XC6101~XC6105, XC6111~XC6117 Series ETR0207 016 Voltage Detector (V =1.6V~5.0V) DF GENERAL DESCRIPTION The XC6101~XC6105, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with manual reset input and 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 XC6101 ~ XC6105, XC6111 ~ XC6117 series do not require any external components to output signals with release delay time. Moreover, with the manual reset function, reset can be asserted at any time. The ICs produce two types of output VDFL (low when detected) and VDFH (high when detected). With the XC6101 ~ XC6105, XC6111 ~ XC6115 series, the WD pin can be left open if the watchdog function is not used. Whenever the watchdog pin is opened, the internal counter clears before the watchdog timeout occurs. Since the manual reset pin is internally pulled up to the VIN pin voltage level, the ICs can be used by leaving the manual reset pin unconnected if the pin is unused. 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 6.25ms to 1.6s. Seven release delay times are available in a range from 3.13ms to 1.6s.
