The interval timer IC allows for intermittent system operation by inputting a signal to the system at fixed periods of time.
The S-35740 outputs an interval signal (fixed-cycle interrupt signal). The frequency and duty ratio of the interval signal (fixed-cycle interrupt signal) can be set freely by users via a 2-wire serial interface.
The S-35740 has a 24-bit timer. For example, users can obtain the cumulative energization time of the system since the timer performs a count-up action every second.
