CH217 Datasheet http://wch.cn USB Current limiting Power Distribution Switch Chip CH217 Datasheet Version: V1.0 http://wch.cn 1. Overview CH217 is a USB port power switch chip with adjustable current limiting threshold. The chip has integrated modules for over-current protection, over-temperature protection, and under-voltage protection, and supports programmable currents of up to 2.7A at 5V, which can limit the output current to protect the power supply system in the event of a short circuit at the VOUT output. The following is the internal block diagram of CH217 for reference only. VIN Current Sense VOUT UVLO EN# Current Limit ISET EN# Driver Deglitch OR FLAG# GND Thermal Sense 2. Feature l Built-in power switching tube, typical 70mΩ on-resistance.
