ELM7C3793xxxxA CMOS voltage detector with dual input watchdog timer
ELM7C3793 series is an integrated circuit to monitor power voltage; it incorporates a watchdog timer. A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for system operation diagnosis can provide a fail-safe function for various application systems. The standard detection voltages are 3.0V, 3.7V, 4.2V and 4.5V; ELM7C3793 series can also be made as semi-custom IC within the range of 1.6V to 5.0V by 0.1V step.

- This product is alternative parts that “C” company have discontinued a selling.Please contact us once, if you have trouble with parts procurement.
- In addition, since ELM7C3771xxxA/ELM7C377342xA is new product developed in-house, the power consumption is a quarter of the conventional product.
