Circuit provides hiccup-current limiting

Current-limit protection is an essential feature for power-supply systems. The three major types of current-limit-protection mechanisms are constant, foldback, and hiccup. Hiccup current limit performs the best of the three types; however, the implementat

Overload and reverse-current circuitry protects battery and load

protect against backward installation of batteries and other overcurrent-causing conditions

Short circuit beeper

Battery-protection circuit allows surges

circuit monitors two lithium-ion batteries and protects both of them against overcharging, overdischarging, and undervoltage

Circuit prevents deep discharge of batteries

to avoid the deep discharge that can destroy or shorten the life of a rechargeable battery, you must disconnect its load before the discharge is complete
