MAX22444/ MAX22445/ MAX22446 Reinforced, Fast, Low-Power, Four-Channel Digital Isolators

The MAX22444–MAX22446 are reinforced, fast, low-power 4-channel digital galvanic isolators. These devices transfer digital signals between circuits with different power domains, using as little as 0.74mW per channel at 1Mbps (1.8V supply).

All of the devices in the family feature reinforced isolation for a withstand voltage rating of 5kVRMS for 60 seconds. The MAX22444–MAX22446 family offers all possible unidirectional channel configurations to accommodate any 4-channel design, including SPI, RS-485, and digital I/O applications.

Key Features:

  • Up to 200Mbps Maximum Data Rate
  • Withstands 5kVRMS for 60s (VISO)
  • Continuously Withstands 1500VRMS (VIOWM)
  • Withstands ±10kV Surge Between GNDA and GNDB with 1.2/50µs waveform
  • High CMTI (50kV/µs, Typical)
  • 0.74mW per Channel at 1Mbps with VDD = 1.8V
  • 1.4mW per Channel at 1Mbps with VDD = 3.3V
  • 3.2mW per Channel at 100Mbps with VDD = 1.8V
  • 2 Maximum Data Rates (200Mbps, 25Mbps)
  • 3 Direction Configurations
  • 2 Fixed Output Default States (High/Low) or Pin-Selectable (M/N Versions)


  • Battery Management
  • Isolated RS-485/RS-422, CAN
  • Isolated SPI Interface
  • Medical Systems

MAX17263 - Single/Multi-Cell Fuel Gauge with ModelGauge m5 EZ and Integrated LED Control

The MAX17263 is an ultra-low power fuel gauge which implements Maxim ModelGauge™ m5 EZ algorithm. The MAX17263 monitors either a single cell battery pack or multiple-series cell battery pack with an external resistor divider.

The IC drives 3 to 12 automatically-counted LEDs to indicate battery state-of-charge on a push-button press, or any other system status using I2C commands.

Key Features:

  • ModelGauge m5 EZ
  • Monitors Single Cell or Multiple-Series Cell Battery Pack
  • Integrated LED Control with Push-Button Input
  • Custom Pattern LED Control Using I2C Commands
  • Accurate Current Sensing
  • Wide Sense Resistor Range: 1mΩ to 1000mΩ
  • PCB Metal Sensing + Temperature Compensation
  • Supports Li+ and Variants Including LiFePO4
  • Thermistor or ±1°C Internal Temperature
  • Dynamic Power Estimates Power Capability During Discharge
  • Time-to-Empty and Time-to-Full Estimation
  • Predicts Remaining Capacity Under Theoretical Load
  • No Calibration Required
  • Alert Indicator for Voltage, SOC, Temperature, Current, and 1% SOC Change


  • Battery Backup
  • Drones
  • Headlamps and Torches
  • Medical Devices
  • Power Tools
  • Toys
