Introduction

MAX1641EEE+T is a higher power battery chargerFamily of Maxim Integrated’s Power Management Integrated Circuit (PMIC) solutions. It consists of a power switchingcontroller and power FET that controls the current in the charging/discharging cycle of Li-Ion/Li-Polymer/NiMH/NiCd batteries. The charger supports direct charging from a wall adapter, USB charging port, or a stand-alone charger. The device is suitable for use in mobilephone, tablet, andappliancechargerapplications.

Features

Some of the featuresof the MAX1641EEE+T PMIC batteryCharger include maximuminput current limited to 4A, charger current up to 2A with user-selectable 50mA increments, battery detect SemiconductorOscillator with fixed frequency, and Auto-restart Single-channel Power_On/Off Controller with user-selectable voltage. Additionally, other features for MAX1641EEE+T include automaticcharge termination, floatvoltage regulation, charge status output and chargeFET reverse voltage protection.

Application Field

MAX1641EEE+T is a useful solution forapplications such as mobile phones, tablets, and small householdappliances, such as notebooks,cameras andcamcorders, TV sets and game consoles.It can offer up to 2A ofchargingcurrent enabling devices tochargebatteries in a shortertime frame. The fast rate ofcharge ensures thatit is compliant with the energy savingstandards accepted in many countries. Additionally, the charger is suitable for applicationswhere long charging times and wide variations of selfdischarge effects are expected.

Working Principle

The MAX1641EEE+T PMIC charger is designed to run a charging cycle when powered with an AC orDC adapter, or a stand-alone charger. The charger measures thevoltage of the battery and compares it to the voltage set by a user-defined threshold. When the voltage islesser than this threshold, and thecharger is powered up, the charging cycle is initiated. The charging cycle consists of an initial induction current, constant voltage and a termination charge. The initial induction current is responsible for bringing the battery up to the desiredvoltage before continuing the charging cycle. The charger then charges the battery at a constant voltage, untilthe current begins to increase and the voltage eventually begins to decline. Once the decline reaches a specified level, the charger terminates the charge, andsets the charging status to the full chargevoltage.The Constant Voltage phase may run for some time, as it depends on the capacity ofthe battery beingcharged. Additionally, thechargermonitors the battery temperature anddisables charging if the temperature is out of range. Thecharger also disables the electronic circuit when an overcurrent or overriding occurs.

Conclusion

The Max1641EEE+T PMIC Charger is a useful solution forcharging batteries ina variety ofapplications. It canoffer up to 2A ofcharging current, charge batteries in short time frames, andprovide safety andreliability with automaticcharge termination and reverse voltage protection. Additionally, it is suited to wide variations of charge/discharge effects and offers acharge-termination voltage option –allowing it to be used in applications that require long charging times. The MAX1641EEE+Tback-up battery is a low-cost andefficient solution forcharging batteries in amultitude ofdevices.
