CHARACTERISTICS
Parameters
All voltages referenced to ground.
A 1 kΩ external resistor may be required in some applications for proper operation of the microprocessor
reset control circuit when using the TC1279. V
Operating current is specified with the open-drain output in the active (“ON”) condition.
Operating current is specified with the open-drain output in the non-active (“OFF”) condition.
