MAX1564ETE+

Specialized Overview

The MAX1564ETE+ is a triple, current-limited USB power switch housed in a 16-pin, 4mm x 4mm Thin QFN package. It supports an input voltage range of 2.75V to 5.5V and delivers up to 1.2A per channel with a typical on-resistance of 80mΩ at 3V. The device features user-programmable current limiting via the SETI pin, reverse-current blocking, and thermal shutdown at +160°C. Independent open-drain fault outputs (FLT_) indicate overcurrent or thermal events after a 20ms blanking period. Auto-restart functionality tests shorted outputs with 25mA upon fault removal.

Specialized Feature Summary

• Triple-channel architecture with independent control and fault monitoring for each output
• Programmable current limiting using an external resistor connected to the SETI pin
• Reverse-current protection circuitry that blocks backflow from output to input
• Auto-restart mechanism that detects short-circuit removal and restores power

Specialized Applications

• USB Ports
• USB Hubs
• Notebook Computers
• Desktop Computers
• Docking Stations

Specialized Procurement Notes

Verify the component designation includes the plus suffix to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the specific TQFN-EP package variant required for the design. Confirm the manufacturer source is Analog Devices or Maxim Integrated to guarantee authenticity and traceability.

Specialized Selection Notes

Select this component when a compact solution for multiple USB ports is required within a 4mm x 4mm footprint. Consider the programmable current limit range defined by the SETI resistor values. Evaluate the thermal dissipation requirements based on the maximum on-resistance and expected load currents to ensure operation within the junction temperature limits.

Specialized Part Context

The MAX1564ETE+ belongs to the MAX1564 series of USB power switches manufactured by Analog Devices / Maxim Integrated. It is designed specifically for portable computing and peripheral applications requiring robust power distribution and protection against electrical faults in space-constrained environments.
