Battery Chargers datasheet and documents for MAX14578EWC+

MAX14578EWC+

Battery Chargers Overview

The MAX14578EWC+ is a USB battery charger detector compliant with USB Battery Charging Revision 1.1, designed for lithium-ion battery management. It detects standard downstream ports (SDPs), charging downstream ports (CDPs), and dedicated charger ports (DCPs). The device controls an external Li+ battery charger and supports Apple and Sony charger detection via resistor-divider networks on D+/D-. It features data contact detection, D+/D- short detection, and optional dead-battery charging support controlled by I2C communication. Operating over the -40°C to +85°C range, it is housed in a 16-pin TQFN package.

Battery Chargers Feature Summary

Compliant with USB Battery Charging Revision 1.1 standards for reliable port identification
Integrates high-ESD protection up to Q15kV Human Body Model on CD+ and CD- pins
Supports Apple and Sony proprietary charger detection through D+/D- analysis
Features low on-resistance and very low capacitance internal USB switch

Battery Chargers Applications

USB-powered portable electronic devices requiring battery management
Smartphones and tablets utilizing USB charging infrastructure
Consumer electronics implementing USB Battery Charging 1.1 compliance
Devices requiring detection of dedicated or charging downstream ports

Battery Chargers Procurement Notes

Verify the specific suffix 'WC+' indicates the WLP package variant when cross-referencing with distributor listings that may list the base part number. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the application circuit matches the 16-pin TQFN or 12-bump WLP requirements as specified in the official datasheet for the exact ordering code.

Battery Chargers Selection Notes

Select this component when strict adherence to USB Battery Charging Revision 1.1 is required for port detection logic. It is suitable for designs needing integrated ESD protection on data lines and support for proprietary charger identification protocols like Apple and Sony. Consider the operating voltage range of 2.8V to 28V for power supply compatibility.

Battery Chargers Part Context

This device belongs to the MAX14578E family of USB charger detectors from Analog Devices/Maxim Integrated. It complements other PMIC solutions by providing specialized interface detection rather than general power regulation. The family includes variants like the MAX14578AE which adds an enable input and LDO output, offering flexibility for different system integration needs.
