MAX8606 - Li+ Linear Battery Charger

Description

The MAX8606 complete 1-cell Li+ battery charge-management IC operates from either a USB port or AC adapter.

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-R DSON battery switch, powers the system even when the battery is www. DataSheet4U. com deeply discharged or not installed. The IC also offers a +3.3V/500µA 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 overvoltage protecti.

19-3795; Rev 0; 8/05 KIT ATION EVALU E L B A IL AVA USB/AC Adapter, Li+ Linear Battery Charger with Integrated 50mΩ Battery Switch in TDFN General Description The MAX8606 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 thermalregulation circuitry, while eliminating the external reverse-blocking Schottky diode, to create a simple and small charging solution. The charging sequence initiates from power-OK indication, through prequalification, fast-charge, top-off charge, and finally charging-complete indication for single-cell Li+ batteries.
