MAX14750AEWA+T

Overview

The MAX14750AEWA+T is a specialized power management integrated circuit designed for space-constrained wearable electronics. It integrates three non-isolated outputs, including two programmable micro-IQ switching converters (a buck-boost and a synchronous buck) and a low-dropout linear regulator. The device supports an input voltage range of 1.8V to 5.5V with adjustable output voltages from 900mV to 5V. Operating in a compact 25-WLP package, it features burst mode efficiency at light loads and functions as a power switch to interrupt static loads.

Feature Summary

• Integrates dual high-efficiency switching converters and a programmable LDO within a single compact footprint
• Provides configurable power sequencing, delayed reset signals, and custom button timing for system control
• Features ultra-low quiescent current operation with burst mode technology to maximize battery life during light load conditions

Applications

• Wearable electronic devices requiring extended battery life
• Space-constrained battery-powered applications
• Non-rechargeable battery systems or removable battery solutions

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration against official Analog Devices documentation. Confirm that the 'A' grade designation aligns with required temperature and performance specifications. Ensure compatibility with the MAX14750EVKIT for development validation prior to final procurement authorization.

Selection Notes

Select this component when system architecture demands integrated power switching, regulation, and sequencing in minimal area. It is appropriate for designs where true shutdown capability and programmable power-on sequences are critical. Consider its suitability for both rechargeable and non-rechargeable battery topologies based on application requirements.

Part Context

This part belongs to the MAX14720/50 family of small power management solutions by Analog Devices. These components are engineered to extend battery runtimes in portable devices. The MAX14750 variant specifically assists chargers or PMICs in rechargeable applications, offering pin-direct control for flexible power management strategies compared to the standalone MAX14720.

Replacement Considerations

MAX14720AEWA+T serves as a related family member for non-rechargeable or standalone configurations.
