Low_voltage_power_disconnect

This circuit removes the power supply if the supply voltage drops below a certain value. As an example, the National Semiconductor LM199 precision reference has an on-chip heater that malfunctions with supply voltages below 9 V and it causes excessive device temperature. Using the values shown, the ICL8212 detects a supply voltage of 9 (or less) and turns off the supply to the LM199.
