Battery voltage monitor
Philips' IC TypeTEA1041T is intended primarily for monitoring the voltage of 1.8-4.0 V batteries. Internal trigger and timing Iogic prevent a circuit from reacting to brief breaks in the supply voltage caused by pulses on the load current. One or two LEDs may be used to indicate when the voltage drops below a preset level.
