Description

E6, E7, E8,

E9

VOUT

O

Main LDO output pin. Connect 3 × 10

µF or more capacitors to ground.

F1

CMB

O

High-voltage open-drain modulation FET. Connect a capacitor from AC2 to CMB.

F2

VSENSE

I

Voltage sensing. Connect to sensing point as close as possible. Do not apply more than 5V during

operation.

F3

V1P8AP

I

Application processor (AP) power input. The V1P8AP pin should be connected directly to the

PMIC voltage rail. This pin must be powered to enable PDET function.

F4

LDO1P8

O

1.8V LDO for providing Internal power and ARM-M0 processor. Connect to a capacitor to GND.

F5, F6, F7,

F8, F9, G5,

G9

VRECT

O

Filter capacitor connection for the synchronous rectifier output. Connect to capacitors to GND.

G1

CM2

O

High-voltage open-drain modulation FET. Connect a capacitor from AC2 to CM2.

G2

ISP

I

Reverse external current sensing positive input. Connect to CPout if not used.

G3

TxEN

I

Tx mode active-high enable pin. Overrides /EN input pin if used. Connect to GND if not used.

G4

LDO5P0

O

Internal 5V LDO for chip power only. Connect to a capacitor to GND.

G6, H4, H5,

H6, J4

AC1

I/O

AC1 power input. Connect to RX LC tank (due to symmetry may connect to Rx coil or Resonance

Capacitor).

G7

BST2

O

Bootstrap capacitor for driving the high side N-MOSFET of the internal rectifier. Connect to a

capacitor from AC2 to BST2.

G8, H8, H9

AC2

I/O

AC2 power input. Connect to RX LC tank (due to symmetry may connect to Rx coil or Resonance

Capacitor).

H1

CMA

O

High-voltage open-drain modulation FET. Connect a capacitor from AC1 to CMA.

H2

ISN

I

Reverse current sensing negative input. Connect to CPout if not used.

H3

V5P0_AP

I

Application processor (AP) power input. The V5P0_AP pin can be directly connected to 5V

external power to replace LDO5P0 voltage to reduce device power consumption for high voltage

operation. Leave it floating if not used.

H7

BST1

O

Bootstrap capacitor for driving high side N-MOSFET of the internal rectifier. Connect a capacitor

from AC1 to BST1.

J1

CM1

O

High-voltage open-drain modulation FET. Connect a capacitor from AC1 to CM1.

J2

PCLAMP

I

High-voltage open-drain input for linear clamping during OVP events. Connect a resistor from this

pin to VRECT for > 5W operation. Short directly to VRECT for 5W or lower power applications.

J5, J6, J7,

J8, J9

PGND

GND

Power Ground. All PGND pins must be connected together with GND and CPGND externally.
