Description
The HM8203 is a highly advanced
complete constant-current/ constant voltage
linear charger for cell lithium-ion batteries. Its
package and low external component count
make the HM8203 ideally suited for
portable applications. The charge current can be
programmed externally with a s ingle resistor,
which may be programmed up to 0.9A.
HM8203 determines the charge mode by
detecting the battery voltage: Pre-charge,
constant current charging, constant voltage
charging. The charge current of 0pre-charging
and constant –current charging is adjustable.
The HM8203 is monitored by temperature
monitor during the constant-current and
constant-voltage charging. There are two LEDs
indicate the charge mode.
The HM8203 is available in the SOP-8L
package.
