Description
The VN920-E 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 VCC pin voltage
clamp protects the device against low energy
spikes (see ISO7637 transient compatibility able).
Active current limitation combined with thermal
shutdown and automatic restart protect the device
against overload. The device integrates an analog
current sense output which delivers a current
proportional to the load current. Device
automatically turns off in case of ground pin
disconnection.

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.

1. To ensure long term reliability under heavy over-load or short circuit conditions, protection and related
diagnostic signals must be used together with a proper software strategy. If the device operates under
abnormal conditions this software must limit the duration and number of activation cycles.
