DW01 Single-Cell Lithium-Ion Battery Protection IC for Overcharge and Overdischarge Safety
The DW01 is a widely used single-cell lithium-ion / lithium-polymer battery protection IC, designed to safeguard rechargeable batteries against overcharge, overdischarge, overcurrent, and short-circuit conditions. It works in combination with external dual MOSFETs to form a complete battery protection circuit, commonly found in 18650 cells, power banks, and compact battery packs.
This protection IC continuously monitors battery voltage and current, disconnecting the load or charger automatically when abnormal conditions are detected. With low power consumption, compact footprint, and reliable threshold accuracy, the DW01 is ideal for portable electronics where battery safety, longevity, and cost efficiency are critical. The device is fully compatible with USB charger ICs such as TP4056 and AP5056, making it a standard choice in single-cell charging modules.
