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.
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.
