Manufacturer:TI Description:The circuit described uses a low-power CMOS comparator to provide an LED visual indication of a low-battery condition, without excessive battery current drain. This is achieved by pulsing the LED at a low frequency and low duty cycle and conserving battery current in the OFF cycle by placing the comparator in shutdown. Equations and circuit analysis are included for determining duty cycle and comparator trip points. |
