Overview
The FM2117L series is a high-precision overcharge and overdischarge protection circuit for single-cell rechargeable lithium batteries, integrating overvoltage charge protection, overvoltage discharge protection, and overcurrent discharge protection. Under normal operating conditions, the VDD pin voltage of the FM2117L is between the overvoltage charge protection threshold (VOC) and the overvoltage discharge protection threshold (VOD), and the VM detection pin voltage is between the charger detection voltage (VCHG) and the overcurrent discharge protection threshold (VEDI). In this state, both the COUT and DOUT pins output a high level, turning on the external charge control N-MOS transistor Q1 and discharge control N-MOS transistor Q2, respectively. This allows the battery to be charged via a charger or discharged through a load. The FM2117L performs overcharge/overdischarge protection by monitoring the VDD or VM pin voltage (relative to VSS). When a charge/discharge protection condition occurs, COUT/DOUT transitions from high to low, turning Q1/Q2 off and halting the charge/discharge process. Each protection state has a corresponding recovery condition; once the recovery condition is met, COUT/DOUT transitions from low to high, turning Q1/Q2 back on and returning to normal operation. A delay time is configured for each protection/recovery condition — the corresponding protection/recovery action is triggered only after the condition persists for the specified delay period. If the protection/recovery condition clears before the delay expires, the device will not enter the protection/recovery state.
