Pin Description

Pin No.

Pin Name

Function

1, 3, 5

C1, C2, C3

LED drive terminals (Open collector outputs)

2, 4, 6

E1, E2, E3

These terminals are used to set the LED drive currents.

7, 8

Rc, Cc

These terminals are used to set the oscillating frequency of the internal clocks.

9

Dchg IN

This is an input terminal used to detect the current which is used for the discharge

current feedback.

10

Dchg OUT

This is the drive terminal for the transistor mounted externally for discharge purposes.

11

Chg SW

This is the SW drive terminal used for charging battery.

27, 12

GND1, GND2

These are grounding terminals. (GND1 is for logic and GND2 is for analog.)

13

Batt SW

This is used to detect mounting of battery. (It is pulled up internally)

14

Dchg SW

This is used to detect the discharge SW. (It is pulled up internally)

15

Adpt SW

This is used to detect adapter SW. (It is pulled up internally)

16, 17

Test1, Test2

These are Test Mode set-up terminal. (It is pulled up internally)

20

Batt +

This terminal is connected to the + terminal of the battery.

21

Batt –

This terminal is connected to the – terminal of the battery.

23

Batt T

This terminal is connected to the temperature detecting terminal of the battery.

22

Vref2

This is the voltage reference terminal for temperature detection.

24

P.C

This terminal is connected to the photo-coupler used for feedback.

25

This terminal is used to monitor the output voltage.

26, 30

CP1, CP2

This terminal is used to make connection with capacitor(s) and resistor(s) which are

used for phase compensation.

29

This terminal is used to detect the charging current or output current.

31

PCS IN

This is an input terminal used for photo-coupler short.

32

PCS OUT

This terminal goes "H" when over-current is detected.

33

OCSET

This terminal is used to set the over-current detection value when the adapter mode

is used.

34, 35

Iset1, Iset2

These are used to set the charging current. (Iset1 is for quick charge and Iset2 is for

the trickle charge.)

36

Vref1

This terminal is sets the standard voltage for over-current set-up value and the

charge current set-up.
