Voltage Detector with Watchdog Function and ON/OFF Control
AEC-Q100(Grade3) compliant

The XD6122 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 XD6122 series is internally pulled up to the VIN pin or pulled down to the VSS pin, these series can be used with the EN/ENB pin left open when the watchdog functions is used.
The detect voltages are 1.6V, 2.2V, 2.3V, 2.4V, 2.9V, 3.0V, 3.1V, 4.4V, 4.5V, 4.6V, 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

*TOREX’s automotive products (XD Series) are AEC-Q100 compliant.
