XC6105

The XC6105, XC6111~XC6117 series are groups of high-precision, low current consumption voltage detectors with manual reset input function 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 XC6105, XC6111 ~ XC6117 series' ICs 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' ICs, the WD pin can be left open if the watchdog function is not used.

Whenever the watchdog pin of XC6105 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 with the manual reset pin left unconnected if the pin is unused. The detect voltages are internally fixed 1.6V ~ 5.0V in increments of 100mV, using laser trimming technology. Six watchdog timeout period settings of XC6105 are available in a range from 6.25msec to 1.6sec. Seven release delay time 1 are available in a range from 3.13msec to 1.6sec.
