USB Compatible
Lithium-Ion Battery Charger
with Thermal Regulation
The LTC
4053 is a standalone linear charger for lithium-
ion batteries that can be powered directly from a USB port.
The IC contains an on-chip power MOSFET and eliminates
the need for an external sense resistor and blocking diode.
Thermal regulation automatically adjusts charge current
to limit die temperature during high power or high ambient
temperature conditions. This feature protects the end
product and the LTC4053 from thermal stress while the IC
charges the battery at maximum rate without interruption.
The charge current and charge time can be set externally
with a single resistor and capacitor, respectively. When
the input supply (wall adapter or USB supply) is removed,
the LTC4053 automatically enters a low current sleep
mode, dropping the battery drain current to less than 5
A.
The LTC4053 also includes NTC temperature sensing,
C/10 detection circuitry, AC present logic, low battery
charge conditioning (trickle charging) and shutdown (25
A
supply current).
The LTC4053 is available in 10-pin thermally enhanced
MSOP and low profile (0.75mm) DFN packages.
