MAX1501

Highly Integrated, Linear Battery Charger with

Thermal Regulation for Portable Applications

General Description

Features

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.

o Stand-Alone 1-Cell Li+ Charging, Microprocessor-

Controlled 3-Cell NiMH/NiCd Charging

o No FET, Reverse-Blocking Diode, or Current-

Sense Resistor Required

o 1.4A (max) Programmable Fast-Charge Current

o +95°C, +115°C, and +135°C Proprietary

Programmable Die Temperature Regulation

Control

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.

o 4.5V to 13V Input Voltage Range with Input

Overvoltage (OVLO) Protection Above 6.5V

o Programmable Top-Off Current Threshold: 10%,

20%, or 30% of the Fast-Charge Current

o Charge-Current Monitor for Fuel Gauging

o Programmable Safety Timer (3, 4.5, or 6 hours)

o Input Power Detection Output (ACOK) and Charge

Enable Input (CHGEN)

o Automatic Recharge

o Digital Soft-Start Limits Inrush Current

o Charge Status Outputs for LEDs or µP Interface

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.

MAX1501ETE

MAX1501ZETE

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.
