EMC5755
Standalone 1.2A Linear Li-Ion Battery Charger
with Thermal Regulation in TDFN-6
General Description
The EMC5755 is a complete linear charger for single cell
lithium-ion batteries. With small TDFN-6 package and
few external components, EMC5755 is well suited for
portable applications. In addition, the EMC5755 is
specifically designed to work within USB power
specifications.
No external sense resistor and blocking diode are
required. Charging current can be programmed
externally with a single resistor. The built-in thermal
regulation facilitates charging with maximum power
without risk of overheating.
The EMC5755 always preconditions the battery with
1/10 of the programmed charge current at the
beginning of a charge cycle, until 40μs after it verifies
that the battery can be fast-charged. The EMC5755
automatically terminates the charge cycle when the
charge current drops to 1/10th the programmed value
after the final float voltage is reached.
The EMC5755 consumes zero reverse current from the
battery at standby, shutdown and sleep modes. This
feature reduces the charge and discharge cycles on
the battery, further prolonging the battery life. The
EMC5755 can also be used as a LDO when battery is
removed. Other features include shutdown mode,
charge current monitor, under voltage lockout,
automatic recharge and status indicator.
