MCP73113/4
Single-Cell Li-Ion/Li-Polymer Battery Charge Management
Controller with Input Overvoltage Protection
Features: Description: Complete Linear Charge Management Controller:
-Integrated Input Overvoltage Protection
-Integrated Pass Transistor
-Integrated Current Sense
-Integrated Reverse Discharge Protection Constant Current/Constant Voltage Operation
with Thermal Regulation The MCP73113/4 are highly integrated Li-Ion battery
charge management controllers for use in
space-limited and cost-sensitive applications. The
MCP73113/4 devices provide specific charge
algorithms for Li-Ion/Li-Polymer batteries to achieve
optimal capacity and safety in the shortest charging
time possible. Along with their small physical size, the
low number of external components make the
MCP73113/4 ideally suitable for portable applications.
The absolute maximum voltage, up to 18V, allows the
use of MCP73113/4 in harsh environments, such as
low cost wall wart or voltage spikes from plug/unplug. 4.15V Undervoltage Lockout (UVLO) 18V Absolute Maximum Input with OVP:
-6.5V (MCP73113)
-5.8V (MCP73114) High Accuracy Preset Voltage Regulation Through
Full Temperature Range (-5В°C to +55В°C): +0.5% Battery Charge Voltage Options: …
