XD6124

XD6121/XD6122 XD6123/XD6124 Series ETR02040-007a Voltage Detector with Watchdog Function and ON/OFF Control ☆AEC-Q100 Grade3 ■GENERAL DESCRIPTION The XD6121/XD6122/XD6123/XD6124 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 and XD6124 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. ■APPLICATIONS ● Microprocessor watchdog monitoring and reset circuits ●Memory battery backup circuits ●System power-on reset circuits ●Power failure detection ■FEATURES Detect Voltage Range (Standard) : 1.6V, 2.2V, 2.3V, 2.4V, 2.9V, 3.0V,...
