Description

The MAX8606ETD+T is one member of the MAX8606 series. MAX8606ETD+T has the following features including (1)small 3mm x 3mm thermally enhanced TDFN package (0.8mm max height);(2)selectable 100mA, 500mA, and up to 1A input current limits;(3)automatic current sharing between battery charging and system;(4)charge status and input-supply detection flags.

The MAX8606ETD+T complete 1-cell Li+ battery charge-management IC operates from either a USB port or AC adapter. It integrates a battery disconnect switch, current-sense circuit, PMOS pass element, and thermal-regulation circuitry, while eliminating the external reverse-blocking Schottky diode, to create a simple and small charging solution. The charging sequence of MAX8606ETD+T initiates from power-OK indication, through prequalification, fast-charge, top-off charge, and finally charging-complete indication for single-cell Li+ batteries.Charging is controlled using constant current, constant voltage, or constant die-temperature (CCCVCTJ) regulation for safe operation in handhelds.Two logic inputs (EN1 and EN2) of MAX8606ETD+T select suspend mode,100mA, 500mA, or 1A input current limits to suit USB requirements. Proprietary thermal-regulation circuitry limits the die temperature to +100°C to prevent excessive heat on the system PC board. Additional safety features include an NTC thermistor input (THM) and internal timers to protect the battery. A 3.5V to 4.2V SYS output, in conjunction with the low-RDSON battery switch, powers the system even when the battery is deeply discharged or not installed. The IC MAX8606ETD+T also offers a +3.3V/500A output (VL), a charging status flag (CHG),and an input-supply detection flag (POK). The MAX8606 operates from a +4.25V to +5.5V supply and includes undervoltage lockout below +3.4V and over-voltage protection up to +14V.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.The MAX8606ETD+T charger uses current, voltage, and thermal control loops to charge and protect a single Li+ battery cell. It can start the system even when the battery is in deep saturation. The MAX8606ETD+T provides a SYS output that supplies the external system with a minimum 3.5V at 1A.
