Pin Number
Name
Type
Description
F2, G1, G2
AC1
Input
AC power input 1. Connect AC1 to the CS capacitors and CS to the Rx coil. Connect the CD
capacitor from AC1 to AC2 (see Figure 2 and the application schematic in Figure 36). Due to
symmetry, the AC1 and AC2 connections are interchangeable.
F3
PDETB
Output
Open-drain, active-LOW. This pin is an output for indicating ping events are being received by
the Rx. Connect this pin to the application processor (AP) I/O voltage rail using an external
pull-up resistor.
F4, G4, G5
AC2
Input
AC power input 2. Connect this pin to the Rx coil and the CD capacitor (see Figure 2) Due to
symmetry, the AC1 and AC2 connections are interchangeable.)
F5
BST2
Output
Bootstrap capacitor for driving the high-side NFETs of the internal rectifier. Connect a 15nF
capacitor from AC2 to BST2.
G3
PDET_RC
Input
Ping-detect input pin for determining when PDETB will be de-asserted. This pin is used to notify
the AP if the Rx device is removed from the power transfer interface. Connect an RC time-delay
circuit designed to hold the voltage on this pin above VPDET_RC_IL between each Tx ping after
power transfer is completed (EOC).
