MCP73861/2/3/4

Advanced Single or Dual Cell, Fully Integrated Li-Ion /

Li-Polymer Charge Management Controllers

Features

Description

The MCP7386X family of devices are highly advanced

linear charge management controllers for use in space-

limited, cost-sensitive applications. The devices com-

bine high-accuracy, constant voltage and current regu-

lation, cell preconditioning, cell temperature monitoring,

advanced safety timers, automatic charge termination,

internal current sensing, reverse-blocking protection,

charge status and fault indication in either a space-

saving 16-pin, 4 x 4 QFN or 16-pin SOIC package. The

MCP7386X provides a complete, fully-functional, stand-

alone charge management solution with a minimum

number of external components.

• Linear Charge Management Controllers

- Integrated Pass Transistor

- Integrated Current Sense

- Reverse-Blocking Protection

• High-Accuracy Preset Voltage Regulation: + 0.5%

• Four Selectable Voltage Regulation Options:

- 4.1V, 4.2V – MCP73861/3

- 8.2V, 8.4V – MCP73862/4

• Programmable Charge Current: 1.2A Maximum

• Programmable Safety Charge Timers

• Preconditioning of Deeply Depleted Cells

• Automatic End-of-Charge Control

• Optional Continuous Cell Temperature Monitoring

• Charge Status Output for Direct LED Drive

• Fault Output for Direct LED Drive

• Automatic Power-Down

The MCP73861/3 is intended for applications utilizing

single-cell Lithium-Ion or Lithium-Polymer battery

packs, while the MCP73862/4 is intended for dual

series cell Lithium-Ion or Lithium-Polymer battery

packs. The MCP73861/3 have two selectable voltage-

regulation options available (4.1V and 4.2V), for use

with either coke or graphite anodes and operate with an

input voltage range of 4.5V to 12V. The MCP73862/4

have two selectable voltage-regulation options avail-

able (8.2V and 8.4V), for use with coke or graphite

anodes, and operate with an input voltage range of

8.7V to 12V.

• Thermal Regulation

• Temperature Range: -40°C to +85°C

• Packaging: 16-Pin, 4 x 4 QFN

16-Pin SOIC

Applications

The only difference between the MCP73861/2 and

MCP73863/4, respectively, is the function of the charge

status output (STAT1) when a charge cycle has been

completed. The MCP73861/2 flash the output, while

the MCP73863/4 turn the output off. Refer to

• Lithium-Ion/Lithium-Polymer Battery Chargers

• Personal Data Assistants (PDAs)

• Cellular Telephones

• Hand-Held Instruments

• Cradle Chargers

Section 5.2.1

“Charge

Status

Outputs

• Digital Cameras

• MP3 Players

(STAT1,STAT2)”.

The MCP7386X family of devices are fully specified

over the ambient temperature range of -40°C to +85°C.
