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

voltage, or constant die-temperature (CCCVCT

lation for safe operation in handhelds.

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

output, in conjunction with the low-R

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.
