The MAX22245/MAX22246 are a family of 2-channel reinforced, fast, low-power digital galvanic isolators using Maxim’s proprietary process technology. All devices feature reinforced isolation for a withstand voltage rating of 5kVRMS for 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperatures of -40°C to +125°C.

Devices with /V suffix are AEC-Q100 qualified. Refer to the Ordering Information for all automotive grade part numbers.

  • Industrial
  • Isolated SPI
  • Isolated RS-232, RS-485/RS-422, CAN
  • Fieldbus Communications
  • Motor Drive

These devices transfer digital signals between circuits with different power domains, using as little as 0.78mW per-channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs.

Devices are available with a maximum data rate of 25Mbps or 200Mbps, and with outputs that are either default high or default low. The devices feature low propagation delay and low clock jitter, which reduces system latency.

Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators.

The MAX22245 features two channels transferring data in the same direction. The two channels of the MAX22246 transfer data in opposite directions, and this makes the MAX22246 ideal for isolating the Tx and Rx lines of a transceiver.

Applications

  • Automotive
  • Battery Management Systems (BMS)

Product Detail

The MAX22245/MAX22246/MAX22290/MAX22291 evaluation kits (EV kits) provide a proven design to evaluate the MAX22245, MAX22246, MAX22290 and MAX22291, reinforced, two-channel, galvanic digital isolators. Three types of evaluation boards are available to support this family of isolators. The MAX22246CWEVKIT# is fully assembled and tested and comes populated with the MAX22246CAWA+ (Figure 1). The MAX2224XWEVKIT# is a generic board which has unpopulated wide SOIC footprint as U1, allowing the user to install any MAX22245/ MAX22246 variant (Figure 2). The MAX2229XSEVKIT# is a generic board which has unpopulated narrow SOIC footprint as U1, allowing the user to install any MAX22290/ MAX22291 variant (Figure 3). Among the three evaluation boards, devices with either wide-body 8-pin SOIC package or narrow-body 8-pin SOIC package are supported. See Table 1 for EV kit options.

The EV kits should be powered from two independent isolated power supplies with nominal output voltage in range from 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used.

The MAX2224XWEVKIT# comes with U1 unpopulated and supports the following digital isolators: MAX22245BAWA+, MAX22245CAWA+, MAX22245EAWA+, MAX22245FAWA+, MAX22246BAWA+, MAX22246CAWA+, MAX22246EAWA+, MAX22246FAWA+, MAX22245BAWA/V+, MAX22245CAWA/V+, MAX22245EAWA/V+, MAX22245FAWA/V+, MAX22246BAWA/V+, MAX22246CAWA/V+, MAX22246EAWA/V+, MAX22246FAWA/V+.

The MAX2229XSEVKIT# comes with U1 unpopulated and supports the following digital isolators: MAX22290BASA+, MAX22290CASA+, MAX22290EASA+, MAX22290FASA+, MAX22291BASA+, MAX22291CASA+, MAX22291EASA+, MAX22291FASA+, MAX22290BASA/V+, MAX22290CASA/V+, MAX22290EASA/V+, MAX22290FASA/V+, MAX22291BASA/V+, MAX22291CASA/V+, MAX22291EASA/V+, MAX22291FASA/V+.

Note: When ordering the MAX2224XW EV kit, request a sample of the desired MAX22245 or MAX22246 isolator IC that can be soldered to the PCB. When ordering the MAX2229XS EV kit, request a sample of the desired MAX22290 or MAX22291 isolator IC that can be soldered to the PCB.

Applications

  • Fieldbus Communications for Industrial Automation
  • General Isolation Applications
  • Isolated RS232, RS485/RS422,CAN
