Working alongside the PMIC, this high-current inductor switches rapidly to step down the input voltage. If this inductor runs hot or exhibits cracked solder joints, the board will refuse to charge. 3. Battery Protection Circuit

If you find a shorted ceramic capacitor in the input filter stage, replace it with a capacitor rated for at least 16V or 25V, even though the rail only runs at 5V. This provides a safety margin against voltage spikes.

Bleeding resistors (usually 47 to 100 ohms) sit alongside switching transistors to dissipate excess energy from overcharged cells during the balancing phase. Charge and Discharge Switching Gate bm5291 ver 13 schematic verified

Grounding and PCB considerations

Check continuity across Pin 20 to Ground. Inject 1V low current to find overheating MLCC capacitors. Blown array slot inside the 74LS244 Octal Buffer.

Analog and RF (if applicable)

To support high peak currents without thermal runaway, the schematic features parallelized MOSFETs sharing the current load equally. Gate Resistors: Isolated resistors (typically Blown main fuse (F1) due to a short

If the thermistor circuit is broken or disconnected, the BM5291 will permanently lock out both charging and discharging paths as a safety precaution. Ensure the NTC resistor reads its nominal value (usually 10kΩ or 100kΩ at room temperature).
