The PUOLOP DW01A is a lithium-ion and lithium-polymer battery protection IC designed to protect single-cell battery packs against overcharging, over-discharging, overcurrent, and short-circuit conditions. Its compact SOT-23-6L package and low power consumption make it suitable for space-constrained battery-powered electronic devices.

The DW01A features a precise overcharge detection voltage of 4.3V ±50mV and an ultra-low quiescent current of just 3µA, helping minimize battery drain during standby. It also provides two levels of overcurrent detection and uses internal circuits to manage protection delay times, eliminating the need for external capacitors for this function.

With support for 0V battery charging and a wide operating temperature range, the PUOLOP DW01A is an effective solution for enhancing the safety, reliability, and service life of single-cell lithium battery packs.
