MAX77818

Dual Input, Power Path,

3A Switch Mode Charger with Fuel Gauge

General Description

Beneﬁts and Features

● Smart Power Path, Dual Input Switching Charger

• Up to 13.4V Operating/16V Withstand/4A (CHGIN)

• Up to 6V Operating/1.26A (WCIN)

TheMAX77818integratesahigh-performance3Aswitching

charger and proprietary ModelGauge™ m5 fuel gauge

in a space saving WLP package, ideal for USB powered

portable devices. The smart power path charger sup-

ports two inputs with reverse blocking and USB On-the-

Go (OTG), integrates all power switches, operates at

high-switching frequency with high efficiency, enabling

low heat designs with small external components. The

ModelGauge m5 algorithm combines the excellent short-

term accuracy and linearity of a coulomb counter with

the long-term stability of a voltage-based fuel gauge,

along with temperature compensation to provide industry-

leading fuel-gauge accuracy. The device also integrates

two high voltage input LDOs and is highly programmable

• Reverse Leakage Blocking

• Reverse Boost with up to 5.1V/1.5A (OTG)

• Integrated Low-Loss FETs for 3A Charging/4.5A

Discharging

• 95.6% Peak Efﬁciency at 5V/4.35V

• Full Feature Charger with Protection

• Thermal Regulation and JEITA Compliance

● ModelGauge m5 Fuel Gauge

• Time-to-Empty and Time-to-Full Prediction

• Accurate Battery Capacity (SOC) and

Time-to-Empty Readings

with I C interface.

- Temperature, Age, and Discharge Rate

Compensated

- No Calibration

- Integrated FET Current Sensing

- Maintains Accuracy without Empty, Full,

or Idle States
