SC811 / SC813

Adapter/USB Tri-Mode

Single-cell Li-ion Charger

POWER MANAGEMENT

Features

Description

The SC811 and SC813 are highly versatile single input

triple mode (adapter/USB high current, USB low current)

linear single-cell Li-ion battery chargers, each in an 8 lead

2x2 MLPD ultra-thin package. The input will survive sus-

tained input voltage up to 30V to protect against hot plug

overshoot and faulty charging adapters. The SC811 has

9.6V rising, 8.2V falling OVP thresholds for general purpose

charging with low cost adaptors. The SC813 has 6V rising,

5.6V falling OVP thresholds for customers utilizing charg-

ing adapters with speciﬁcations that are similar to a USB

Vbus supply. The SC811 and SC813 differ only in OVP

threshold.

Single input charger with three charging modes

Constant voltage — 4.2V, 1% regulation

Fast-charge current regulation — 15% at 70mA,

9% at 700mA

Charging by current regulation, voltage regulation,

and thermal limiting

Input voltage protection — 30V

Current-limited adapter support capability — reduces

power dissipation in charger IC

USB high and low power modes limit charge current

to prevent USB Vbus overload

Instantaneous CC-to-CV transition for faster charging

Programmable battery-dependent currents (adapter

mode fast- and pre-charge, termination)

Programmable source-limited currents (USB-high

mode fast-charge, and USB-low mode fast- and

pre-charge)

Charging begins automatically when an input source is

applied to the charging input. Thermal limiting protects

against excessive power dissipation. The charger can be

programmed to turn oﬀ when charging is complete or to

continue operating as an LDO regulator while ﬂoat-charg-

ing the battery.

Independent programming of termination current

with dual-mode operation

Three charging modes are provided: adapter mode, USB

low power mode, and USB high power mode. Battery-

capacity-dependent and charging source-dependent

current programming are independently programmed.

Adapter and USB high power modes can charge up to 1A,

with the charging adapter operating either in voltage

regulation or in current limit to obtain the lowest possible

power dissipation. A single current programming pin is

used to program pre-charge, termination, and adapter-

mode fast-charge currents in fixed proportions. In the

USB modes, a second programming pin is used to program

low power pre-charge current and low and high power

fast-charge currents. This conﬁguration allows indepen-

dent programming of termination current. The two USB

modes dynamically limit the charging load if necessary to

prevent overloading the USB Vbus supply.

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 or USB load transients

High operating voltage range of SC811 permits use

of unregulated adapters

Complies with CCSA YD/T 1591-2006

Space saving 2x2x0.6 (mm) MLPD package

WEEE and RoHS compliant
