125°C Operation 2-wire Interval Timer Convenience Timer S-35740 Series

Available Applications
Automotive ICs are categorized according to their application. The following symbols indicate the types of applications for which an IC can be used.
Safety critical components typified by engine, transmission, suspension and ABS, and EV/HEV/PHEV related equipment, etc.Meter, body, headlamp, ITS, etc.Accessory, car navigation, car audio system, etc.

The convenience timer is a CMOS timer IC which operates with low current consumption, and is suitable for the time management of the relative time.
The S-35740 Series outputs the fixed-cycle interrupt signal. The frequency and duty ratio of the fixed-cycle interrupt signal can be set freely by users via a 2-wire serial interface.
Moreover, the S-35740 Series has a built-in 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.

Caution: This product can be used in vehicle equipment and in-vehicle equipment. Before using the product in the purpose, contact to SII is indispensable.
