Features, Applications

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

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 VSS pin, the ICs can be used with the EN/ENB pin left open, when the watchdog functions is used. The detect voltages are internally fixed 5.0V in increments of 100mV, using laser trimming technology. Six watchdog timeout period settings are available in a range from to 1.6s. Five release delay time settings are available in a range from to 400ms.

APPLICATIONS

Microprocessor watchdog monitoring and reset circuits Memory battery backup circuits System power-on reset circuits Power failure detection

FEATURES

Hysteresis Width Operating Voltage Range Detect Voltage Temperature Characteristics : +100ppm/OC (TYP.) Output Configuration : N-channel open drain Watchdog Pin : Watchdog input If watchdog input maintains `H' or `L' within the watchdog timeout period, a reset signal is output from the RESETB pin. EN/ENB Pin : When the EN/ENB pin voltage is set to low or high level, the watchdog function is forced off. Release Delay Time 50ms, 3.13ms (TYP.) Watchdog Timeout Period 100ms, 50ms (TYP.) Package SOT-25, USP-6C

* The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS (No. 5) pin.

RESET OUTPUT SERIES XC6123 XC6124 VDFL (RESETB) N-channel open drain N-channel open drain N-channel open drain N-channel open drain VDFH (RESET) Available: VDFL x 5% (TYP.) HYSTERESIS EN/ENB PIN FUNCTION (EN/ENB INPUT LOGIC*, PULL-UP OR DOWN RESISTOR)

* EN input logic: The watchdog function turns on when the EN pin becomes high level. * ENB input logic: The watchdog function turns on when the ENB pin becomes low level.
