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.

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

for single-cell Li+ or three-cell NiMH/NiCd batteries.

Alternatively, the MAX1501 collaborates with a host

microprocessor to determine the best charging algorithm.

Proprietary thermal-regulation circuitry limits the die

temperature when fast charging or while exposed to high

ambient temperatures, allowing maximum charging

current without damaging the charger. The MAX1501

continually supplies a regulated output voltage under

no-battery conditions, allowing battery changing.

The device achieves high flexibility by providing an

adjustable fast-charge current, top-off current, safety

timer, and thermal-regulation setpoint. Other features

include input power detection (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.
