USB Battery Charger Detectors

Smallest Complete Port Detection Devices to Support USB and Apple Chargers


Please check latest availability status for a specific part variant.

Description

The MAX14578E/MAX14578AE are USB charger detectors compliant with USB Battery Charging Revision 1.1. The USB charger-detection circuitry detects USB standard downstream ports (SDPs), USB charging downstream ports (CDPs), or dedicated charger ports (DCPs), and controls an external lithium-ion (Li+) battery charger.

The devices implement USB Battery Charging Revision 1.1-compliant detection logic including data contact detection, D+/D- short detection, and charging downstream port identification. The MAX14578AE features an enable (active-low EN) input and an LDO output.

In addition, the internal USB switch is compliant to Hi-Speed USB, full-speed USB, and low-speed USB signals. The devices feature low on-resistance, low on-resistance flatness, and very low capacitance. The devices also feature high-ESD protection up to ±15kV Human Body Model on the CD+ and CD- pins.

In addition, the MAX14578E/MAX14578AE feature Apple and Sony charger detection that allows identification of resistor-divider networks on D+/D-.

The MAX14578E/MAX14578AE are available in 12-bump, 0.4mm pitch, 1.3mm x 1.68mm WLP and 16-pin TQFN packages and operate over the -40°C to +85°C extended temperature range.
