PIN DESCRIPTIONS

NAME

DESCRIPTION

OUT4

The Output of the LDO REG4. Bypass to GA with a 3.3μF high quality ceramic capacitor.

CHGIN

The Charger Input. Same function as pin A5 and pin B5.

VBAT

The Charger Output. Same function as pin B6 and pin B7.

INL6

The Input Node for the LDO REG6. Bypass to GA with a 1μF high quality ceramic capacitor.

nPBIN

The Push-Button Input. Drive nPBIN to GA through a 50kΩ resistor to enable the IC. When the IC is

enabled, driving nPBIN to GA through a 50kΩ resistor asserts the nIRQ to call interrupt service from

the host system, and driving nPBIN to GA directly asserts a manual reset procedure. nPBIN is

internally pulled up to VSYS through a 35kΩ resistor.

nPBSTAT

Active-Low Open-Drain Push-Button Status Output. nPBSTAT is asserted low whenever the

nPBIN is pushed, and is high-Z otherwise.

ODO3

The Open Drain Output 3. A current driver output with programmable output current. It could operate

in constant current mode, switch on/off mode or PWM mode. The maximum voltage is 6V for this pin.

OUT9

The Output of the LDO REG9. Bypass to GA with a 2.2μF high quality ceramic capacitor.

OUT8

The Output of the LDO REG8. Bypass to GA with a 3.3μF high quality ceramic capacitor.

OUT5

The Output of the LDO REG5. Bypass to GA with a 2.2μF high quality ceramic capacitor.

INL7

The Input Node for the LDO REG7. Bypass to GA with a 1μF high quality ceramic capacitor.

OUT6

The Output of the LDO REG6. Bypass to GA with a 3.3μF high quality ceramic capacitor.

OUT7

The Output of the LDO REG7. Bypass to GA with a 3.3μF high quality ceramic capacitor.

EN6

The Enable Input to the LDO REG6, Active High. This input takes effective only when this IC is

enabled.

EN9

The Enable Input to the LDO REG9, Active High. This input takes effective only when this IC is

enabled.

GLED

The Ground Node for ODO1, ODO2 and ODO3.

ODO2

The Open Drain Output 2. A current driver output with programmable output current. It could operate

in constant current mode, switch on/off mode or PWM mode. The maximum voltage is 6V for this pin.

OUT11

The Output of the LDO REG11. Bypass to GA with a 1μF high quality ceramic capacitor.

INL1011

The Input Node for the LDO REG10 and REG11. Bypass to GA with a 1μF high quality ceramic

capacitor.

OUT10

The Output of the LDO REG10. Bypass to GA with a 1.5μF high quality ceramic capacitor.

GP2

The Ground Path of the Step-down DC/DC REG2. Provide the direct ground return path between

the internal switch, the external storage capacitor and the input decoupling capacitor. Same function

as pin E7. Connect GA, GP1, GP2 and GP3 to a single point as close to the IC as possible.

GP2

The Ground Path of the Step-down DC/DC REG2. Same function as pin E6.
