Description
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.
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.
The MCP73853 and MCP73855 are designed
specifically for USB applications, adhering to all the
specifications governing the USB power bus.
The MCP7385X devices provide two selectable
voltage regulation options (4.1V or 4.2V) for use with
either coke or graphite anodes.
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.
