MAX14578AEETE+

Battery Chargers Overview

The MAX14578AEETE+T is a USB battery charger detector compliant with USB Battery Charging Revision 1.1, manufactured by Analog Devices Inc./Maxim Integrated. It detects Standard Downstream Ports (SDPs), Charging Downstream Ports (CDPs), and Dedicated Charger Ports (DCPs). The device controls an external lithium-ion battery charger and supports Apple and Sony charger detection via D+/D- resistor-divider networks. It features low on-resistance, low capacitance, and high ESD protection up to Q15kV Human Body Model on CD+ and CD- pins. The part operates over a -40°C to +85°C temperature range and is housed in a 16-pin TQFN package.

Battery Chargers Feature Summary

• Implements USB Battery Charging Revision 1.1-compliant detection logic including data contact detection and D+/D- short detection.
• Features internal USB switch compliant with Hi-Speed, Full-Speed, and Low-Speed USB signals.
• Includes enable input and LDO output for system power management integration.

Battery Chargers Applications

• Portable electronic devices requiring USB charging port identification
• Smartphones and tablets utilizing USB standard downstream ports
• Devices supporting dedicated charger port protocols

Battery Chargers Procurement Notes

Verify the specific suffix 'EETE+' against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production lot.

Battery Chargers Selection Notes

Select this component when USB Battery Charging Revision 1.1 compliance is required for portable electronics. It is suitable for designs needing integrated detection of SDP, CDP, and DCP types alongside Apple and Sony proprietary charger identification. Ensure the design accommodates the 16-pin TQFN footprint and external lithium-ion charger control interface.

Battery Chargers Part Context

This component belongs to the MAX14578 family of USB charger detectors from Maxim Integrated, now part of Analog Devices. The family includes variants like the MAX14578E and MAX14578AE, differing primarily in feature sets such as I2C-controlled dead-battery charging support. These ICs are designed to simplify USB connectivity and charging safety in mobile consumer electronics.

Battery Chargers Replacement Considerations

The MAX14578E is a functional variant within the same series. Verify if I2C-controlled dead-battery charging support is required; if not, the MAX14578E may serve as a substitute. Check pinout compatibility and ensure the replacement meets the specific application's voltage and current requirements.
