Preliminary

RT9501A/B

Advanced Lithium-Ion Linear Battery Charger

General Description

Features

^zFor Single Lithium-Ion or Lithium-Polymer Cell

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.

Battery Pack (4.1V or 4.2V)

^zA Few External Components are Required

^zPrecharge, Constant Current, Constant Voltage

Modes

^zBattery Temperature Monitor

^zCharge Status Indication

The RT9501 charges the battery in three modes,

precharge, constant current, constant voltage. If the

^zAutomatic Battery Recharge

^zCharge Termination Detect

battery voltage is below the precharge threshold V_O(MIN)

^zAuto Low Power Sleep Mode when VDD Power is

Removed

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.

^zMSOP-8 Package

Applications

z Digital Cameras

z PDAs

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.
