MAX1501
Highly Integrated, Linear Battery Charger with
Thermal Regulation for Portable Applications

General Description
The MAX1501 intelligent, constant-current, constant-
voltage (CCCV), temperature-regulated battery charger
charges a single lithium-ion (Li+) cell or three-cell
NiMH/NiCd batteries. The device integrates the current-
sense resistor, PMOS pass element, and thermal-
regulation circuitry, while eliminating the reverse-
blocking Schottky diode to create the simplest charging
solution for hand-held equipment.
For single-cell Li+ batteries, the MAX1501 functions as a
stand-alone charger to control the charging sequence
from the prequalification state through fast charge, top-
off, and charge termination. With
3-cell NiMH/NiCd
batteries, the MAX1501 requires collaboration with a
microcontroller to determine the best charging algorithm.
Proprietary thermal-regulation circuitry limits the die tem-
perature when fast charging or while exposed to high
ambient temperatures, allowing maximum charging cur-
rent without damaging the charger. The MAX1501 con-
tinually supplies a regulated output voltage under
no-battery conditions, allowing battery changing without
interrupting system power.
The device achieves high flexibility by providing an
adjustable fast-charge current, top-off current, safety
timer (disabled in the MAX1501Z), and thermal-regula-
tion setpoint. Other features include input power detec-
tion (ACOK) and input under-/overvoltage protection.
The MAX1501 provides active-low control inputs.
The MAX1501 accepts a 4.5V to 13V supply, but
disables charging when the input voltage exceeds
6.5V, preventing excessive power dissipation. The
MAX1501 operates over the extended temperature
range (-40°C to +85°C) and is available in a compact
16-pin thermally enhanced 5mm x 5mm thin QFN
package with 0.8mm profile.
