XC6804 Series
ETR25008-002
One Cell Li-ion/Li-polymer Linear Charger IC with Battery Temperature Detection
GENERAL DESCRIPTION
The XC6804 is a Constant-Voltage (CV) and Constant-Current (CC) type charging IC for linear charging of single-cell Li-ion
batteries and Li-polymer batteries. The basic charging cycle consists of trickle charge mode followed by main charge mode.
This IC supports temperature control based on JEITA, making it possible to safely charge Li-ion batteries and Li-polymer
batteries by controlling the CV charge voltage and CC charge current according to the temperature. By connecting a resistor to
the charge status output pin, it is possible to check the charge condition via the charge status output (CSO) pin voltage. The IC
is housed in the small SOP-8FD or USP-6EL(Under Development) package with high heat dissipation, and a charge circuit can
be configured using a minimum of external components.

*To increase mounting strength and heat dissipation of the USP-6EL, it is recommended that the heat sink be mounted by soldering using the
reference pattern layout and reference metal mask. To use the electric potential of the heat sink, connect to the VSS pin (Pin # 2).
