MCP73853/55

USB Compatible Li-Ion/Li-Polymer

Charge Management Controllers

Features

Description

• Linear Charge Management Controllers

- Integrated Pass Transistor

The MCP7385X devices are highly advanced linear

charge management controllers for use in space-

limited, cost-sensitive applications. The MCP73853

combines high-accuracy constant-voltage, constant-

current regulation, cell preconditioning, cell temperature

monitoring, advanced safety timers, automatic charge

termination, internal current sensing, reverse blocking

protection and charge status and fault indication in a

space-saving 16-lead, 4 x 4 QFN package.

- Integrated Current Sense

- Reverse Blocking Protection

• High-Accuracy Preset Voltage Regulation: + 0.5%

• Two Selectable Voltage Regulation Options:

- 4.1V, 4.2V

• Programmable Charge Current

• USB Compatible Charge Current Settings

• Programmable Safety Charge Timers

• Preconditioning of Deeply Depleted Cells

• Automatic End-of-Charge Control

The MCP73855 employs all the features of the

MCP73853, with the exception of the cell temperature

monitor and one status output. The MCP73855 is

offered in a space-saving 10-lead, 3 x 3 DFN package.

The MCP73853 and MCP73855 are designed

specifically for USB applications, adhering to all the

specifications governing the USB power bus.

• Optional Continuous Cell Temperature

Monitoring:

- MCP73853

The MCP7385X devices provide two selectable voltage

regulation options (4.1V or 4.2V) for use with either

coke or graphite anodes.

• Charge Status Output for Direct LED Drive

• Fault Output for Direct LED Drive

- MCP73853

The MCP7385X devices provide complete, fully-

functional, charge management solutions, operating

with an input voltage range of 4.5V to 5.5V.

• Automatic Power-Down

• Thermal Regulation

• Temperature Range: -40°C to +85°C

• Packaging:

The MCP7385X devices are fully specified over the

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

- 16-Lead, 4x4 mm QFN (MCP73853)

- 10-Lead, 3x3 mm DFN (MCP73855)
