STMicroelectronics VN1160-1

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. When a low load is detected (output current lower than Idf), flashing frequency is automatically doubled.
