MCP73861/2

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

Li-Polymer Charge Management Controllers

Features

Description

• Linear Charge Management Controllers

- Integrated Pass Transistor

The MCP7386X family of devices are highly advanced

linear charge management controllers for use in space-

limited, cost-sensitive applications. The MCP73861 and

MCP73862 combine high-accuracy constant voltage,

constant current regulation, cell preconditioning, cell

temperature monitoring, advanced safety timers, auto-

matic charge termination, internal current sensing,

reverse-blocking protection, and charge status and fault

indication in a space-saving 16-pin, 4 x 4 QFN package.

The MCP7386X provides a complete, fully-functional,

stand-alone charge management solution with a

minimum number of external components.

- Integrated Current Sense

- Reverse-Blocking Protection

• High-Accuracy Preset Voltage Regulation: + 0.5%

• Four Selectable Voltage Regulation Options:

- 4.1V, 4.2V - MCP73861

- 8.2V, 8.4V - MCP73862

• 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 is targeted for applicatioins utilizing

single-cell Lithium-Ion or Lithium-Polymer battery

packs, while the MCP73862 is targeted for dual series

cell Lithium-Ion or Lithium-Polymer battery packs. The

MCP73861 has two selectable voltage-regulation

options available (4.1V and 4.2V), for use with either

coke or graphite anodes, and operates with an input

voltage range of 4.5V to 12V. The MCP73862 has two

selectable voltage-regulation options available (8.2V

and 8.4V), for use with coke or graphite anodes, and

operates 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

Applications

The MCP7386X family of devices are fully specified

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

• Lithium-Ion/Lithium-Polymer Battery Chargers

• Personal Data Assistants

• Cellular Telephones
