MAX16943EGEE/V+

Overview

The MAX16943EGEE/V+ is a high-side USB power switch IC designed for overcurrent protection and power distribution. It operates within a supply voltage range of 4.75 V to 5.25 V, with a nominal operating voltage of 5 V. The device supports a maximum continuous current limit of 1 A and features a typical on-resistance of 57 mΩ. It includes programmable timing controls, offering a maximum turn-on time of 10 ms and a maximum idle time of 1 ms. The component is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Provides integrated high-side switching with precise overcurrent limiting capabilities for USB port protection.
• Features programmable soft-start and idle timeout timers to manage inrush currents and detect disconnections.
• Includes thermal shutdown protection to safeguard the device and connected loads during fault conditions.

Applications

• USB hub power distribution circuits
• Portable electronic device charging ports
• Industrial USB interface protection modules

Procurement Notes

Verify the specific suffix 'V+' against official Analog Devices documentation to confirm automotive qualification status and RoHS compliance details. Confirm package marking codes match the QSOP-16 specification. Check current availability status as distribution channels may indicate limited stock or end-of-life constraints for this specific variant.

Selection Notes

Select this component when designing systems requiring robust USB overcurrent protection with adjustable timing parameters. Ensure the load current does not exceed the 1 A limit and that the operating environment stays within the specified -40°C to +105°C range. Verify compatibility with the 5 V USB standard voltage requirements.

Part Context

This part belongs to the MAX16943E series of USB protector ICs manufactured by Analog Devices / Maxim Integrated. It is specifically engineered for high-side power switching applications where reliable fault detection and controlled power delivery are critical for maintaining system integrity and preventing damage to upstream hosts.

Replacement Considerations

Consult official cross-reference guides for direct pin-compatible alternatives. Verify that any substitute maintains identical current limiting thresholds, timing characteristics, and package dimensions to ensure seamless integration without redesigning the PCB layout.
