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, 4x4 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  
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, 3x3 DFN package.  
• USB Compatible Charge Current Settings  
• Programmable Safety Charge Timers  
• Preconditioning of Deeply Depleted Cells  
• Automatic End-of-Charge Control  
• Optional Continuous Cell Temperature Monitoring  
The MCP73853 and MCP73855 are designed  
specifically for USB applications, adhering to all the  
specifications governing the USB power bus.  
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  
These devices have complete and fully-functional,  
charge management solutions, operating with an input  
voltage range of 4.5V to 5.5V. These are fully specified  
over the ambient temperature range of -40°C to +85°C.  
MCP73853  
• Automatic Power-Down  
• Thermal Regulation  
Temperature Range: -40°C to +85°C
