The XC6101~XC6107, 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 ~ 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 ~ XC6115 series' ICs, 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 with the manual reset pin left unconnected if the pin is unused. 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 1.6sec. Seven release delay time 1 are available in a range from to 1.6sec.


Operating Voltage Range Detect Voltage Temperature Characteristics : +100ppm/OC (TYP.) Output Configuration : N-channel open drain, CMOS Watchdog Pin : Watchdog input If watchdog input maintains `H' or `L' within the watchdog timeout period, a reset signal is output to the RESET output pin Manual Reset Pin : When driven `H' to `L' level signal, the MRB pin voltage asserts forced reset on the output pin. Release Delay Time 25msec, 3.13msec (TYP.) can be selectable. Watchdog Timeout Period 50msec, 6.25msec (TYP.) can be selectable.

* 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 pin.
