SFT430C
SFT430C is USB Dedicated Charging Port Controller manufactured by SHOUDING.
Description
The SFT430C is a fast charge protocol controller for Hi Silicon Fast Charging Protocol (FCP) and Qualm® Quick Charge TM 2.0/3.0 (QC 2.0/3.0)
USB interface. The device can fast charging FCP or QC 2.0/3.0 powered device (PD). The protocol feature monitors USB D+/D- data line voltage or D- data line transmission and automatically adjusts output voltage of power bank and wall adaptor to optimize charge time.
SFT430C can support not only USB BC pliant devices, but also Apple / Samsung / HUAWEI devices and automatically detects whether a connected powered device is QC 2.0/3.0 or FCP capable before enabling output voltage adjustment. If a PD not pliant to QC 2.0/3.0 or FCP is detected the SFT430C disables output voltage adjustment to ensure safe operation with legacy 5 V only USB PDs.
The SFT430C is available in a space-saving SOT-23-6 package.
