XC61H
Series
Voltage Detector with Delay Circuit Built-In
ETR0212-002
■GENERAL
DESCRIPTION
The XC61H series is a highly accurate, low power consumption CMOS voltage detector with a delay circuit. Detect voltage is
accurate with minimal temperature drift. Output configurations are available in both CMOS and N-channel open drain.
Since the full delay circuit is built-in, an external delay-time capacitor is not necessary so that high density mounting is possible.
■APPLICATIONS
●
Microprocessor reset circuitry
●
System battery life and charge voltage monitors
●
Memory battery back-up circuits
●
Power-on reset circuits
●
Power failure detection
●
