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. Both the double high side and low side
switches are made using |STMicroelectronics
VIPower™ M0-3 Technology. 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.
Figure 1. Package
The high side switches have built-in thermal
shutdown to protect the chips from
overtemperature 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 overtemperature. The low side switches are
two OMNIFET II types (fully autoprotected 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.
