Pin No.
Pin Name
I/O
Pin Function
D3
BST1
P
Charge pump for gate drive. Connect a 22nF capacitor between
BST1 and CFH1.
D5
EN
DI
Device enable control pin. Pull high to disable device. I2C is still
available when EN pin is pull high.
D6
INT
DO
Open drain interrupt output. Connect to pull-up voltage via 10k
pull-up resistor. Normally high, when event happen, INT pin sends
a 256
s low pulse to system.
E1
WRX_OK
P
Push-pull structure. When WRX_IN over then WRX_INSERT level,
this pin will pull high to inform system.
E3, F3
CFH1
P
Flying capacitor positive node. Two 22
F capacitors must be
connected to CFL1 and CFH1 and placed as close as possible to
the device. These pins must be connected together on the PCB.
E5, F5
CFL1
P
Flying capacitor negative node. Two 22
F capacitors must be
connected to CFL1 and CFH1 and placed as close as possible to
the device. These pins must be connected together on the PCB.
F1
SYNC
AIO
Push-pull structure. Master device's sync pin connect to slave
device's sync pin. Let pin floating in standalone mode.
