Overview

TC3827 Lithium-Ion Battery Charger FEATURES s s s s s s s s s Low Power Dissipation Shutdown Current: 1µA (Typical) Space-Saving 8-Pin MSOP Package No Inductor Required 1% Overall System Accuracy Charge Current Monitor Output Charge Status Indicator Output Foldback Current Limiting –20°C to +85°C Ambient Operating Temperature Range GENERAL DESCRIPTION The TC3827 is a battery charger controller for a single cell Li-Ion battery.
Using an external PMOS transistor, safe and fast charging of a single Li-Ion cell is accomplished.
Features include over-current foldback, charge current monitor, and charge status LED indicator output.
An overall system accuracy of 1% ensures that the cell capacity is fully utilized without cycle life degradation.
An external resistor sets charge current.
The TC3827 operates with an input voltage range from 4.
5V to 5.
5V.
It is specified over the ambient operating temperature range of –20°C to +85°C and is available in a space-saving 8-Pin MSOP.
