Description

The Intersil 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 out-

put 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

voltages in excess of 1.15V. The HYSTERESIS output may

be used to provide positive and noise free output switching

using a simple feedback network.
