Preliminary
LINEAR INTEGRATED CIRCUIT
MONOLITHIC IC 82XX SERIES
DESCRIPTION
The normal operation of the UTC
82XX
is that while the power
is turned on or interrupted, detect power supply voltage and then
reset the system accurately.
The internal circuits of the UTC
82XX
include a built-in fixed
delay time generating circuit. With a counter timer using an
analog/digital hybrid circuit, the UTC
82XX
as new low reset type
system reset ICs expands the delay time series.
These ICs can be used in a variety of CPU systems and other
logic systems.
FEATURES
* Internal Fixed Delay Time Setting by Counter Timer
* Grate Delay Time Temperature Characteristics:±800ppm/°C
* Operating Limit Voltage as 0.65V(Typ.)
* Hysteresis Voltage Provided: 50mV(Typ.)
