LC709501F
Power Bank Controller with
USB Type-C & Quick Charge™ 3.0
for 1-Cell Li-Ion and Li-Poly Battery
Overview
LC709501F is a Lithium ion switching charger controller for Power
Bank. This device has all functions to control Power Bank application.
It can control Type-C port control IC and includes Quick Charge 3.0
HVDCP. The built-in switching controller can output from 5 V up to 12
V for Quick Charge. The high power output for USB Type-C and Quick
Charge is possible with appropriate external MOSFETs.

USB Support
This device allows 2 or 3 USB ports for Power Bank application.
The USB port functions will vary by writing of prepared
Firmware. The Firmware is distinguished by the Firmware
number which is called FW01, FW02, FW05, and FW06.
FW01 (Planning)
Micro-B input, Type-A output 2-ch, Quick Charge 3.0
HVDCP, Boost auto start-up, External Boost-IC,
Portable device communication. Displays Power Bank battery
information on smartphones. USB 2.0 Full Speed Host
Controller.
FW02 (Released)
Micro-B input, Type-A output 2-ch, Quick Charge 3.0
HVDCP, Boost auto start-up, External Boost-IC.
FW05 (Released)
Type-C DRP, Type-A output, Quick Charge 3.0 HVDCP,
Boost auto start-up, External Boost-IC.
FW06 (Planning)
Supports USB-PD
The Relationship between the Firmware and the USB port
functions is shown in Table 4 and Figures 6, 7, and 8. USB1+/
port of FW01/FW02 is a power sink. This port is an input for
Buck charge. And it contains functions of BC1.2 and divided
mode. USB2+/ port is a power source. This port is an output for
Boost charge. Portable device communication and Quick Charge
3.0 are only enabled in USB2+/ port. Another power source
that is Type-A (2) is boosted by an external Boost-IC. This
device runs the Boost-IC when it detects the plug insertion to
Type-A (2).
USB1+/- port of FW05 is fully TCPCI compliant. It is capable of
controlling BC1.2 as well up to external port control IC (for USB
Type-C implementations). The port can be dual-role, upward-
facing, or downward-facing.
The firmware can be downloaded from the homepage of ON
Semiconductor. Please refer to an application note for the writing
tool.
Buck charge mode: Built-in battery charging via USB.
Boost charge mode: Charging the device from built-in battery via USB.
