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 buff er/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
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.

NOTES:

1. The maximum output current of the ICL8211 is limited by design to 15mA under any operating conditions. The output voltage may be
sustained at any voltage up to +30V as long as the maximum power dissipation of the device is not exceeded.

2. The ma ximum outp ut curre nt of the ICL 8212 is not de fined. And sy stems usi ng th e ICL8 212 mu st ther efor e ensure that th e out put current
does not exceed 30mA and that the maximum power dissipation of the device is not exceeded.

3. Threshold Trip Voltage is 0.80V(min) to 1.30V(mas). At I

= 3mA.
