SL1053
Advanced Lithium-Ion Linear Battery Charger
General Description
SL1053 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 SOP-8 package.
SL1053 charges the battery in three modes, precharge, constant current, constant voltage. If
the battery voltage is below the precharge threshold VO(MIN), the SL1053 precharges the battery
with a lower conditioning current. After precharge, the SL1053 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
The battery temperature is continuously measured by an external thermistor through the TS
pin. SL1053 inhibits charge until the temperature is within the range defined by users.
