ELM7C377142xA CMOS voltage detector, 2 channels, 18V operation, reset hold by ext.C
ELM7C377142xA is a 18V operation CMOS voltage detector for independent 2 lines power monitoring. It detects abnormalities such as power supply voltage interruptions or drops, and generates a reset signal. In addition to the 5V power supply line, VSB input can work for the another power supply line detection, and a reset signal is holded some period determined by an exterral capacitor.

- 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 ELM7C377142xA/ELM7C377342xA is new product developed in-house, the power consumption is a quarter of the conventional product.
