5W, QI WIRELESS POWER RECEIVER WITH INTEGRATED RECTIFIER AND LDO OUTPUT

P9025AC DATASHEET

11

NC1

NC

Not internally connected. This pin may be connected to others to facilitate routing or to improve

thermal performance.

12

OUT

O

Regulated 5.3V output voltage. Connect a 1μF in parallel with 4.7 μF capacitor between the pin

and ground.

13

NC2

NC

Not internally connected. This pin may be connected to others to facilitate routing or to improve

thermal performance.

14

EN

I

Active-low enable pin. The chip is suspended and placed in low-current (sleep) mode when this pin

is pulled high. This pin has internal pulldown resistor to Analog Ground (AGND).

15

TEOP

I

Active-high over-temperature input pin. When pulled high, the chip will disable the LDO output and

send a WPC End-of-Power packet with code 0x03 (over-temperature code). This pin has an

internal pull down resistor to ground.

16

NC3

NC

Not internally connected. This pin may be connected to others to facilitate routing or to improve

thermal performance.

17

CLAMP2

I

AC clamp input 2. Connect a 0.47uF capacitor from this pin to AC2 pin.

18

PGND2

-

Power ground for the AC clamp FETs.

19

CLAMP1

I

AC clamp input 1. Connect a 0.47uF capacitor from this pin to AC1 pin.

20

FOD2

I

FOD2 adjustment. A resistor between this pin and AGND sets the FOD offset value used in the

internal FOD calculation.

21

ACM1

I

AC Modulation input 1. Connect a 22nF capacitor from this pin to AC1 pin.

22

PGND1

-

Power ground for the full-wave rectifier.

23

ACM2

I

AC Modulation input 2. Connect a 22nF capacitor from this pin to AC2 pin.

24

NC4

NC

Not internally connected. This pin may be connected to others to facilitate routing or to improve

thermal performance.

25

FOD1

I

A resistor between this pin and Analog Ground selects the FOD compensation curve that is used

for the internal FOD calculation.

26

SDA

I/O

voltage rail. If not used, connect to ground.

27

SCL

I

rail. If not used, connect to ground.

28

AGND

-

Analog Ground connection.

29

VDD

O

Internal voltage supply. Connect a 1uF capacitor between this pin and Analog Ground. Do not

connect any external load to this pin.

30

AC2

I

AC2 input to the Internal full-wave rectifier.

31

PGND

-

Power ground for the full-wave rectifier.

32

STAT

O

Status output. A logic low state indicates that power is being transferred.
