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

■GENERAL DESCRIPTION

The XC6121/XC6122/XC6123/XC6124 series are groups 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 XC6121/XC6122/XC6123/XC6124 series’ ICs do not require

any external components to output signals with release delay time. The output type is VDFL low when detected. With the

XC6121/XC6122/XC6123/XC6124 series’ ICs, 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, the ICs

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 100mV, using laser trimming technology. Six watchdog timeout period settings are available in a

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

■FEATURES

■APPLICATIONS

●Microprocessor watchdog monitoring

and reset circuits

Detect Voltage Range

: 1.6V ~ 5.0V, +2%

(100mV increments)

: VDFL x 5% (TYP.)

Hysteresis Width

Operating Voltage Range : 1.0V ~ 6.0V

●Memory battery backup circuits

●System power-on reset circuits

●Power failure detection

Detect Voltage Temperature

Characteristics

: +100ppm/^OC (TYP.)

Output Configuration

Watchdog Pin

: 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.

: 400ms, 200ms, 100ms, 50ms,

3.13ms (TYP.)

EN/ENB Pin

Release Delay Time

Watchdog Timeout Period : 1.6s, 800ms, 400ms, 200ms,

100ms, 50ms (TYP.)

: SOT-25, USP-6C
