XC6127 Series
Ultra Small Voltage Detector with High Precision Delay Circuit and Manual Reset Function
■GENERAL DESCRIPTION
XC6127 series is ultra small highly accurate voltage detector with delay circuit built-in.
The device includes a highly accurate reference voltage source, manufactured using CMOS process technology and laser
operation temperature range.
The release delay time periods are internally set in a range from 50ms to 800ms. Moreover, with the manual reset function, reset can be asserted at any time. The device is available in both CMOS and N-channel open drain output configurations. Also detect logic is available in both RESETB (Active Low) and RESET (Active High).
Ultra small package USPN-4 is ideally suited for small design of portable devices and high densely mounting applications.
The conventional packages SSOT-24,SOT-25 is also available for upper compatible replacements.
■APPLICATIONS
● Microprocessor logic reset circuitry
● System battery life and charge voltage monitors
● Memory battery back-up circuits
● Power-on reset circuits
● Power failure Detection
● Delay circuit
