Functions

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.

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

7, 8 Rc, Cc clocks.

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

9 Dchg IN 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, 2 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)

23

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

Test1, 2 These are Test Mode set-up terminal.(It is pulled up internally)

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

Batt –

Batt T

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

This terminal is connected to the temperature detecting terminal of the

battery.

Vref2 This is the voltage reference terminal for temperature detection.

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

V DET This terminal is used to monitor the output voltage.

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

CP1, CP2 which are used for phase compensation.

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

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

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

OC SET This terminal is used to set the over-current detection value when the

adapter mode is used.

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

Iset1, 2 Iset2 is for the trickle charge.)

Vref1

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

and the charge current set-up.
