XC6121/XC6122

XC6123/XC6124^Series

ETR0209-011b

Voltage Detector with Watchdog Function and ON/OFF Control (V_DF=1.6V~5.0V)

■GENERAL DESCRIPTION

The XC6121/XC6122/XC6123/XC6124 series is a group of high-precision, low current consumption voltage detectors with

watchdog functions incorporating CMOS process technology. The series consist of a reference voltage source, delay circuit,

comparator, and output driver. With the built-in delay circuit, the series do not require any external components to output

signals with release delay time. The output type is VDFL low when detected. The EN/ENB pin can control ON and OFF of the

watchdog functions. By setting the EN/ENB pin to low or high level, the watchdog function can be OFF while the voltage

detector remains operation. Since the EN/ENB pin of the XC6122 and XC6124 series is internally pulled up to the VIN pin or

pulled down to the V_SSpin, these series can be used with the EN/ENB pin left open when the watchdog functions is used. The

detect voltages are internally fixed 1.6V ~ 5.0V in increments of 0.1V, using laser trimming technology. Six watchdog timeout

periods are available in a range from 50ms to 1.6s. Five release delay times are available in a range from 3.13ms to 400ms.

■APPLICATIONS

■FEATURES

Detect Voltage Range

: 1.6V ~ 5.0V, +2%

(0.1V increments)

: VDFL x 5% (TYP.)

: 1.0V ~ 6.0V

●System power-on reset circuits

●Power failure detection

: +100ppm/^OC (TYP.)

: N-channel open drain

: Watchdog input

If watchdog input maintains ‘H’ or

‘L’ within the watchdog timeout

period, a reset signal is output

from the RESETB pin.

: When the EN/ENB pin voltage is

set to low or high level, the

watchdog function is forced off.
