1 General description

The PCA9485 is a highly integrated switched-capacitor converter with an embedded OVPFET and dual external

FET controls, targeted to provide the quadruple output current for the fast charging applications with a 1-cell

battery. The device works in 4:1 switching operation with an extremely high efficiency (around 96.8 %, at VOUT =

4.5 V, IOUT = 8 A), in 1:4, 2:1 and 1:2 switching operation or in 1:1 mode with forward and reverse direction.

Absolute maximum voltage for each VUSB, VWPC, VIN, VOUT, and VUSB/VWPC input is designed to support

up to 35 V. VIN input supports up to 27 V with the pre-bias enabled for USB VBUS/wireless receiver output.

VOUT input is designed to support up to 7 V with the pre-bias enabled for a 1-cell battery application.

The device provides multiple safety schemes such as OC (overcurrent), RC (Reverse-Current), OV

(overvoltage), UV (Under-Voltage), switching pin short, thermal shutdown, and others.

The PCA9485 also has leader-follower function built in that allows two PCA9485 devices to be used seamlessly

in handheld applications.

The device features all the functions with an I2C interface, with up to 1 MHz speed.
