Overview
The FH7071 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 conditions, the VDD pin voltage of the FH7071 series 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 FH7071 series performs overcharge/overdischarge protection by monitoring the voltage at the VDD or VM pin (relative to the VSS pin). When a charge/discharge protection condition occurs, COUT/DOUT transitions from high to low, switching Q1/Q2 from on to off, thereby stopping the charge/discharge process. The FH7071 series has corresponding recovery conditions for each protection state. Once a recovery condition is met, COUT/DOUT transitions from low to high, switching Q1/Q2 from off to on, returning to normal operation. A delay time is defined for each protection/recovery condition — the corresponding protection/recovery action is only triggered after the condition persists for the specified duration. If the protection/recovery condition clears before the delay time elapses, the device will not enter the protection/recovery state.
