Analog Devices / Maxim Integrated MAX25460EVKIT Evaluation Kit
Analog Devices MAX25460EVKIT Evaluation Kit facilitates the evaluation of the MAX25460 automotive USB Type-A controller with 1GHz BW USB 2.0 D+/D- protection switches. The MAX25460 supplies a high-current, high-efficiency host charger with port detection circuitry adhering to the USB 2.0 and the USBIF BC1.2 battery charging specifications.
The Analog Devices MAX25460EVKIT evaluation kit is populated with the MAX25460ATGA/V+ for 2.2MHz operation. The high-speed data switches of the MAX25460 typically do not require far-end eye tuning, so the kit is populated with 0Ω resistors in place of the LC turning circuits.
The evaluation kit allows the 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
