The BS45F3335 proximity sensing 2-Key touch Flash MCU which integrate a fully integrated active IR proximity sensing circuit, a receiving circuit and touch keys. It includes an integrated active IR proximity sensor circuit whose transmission power and receiving sensitivity can be controlled by application program and it also can be calibrated automatically when it uses with the integrated EEPROM.
In addition, the BS45F3335 includes a 1-channel H-bridge driver with a maximum motor peak current of 2.1A. A simple two input control pin structure is used to provide four control modes in active period: Forward, Reverse, Brake and Standby modes, and also control the H-bridge to enter/exit the sleep period.
The BS45F3335 is suitable for use in short and medium range detection applications, such as automatic soap dispensers, sensing alcohol sprayers, sensing trashcans, etc.
