Features
Description
• High Accuracy Voltage Sensing and Generation
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.
• Internal Reference 1.15V Typical
• Low Sensitivity to Supply Voltage and Temperature
Variations
• Wide Supply Voltage Range Typ. 1.8V to 30V
• Essentially Constant Supply Current Over Full Supply
Voltage Range
• Easy to Set Hysteresis Voltage Range
• Defined Output Current Limit ICL8211
• High Output Current Capability ICL8212
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.
