Table 1.
The VN920SP is a monolithic device designed in
STMicroelectronics VIPower M0-3 technology.
The VN920SP 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 over-load.
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 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.
