USB/AC Adapter, Li+ Linear Battery Charger  
with Integrated 50mΩ Battery Switch in TDFN  
MAX806  
General Description  
Features  
Small 3mm x 3mm Thermally Enhanced TDFN  
The MAX8606 complete 1-cell Li+ battery charge-man-  
agement IC operates from either a USB port or AC  
adapter. It integrates a battery disconnect switch, cur-  
rent-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  
initiates from power-OK indication, through prequalifi-  
cation, fast-charge, top-off charge, and finally charg-  
ing-complete indication for single-cell Li+ batteries.  
Charging is controlled using constant current, constant

Charging and System  
Die Temperature Regulation (+100°C)  
Prequal, Fast-Charge, and Top-Off Timers  
Low Dropout Voltage, 250mV at 0.5A  
NTC Thermistor Input  
Two logic inputs (EN1 and EN2) 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 exces-  
sive 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

switch, powers the system even when the battery is  
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 over-  
voltage protection up to +14V.
