Description
The VN770KP-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.
Table 1. Device summary
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.

Application recommendations VN770KP-E
3 Application recommendations
Figure 44. Application diagram bridge drivers
Most motor bridge drivers use a reverse battery protection diode (D) inside the supply rail.
This diode prevents a reverse current flow back to V
in case the bridge becomes
BATT
disabled via the logic inputs while motor inductance still carries energy. In order to prevent a
hazardous overvoltage at circuit supply terminal (V
), a blocking capacitor (C) is needed to
CC
limit the voltage overshoot. As basic orientation, 50µF per 1A load current is recommended.
As an alternative, a Zener protection (Z) is also suitable.
Even if a reverse polarity diode is not present, it is recommended to use a capacitor or
Zener at V
because a similar problem appears in case the supply terminal of the module
CC
has intermittent electrical contact to the battery or gets disconnected while the motor is
operating.
