SD59D25S
SOC chip applied to the multi-in-one solution for power TOOLS

   SD59D25S is a highly integrated protocol and power control chip applied to the multi-in-one solution for power tools. It integrates 1 USB port (Type-C) and is compatible with fast-charging protocols such as PD3.2 AVS, PPS, QC4.0+, FCP, SCP, AFC, BC1.2, APPLE, VOOC, and UFCS. It features 4 channels of PWM driver control with configurable dead time to enable bidirectional Buck-Boost switching power conversion. An internal high-precision ADC enables lithium battery charge and discharge management.

    With its rich set of functions, the SD59D25S provides a complete solution for fast charging in power tools. The simple system periphery significantly reduces BOM costs.
