DESCRIPTION

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 the bulbs, the device

begins to turn on/off with a 50 duty cycle.

An external low voltage capacitor (220mF, 10V)

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.
