TIMER

DESCRIPTION

The UTC UWD817 families are groups of high-precision, low

current consumption voltage detectors with manual reset input and

watchdog functions based on CMOS process. The series consist of

a reference voltage source, delay circuit, comparator, and output

driver. With the built-in delay circuit, the UTC UWD817 series do

not require any external components to output signals with release

delay time. The user can choose detect voltage thresholds.

The WDI pin in the UTC UWD817 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 V_IN

pin voltage level, the ICs can be used by leaving the manual reset

pin unconnected if the pin is unused.
