General Description
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
J
) regu-
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
DSON
battery
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.
