SC811 Description
The SC811 is 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 sustained 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 charging adapters with specifi cations that are similar to a USB Vbus supply. The SC811 and SC813 differ only in OVP threshold.
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 fl oat-charging the battery.
Three charging modes are provided: adapter mode, USB low power mode, and USB high power mode. Batterycapacity-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 adaptermode 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 confi guration allows independent programming of termination current. The two USB modes dynamically limit the charging load if necessary to prevent overloading the USB Vbus supply.
