MAX14670EWL+T

Overview

The MAX14670EWL+T is a bidirectional current-blocking, high-input overvoltage protector featuring an adjustable overvoltage lockout (OVLO). It operates within a supply voltage range of 2.1V to 5.5V and supports a maximum input voltage up to 36V. The device incorporates a low on-resistance N-channel MOSFET with a typical value of 80mΩ. Key electrical parameters include a quiescent current of 1µA, an input leakage current of 10nA, and a response time of 1µs. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Bidirectional current blocking capability prevents reverse current flow while protecting against overvoltage conditions.
• Adjustable overvoltage lockout threshold allows for precise protection level configuration via external resistors.
• Ultra-low power consumption design ensures minimal impact on battery life in portable applications.
• Integrated N-channel MOSFET provides low on-resistance for efficient power transmission.

Applications

• Portable consumer electronics requiring battery protection
• USB host and device port protection circuits
• Smartphone and tablet power management systems
• General purpose overvoltage protection for low-voltage DC lines

Procurement Notes

Verify the specific suffix 'EWL+T' corresponds to the WLP-9 package and tape-and-reel delivery format. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the supplier provides valid traceability documentation for Analog Devices/Maxim Integrated products. Check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement orders.

Selection Notes

Select this component when bidirectional current blocking is required alongside adjustable overvoltage protection. The low quiescent current makes it suitable for battery-powered devices where standby power conservation is critical. Consider the 80mΩ on-resistance for efficiency requirements. Evaluate the 36V input rating against the system's maximum transient voltage levels to ensure adequate safety margins.
