The LTC

1733 is a standalone constant-current/

constant-voltage linear charger for lithium-ion batteries

with an on-chip power MOSFET. Internal thermal feedback

regulates the charge current to limit die temperature

during high power operation or high ambient temperature

conditions. This feature allows the user to program a high

charge current without risk of damaging the LTC1733 or

the handheld product.

No external current sense resistor is needed and no

blocking diode is required due to the internal MOSFET

architecture. The charge current and charge time can be

set externally with a single resistor and capacitor, respec-

tively. When the input supply (wall adapter) is removed,

the LTC1733 automatically enters a low current sleep

mode, dropping the battery drain current to less than 5µA.

The LTC1733 also includes NTC temperature sensing,

C/10 detection circuitry, AC present logic, 4.1V/4.2V pin

selectability and low battery charge conditioning (trickle

charging).

The LTC1733 is available in a 10-pin thermally enhanced

MSOP package.
