MAX14637CVB+T

Overview

The MAX14637CVB+T is a USB charge detection IC designed for identifying connected devices and charging ports. It operates within a supply voltage range of 3.5V to 5.5V, with a maximum operating supply current of 150µA. The component supports an input voltage range up to 28V and functions reliably across an operating temperature range of 0°C to 70°C. Packaged in a compact 10-UTQFN (1.6x2.1) surface-mount format, it integrates specialized power management features for efficient peripheral connectivity.

Feature Summary

• Identifies USB host and charging port types for optimized power delivery
• Supports high-side hot-swap controller evaluation and operation
• Compact 10-UTQFN package design for space-constrained applications

Applications

• USB peripheral device integration
• Mobile phone and tablet charging systems
• Portable electronic device power management

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm that the 10-UTQFN footprint matches the target PCB layout dimensions. Ensure the selected variant meets the required thermal dissipation standards for the intended enclosure environment. Cross-reference the manufacturer's latest datasheet for any updates to pinout definitions or recommended soldering profiles prior to production implementation.

Selection Notes

Select this component for applications requiring precise USB charge negotiation without complex external logic. The low supply current makes it suitable for battery-powered portable devices where energy efficiency is critical. Consider the 28V input tolerance if interfacing with higher voltage bus lines. The small form factor allows for integration into slim consumer electronics designs where board real estate is limited.
