PINOUT

PIN FUNCTIONS

Pin Name

PIN Number

ESOP8

ESSOP10 Description

6，7

Switch pin. Connect to external inductor.

BST

Internal charge pump boost pin.

STAT

Open-Drain Charge Status Output. When the battery is

charging, this pin is pulled low by an internal N-channel

MOSFET. When the HM5083 detects an under voltage lockout

condition, STAT is forced high impedance.

NTC

NTC (Negative Temperature Coefficient) Thermistor Input.

This pin senses the

Temperature of the battery pack and stops the charger when

the temperature is out of range. Connect to GND for disabling

this function.

VBAT

Battery pin.

SNS

Detecting pin of charge current.

LV5

5V LDO output PIN. Connect a minimum 1uF capacitor

between this PIN and GND.

VIN

Positive Supply Voltage Input. Decouple with a 10µF or larger

surface mounted

Ceramic capacitor.

GND

ePAD

Ground.

FBADJ

CV adjust PIN.

Connect resistor to GND increase CV voltage.

Connect resistor to VBAT decrease CV voltage.
