SL1054
Advanced Lithium-Ion Linear Battery Charger
General Description
SL1054 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.
SL1054 charges the battery in three modes, precharge, constant current, constant voltage. If
the battery voltage is below the precharge threshold VO(MIN), the SL1054 precharges the battery
with a lower conditioning current. After precharge, the SL1054 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. SL1054 inhibits charge until the temperature is within the range defined by users.
