Functional Pin Description

Pin No.

Pin Name

Pin Function

Enable Control Input (Active High). It must be connected to a logical voltage or

pulled up to VIN with a 100k resistor.

NTC

Input for an external NTC thermistor for battery temperature monitoring.

Control Signal of the Inner Loop of the Current Mode PWM. A capacitor of at

least 0.1F with a serial resistor to GND filters out the current ripple.

Charge Current Setting and System Loop Compensation Pin. Connect a

resistor from this pin to ground to set the charge current.

ISET

FBR

VFB

Negative Terminal of External Resistor Divider for Battery Voltage Feedback. A

200 resistor connect from FBR to GND.

Battery Voltage Feedback. Using an external resistor divider to set battery full

charge voltage.

Battery Voltage Sensing Input. A 10F or larger X5R ceramic capacitor is

recommended for filtering charge current ripple and stability purpose.

BATT

SNSL

SNSH

SNS

Negative Terminal for Sensing Charge Current.

Positive Terminal for Sensing Charge Current.

Input terminal for reversal current comparator.

To supply the current sense amplifier CAfor very low dropout condition. It must

be connected as shown in the typical application circuit or connected to VIN if

VIN is always larger than BATT by at least 3.6V.

VHH

Output of Internal 5V LDO. Connect a 1F ceramic capacitor from this pin to

GND for stability.

V5V

VIN

Input Power Supply. Connect a low ESR capacitor of 10F or higher from this

pin to ground for good bypass.

Output of low side driver.

Power Ground.

PGND

Switch Node. This pin switches between ground and VIN with high dv/dt rates.

Care needs to be taken in the PCB layout to keep this node from coupling to other

sensitive nodes.

Output of High-Side Driver with BOOT and SW as Floating Power and Return.

Bootstrap Supply for the High-Side Gate Driver and Control Circuitry. In normal

operation, V_BOOT≈ V_SW+ 5V.

BOOT

Input control pin for CCM of DCM mode selection. Tying MODE pin to V5V for

CCM mode selection and GND for DCM.

MODE

Flag to Indicate Charge Completion. It turns to logical high when the charge

current drops blew 20% of the setting charge current. A 0.1F capacitor from

STATUS to ground is needed to filter the sampled charge current ripple.

STATUS

Soft-Start Control Input. SS controls the soft-start time. Connect a capacitor

from SS pin to GND to set the soft-start time.

Negative Terminal to Sense Input Current. A filter is needed to filter out the

500kHz switching noise.

ACN

ACP

Positive Terminal to Sense Input Current.

ACDRV

Drive Signal for the Gate of Input Power PFET.

Signal Ground. The exposed pad must be soldered to a large PCB and

connected to GND for maximum thermal dissipation.

SGND
