ICL8211, ICL8212
Programmable
Voltage Detectors
Description
The Harris ICL8211/8212 are micropower bipolar monolithic integrated circuits intended primarily for precise
voltage detection and generation.
These circuits consist of an accurate
voltage reference, a comparator and a pair of output buffer/drivers.
Specifically, the ICL8211 provides a 7mA current limited output sink when the
voltage applied to the ‘THRESHOLD’ terminal is less than 1.
15V (the internal reference).
The ICL8212 requires a
voltage in excess of 1.
15V to switch its output on (no current limit).
Both devices have a low current output (HYSTERESIS) which is switched on for input...
