The SFT430C

1

Description

is a fast charge protocol controller

for HiSilicon Fast Charging Protocol (FCP) and

Qualcomm

®

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.

can support not only USB BC compliant

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 compliant to QC 2.0/3.0 or

FCP is detected the

disables output

voltage adjustment to ensure safe operation with

legacy 5 V only USB PDs.

The

is available in a space-saving

SOT-23-6 package.
