Single channel high side driver
PowerSSO-24
Description
The VN920PEP-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 V
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.

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.
