Description
The FP6601 is a fast charge protocol controller
and follows Quick Charge 2.0 specification for
smart power bank application. The protocol
feature monitors USB D+/D- data line voltage,
and automatically adjusts output voltage of
power bank and wall adaptor to optimize charge
time.
FP6601 is a high performance solution for
fast-charging mechanism and it saves charging
time. It supports the full output voltage range of
either Class A.
FP6601 can support not only USB BC compliant
devices, but also Apple / Samsung devices and
automatically detects whether a connected
powered device (PD) is Quick Charge 2.0
capable before enabling output voltage
adjustment. If a PD not compliant to Quick
Charge 2.0 is detected the FP6601 disables
output voltage adjustment to ensure safe
operation with legacy 5 V only USB PDs.
The FP6601 is available in a space-saving
SOT-23-6 package.
