Package

Description

The VNQ500 is a monolithic device designed in
STMicroelectronics VIPower M0-3 technology,
intended for driving any kind of load with one side
connected to ground.

Active current limitation, combined with latched
thermal shutdown, protect the device against
overload.

In the case of over temperature of one channel
the relative I/O pin is pulled down.

The device automatically turns off in the case of
ground pin disconnection.

VNQ500 Electrical specifications

2 Electrical specifications

2.1 Absolute maximum ratings

Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality document.
