Simple and Easy Power-OK Indicator Detects Under- and Over-Voltage


要約: Undervoltage/overvoltage (UV/OV) indicators, also called Power-OK (POK) indicators, can notify portable-equipment users when the battery voltage is too low or the battery is being overcharged. POK indicators usually control an external FET to block the supply voltage during such faults. They're also useful as shown, as simple indicators without the FET.
