Preliminary
RT9501A/B
Advanced Lithium-Ion Linear Battery Charger
General Description
The RT9501 is a single Lithium-Ion or Lithium-Polymer
cell linear battery charger which is designed for compact
and cost-sensitive handheld devices. It combines charge
status indication, charge termination, battery temperature
monitoring, and high accuracy current and voltage
regulation in a MSOP-8 package.
The RT9501 charges the battery in three modes,
precharge, constant current, constant voltage. If the
battery voltage is below the precharge threshold V
O(MIN)
,
the RT9501 precharges the battery with a lower
conditioning current. After precharge, the RT9501 applies
a constant current to the battery. An external sense-
resister sets the charge current. The constant voltage
mode continues until the battery reaches the regulation
voltage.
The battery temperature is continuously measured by an
external thermistor through the TS pin. The RT9501
inhibits charge until the temperature is within the range
defined by users.
