Overview
The TC5091B is a high-precision protection circuit for single-cell rechargeable lithium batteries with built-in MOSFETs, integrating overcharge protection, overdischarge protection, and overcurrent charge/discharge protection. Under normal conditions, the VDD voltage of TC5091B is between the overcharge protection threshold (VOC) and the overdischarge 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, TC5091B turns on the built-in N-MOS. The battery can then be charged via a charger or discharged through a load. TC5091B performs overcharge/overdischarge protection by monitoring the voltage at the VDD or VM pin (relative to GND). When a charge/discharge protection condition occurs, the built-in N-MOS switches from on to off, halting the charge/discharge process. TC5091B has corresponding recovery conditions for each protection state. Once the recovery condition is met, the built-in N-MOS switches from off to on, returning to normal operation. TC5091B incorporates a delay time for each protection/recovery condition. Protection or recovery is only triggered after the condition persists for the corresponding delay period. If the condition clears before the delay time elapses, the protection/recovery state is not entered. TC5091B operates at very low power consumption and is housed in a compact DFN-4L (1×1×0.5) package, making it highly suitable for rechargeable battery pack applications where space is limited.
