Product Details

This evaluation kit (EV kit) demonstrates the MAX25460 automotive USB Type-A controller with 1GHz BW USB 2.0 D+/D- protection switches. The MAX25460 features a high-current, high-efficiency, host-charger with portdetection circuitry adhering to the USB 2.0 and the USBIF BC1.2 battery charging specifications. The step-down DC-DC converter operates from up to 28V continuous and protects against load dump transients up to 40V. The converter switches at 2.2MHz and can deliver 1.5A continuously and 2.4A for up to 1.1ms. The MAX25460 integrates high-side current sensing and circuitry to automatically adjust the USB voltage to compensate for voltage drops in long automotive cables.

The EV kit is populated with a MAX25460ATGA/V+ product variant for 2.2MHz operation. The high-speed data switches of the MAX25460 generally do not require far-end eye tuning, so the EV kit is populated with 0Ω resistors in place of the LC turning circuits.

The EV kit allows evaluation of the following MAX25460 capabilities:

  • Adjustable buck converter precision current limit for better system performance.
  • Adjustable current limit debounce timer for overcurrent testing and system flexibility.
  • Adjustable gain settings for cable compensation for low-cost captive cables up to 474mΩ.
  • Electromagnetic interference (EMI) mitigation using spread spectrum switching.
  • Detailed interrupt and fault status providing multilayer protection and recovery to improve system decisions during faults.
