Functional Pin Description

Pin No.

Pin Name

Pin Function

WAKE

Wake-up impulse push pull output. If VIN or BAT plug in, the WAKE pin generates one

90ms-width high pulse to notify micro processor.

PVD1

Power output of CH1. To make CH1 stable, the power path from the PVD1 pin to its

output capacitors must be as short (

1mm is better) and wide as possible to reduce its

parasitic inductance. The output capacitor must be ceramic capacitor (

20F).

LX1

Switch node of CH1.

CHG2

2nd charger status indicator (Open-drain output).

FB7

Feedback input pin of CH7 in Step-up mode or current regulator mode

PVD7

Power output pin of CH7 in Step-up or power input Pin of CH7 in current regulator

mode.

LX7

Switch node of CH7 in step-up mode.

LX7 initial voltage determine CH7 operation mode.

CHG

Charger status indicator output (Open-drain output).

VO6

Power output of CH6.

PVD6

Power input of CH6.

FB4

Feedback voltage input of CH4.

SEQ

Power sequence selection for CH1 to CH4.

LX4

Switch node of CH4.

Enable control input of power converter unit.

PVD45

Power input of CH4 and CH5. To avoid the crosstalk between CH4 and CH5, the power

path from the PVD45 pin to its input capacitors must be as short (

1mm is better) and

wide as possible to reduce its parasitic inductance. The input capacitance must be

10F with low ESR.

LX5

Switch node of CH5.

INT

Interrupt indicator open-drain output. If events of NoBAT, THR, EOC, battery

temperature change (TS_METER), PGOOD, SAFE, VIN DPM, or charge type detection

finishing (CHGRUN) happen, the output INT goes low and the INT bit in I2C register

bank 0x9 is set to be “1”. After INT bit is written to be “0”, INT goes high.

VO5/FB5

Output voltage sense or feedback voltage input of CH5. The function is selected by I2C

PVD8

Power input of CH8.

SDA

Data signal of I2C interface.

SCL

Clock signal of I2C interface.

VO8

Power output of CH8.

FB2

Feedback voltage input of CH2.

VO2

Power output of CH2.

LX2B

Switch node B of CH2.

LX2A

Switch node A of CH2.

PVD2

Power input of CH2.
