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.
