Description
The VN920SP-E is a monolithic device designed
in STMicroelectronics™ VIPower™ M0-3
technology. The VN920SP-E is intended for
driving any type of load with one side connected
to ground. The active VCC pin voltage clamp
protects the device against low energy spikes
(see ISO7637 transient compatibility table).
Active current limitation combined with thermal
shutdown and automatic restart protects the
device against overload.
The device integrates an analog current sense
output which delivers a current proportional to the
load current. The device automatically turns-off in
the case where the ground pin becomes
disconnected.

Absolute maximum ratings
Stressing the device above the rating listed in Table 3 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.
