GENERAL DESCRIPTION
The TC3827 is a battery charger controller for a single
cell Li-Ion battery. Using an external PMOS transistor, safe
and fast charging of a single Li-Ion cell is accomplished.
Features include over-current foldback, charge current
monitor, and charge status LED indicator output. An overall
system accuracy of 1% ensures that the cell capacity is fully
utilized without cycle life degradation. An external resistor
sets charge current.
The TC3827 operates with an input voltage range from
4.5V to 5.5V. It is specified over the ambient operating
temperature range of –20
°
C to +85
°
C and is available in a
space-saving 8-Pin MSOP.
