VN1160 - STMicroelectronics

VN1160 DIRECTION INDICATOR DRIVER

The VN1160, VN1160-1, VN1160T are a monolithic device made by using STMicroelectronics VIPower technology, intended for building a complete flashing unit for two wheel vehicles. The device is connected between the battery positive terminal (VCC pin) and a mechanical switch to the right and/or left bulbs. As soon as the series switch connects the OUT pin to t.

Features

1160 VN1160-1 VN1160T connected between the CEXT pin and the OUT pin stores energy for powering the device during the ON phase and sets the flashing frequency. When a low load is detected (output current lower than Idf), flashing frequency is automatically doubled.
