Removed Undervoltage Lockout (UVLO) Chip/Charge Enable Pin (CE) Packaging:
– TDFN-6 (2x2 mm) Temperature Range: -40°C to +85°C The MCP73830/L are highly integrated, Li-Ion battery
charge management controllers for use in spacelimited applications. The MCP73830/L devices provide
specific charge algorithms for single-cell Li-Ion/LiPolymer batteries to achieve optimal capacity and
safety in the shortest charging time possible. Along
with its small physical size, the low number of external
components makes the MCP73830/L ideally suitable
for portable applications.
The MCP73830L employs a constant current/constant
voltage charge algorithm. The minimum 20 mA …
