DIO58561/B

5~100mA, Single Cell Charger

Features

Descriptions

The DIO58561/B is a complete constant-current /

constant voltage linear charger for single cell

Lithium-Ion batteries. No external sense resistor is

needed, and no blocking diode is required due to

the internal MOSFET architecture. Thermal

feedback regulates the charge current to limit the

die temperature during high power operation or

high ambient temperature. The charge voltage is

fixed at 4.2V for DIO58561 and 4.35V for

DIO58561B, and the charge current and the

terminal current can be programmed externally

with resistors. The input voltage is up to 36V.



Broad Programmable Charging Current:

5~100mA



Over-Temperature Protection

Under Voltage Lockout Protection

Reverse current protection between BAT and

GND pins



Programmable Charge Termination Current

Maximum Voltage Power Input: 36V

Automatic Recharge Threshold:

DIO58561: 4.05V

DIO58561B: 4.2V



Final Float Voltage:

DIO58561: 4.2V

When the input supply (wall adapter or USB

supply) is removed, the DIO58561/B automatically

enters a low current state, dropping the battery

drain current to less than 2.0µA.

DIO58561B: 4.35V



Charge Status Output Pin

Trickle Charge Threshold:

DIO58561: 2.5V

The DIO58561/B is available in a small package

with DFN2*2-8. Standard product is Pb-Free.

DIO58561B: 2.6V



Soft-Start Limits Inrush Current

Over Voltage Lockout Protection

Package: DFN2*2-8

Applications



Wireless phone

MP3/MP4 Player

Bluetooth device
