XC6129
Series
Voltage Detector with Delay Time Adjustable
ETR0222-002
■GENERAL
DESCRIPTION
XC6129 series is an ultra small highly accurate voltage detector with external capacitor type delay function.
The device includes a highly accurate reference voltage source, manufactured using CMOS process and laser trimming
technology, it maintains low power consumption and high accuracy. The device includes the built-in delay circuit. A release
delay time or detect delay time can be set freely by connecting an external delay capacitor to Cd pin.
There are two kinds of the output configuration for the XC6129 such as CMOS or N-channel open drain. The series has a
function to prevent an indefinite operation. Therefore, when the input pin voltage is under minimum operating voltage,
the function controls an output pin voltage in the indefinite operation less than 0.4V (MAX.). Also, the series allows a choice of
an output logic when detection; therefore, it is suitable for various electric devices using Microcontrollers.
Ultra small package USPN-4 and SSOT-24 (standard) are ideally suited for small design of portable devices and high
densely mounting applications.
