Description

The VN771KP-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

Table 1. Device summary

™

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.

Note: 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.
