The GLF73614 is a family of IQSmartTM ultra efficient, full battery protection ICs with an accurate over charge/discharge voltage, shipping mode, over charge/discharge current, and short circuit protection for lithium-Ion/Polymer battery safety.
The overcharge and discharge voltage protections keep a rechargeable battery working within the desired safe operating condition. When the battery is charged past the over voltage detection level, the GLF73614 charging switch opens in a preset delay time. As the battery voltage decreases below the over discharge detection voltage level, the GLF73614 discharging switch is turned off immediately to cut off the battery power rail, consuming an ultra-low leakage current (ISD) to save the battery. In addition, when the load current reaches the ISC short circuit protection level, the GLF73614 is turned off and will maintain the off state to avoid any serious damage to system. The short circuit delay time avoids any false trigger which might open the switch.
