MAX1940EEE+T

Overview

The MAX1940EEE+T is a triple-switch USB power switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 4V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device is housed in a 16-SSOP (QSOP) surface-mount package. It features a low supply current of 60µA, making it suitable for portable applications requiring efficient power management for multiple USB peripherals.

Feature Summary

• Integrates three independent high-side switches for USB peripheral power control
• Supports single-supply operation with low quiescent current consumption
• Designed for compact surface-mount packaging in portable electronics

Applications

• USB hub power distribution
• Portable computer peripheral power management
• Multi-port USB charging stations

Procurement Notes

Verify the exact datasheet specifications directly from Analog Devices or authorized distributors before procurement. Confirm that the 16-SSOP package dimensions and thermal characteristics match your PCB layout requirements. Ensure the supply voltage range aligns with your system's power rails. Check for any specific ordering suffixes or tape-and-reel quantities if applicable to your manufacturing process.

Selection Notes

Select this component when designing circuits requiring independent control of up to three USB ports from a single 5V rail. Consider its low standby current for battery-operated devices. Evaluate the thermal performance within the 16-SSOP package against your expected load currents. Ensure compatibility with USB specification voltage tolerances and protection requirements.

Part Context

This part belongs to the Maxim Integrated family of USB power switches, designed specifically for managing power delivery to downstream USB devices. It simplifies board design by integrating multiple switches and control logic into a small footprint, reducing component count compared to discrete solutions.
