Table 1. Device summary

PENTAWATT
Description
PENTAWATT
in-line
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 V
pin voltage
CC
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.
