BA3170 General Description

The BA3170 is a trickle-charge IC developed for two-cell, lithium-ion batteries.The IC includes a charge control circuit, a charge output transistor, and an LED driver for showing the charging status.

BA3170 Features

1) Output voltage can be varied using an external resistor.
2) The output pin is PNP output with low saturation voltage.
3) Built-in output current limiting circuit protects batteries
from excessive current, and prevents destruction
of the IC due to output shorts.
The initial charge current is set to a low value (the current
limit pin voltage can be used to vary the current limit value).
4) Pulse charging at over 99% of the final voltage.
5) Built-in over-discharge battery return circuit.
6) Built-in charge fault protection circuit.
7) Built-in over-voltage battery operation circuit.
8) Built-in LED output for charge display (two outputs).
9) 12-pin power package provides large power dissipation in a compact package.
10) Temperature protection circuit prevents thermal destruction of the IC.

BA3170 Typical Application

Lithium-ion (two cell) battery chargers, and charging circuits
