SC810

Single Input/Single Mode

Single-cell Li-ion Charger

POWER MANAGEMENT

Features

Description

Input voltage protection — 30V

Single input charger

Constant voltage — 4.2V, 1% regulation

Charging by current and voltage regulation (CC/CV)

Thermal limiting of charge current

Programmable fast-charge current

Current-limited adapter support — reduces power dis-

sipation in charger IC

Instantaneous CC-to-CV transition for faster charging

Three termination options — ﬂoat-charge, automatic

re-charge, or forced re-charge to keep the battery

topped-oﬀ after termination without ﬂoat-charging

Soft-start reduces adapter load transients

High operating voltage range permits use of unregu-

lated adapters

The SC810 is a linear single-cell Li-ion battery charger in a

6 lead 2×2mm MLPD Ultra-thin package. The input will

survive sustained input voltage up to 30V to protect

against hot plug overshoot and faulty charging adapters.

Charging begins automatically when a valid input source

is applied. Thermal limiting protects the SC810 from

excessive power dissipation. It can be programmed to

turn oﬀ when charging is complete or to continue operat-

ing as an LDO regulator while ﬂoat-charging the battery.

The input will charge with an adapter operating in voltage

regulation or in current-limit to obtain the lowest possible

power dissipation by pulling the input voltage down to

the battery voltage. The maximum fast-charge current

setting is 1A.

Complies with CCSA YD/T 1591-2006

Space saving 2×2×0.6 (mm) MLPD package

Pb free, Halogen free, and RoHS/WEEE compliant

Charge current is programmed with a single resistor. Pre-

charge and termination current are ﬁxed at 20% and 10%,

respectively, of the programmed fast-charge current.

Charge current steps up to the programmed value (soft

starts) to reduce load transients on the charging adapter.
