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.

Applications

  • Cell Phones
  • DSC and Camcorder
  • e-Book Readers
  • Media Players
  • MID (Mobile Internet Device)

Product Details

The MAX14578 evaluation kit (EV kit) provides a proven design to evaluate the MAX14578 USB battery charger detector in a 12-bump wafer-level package (WLP). The IC features charger detection compliant to USB Battery Charging Revision 1.1, dedicated charger detection, Apple charger detection, China YD/T1591-compliant charger detection, and USB pass-through communication. The EV kit has various power options to separate the charging current from the system current. The EV kit is self-powered through USB, but needs external power to demonstrate charging. The EV kit features the MAX8903A 1-cell lithium-ion (Li+) DC-DC USB charger for interfacing with the MAX14578 in an application setting.

The EV kit uses Windows XP®-, Windows Vista®-, and Windows® 7-compatible software to provide a simple graphical user interface (GUI) to simplify evaluation. The EV kit GUI enables testing of the IC's features. The EV kit PCBs come with a MAX14578EEWC+ installed.

Applications

  • Cell Phones
  • DSC and Camcorder
  • e-Book Readers
  • Media Players
  • MID (Mobile Internet Device)
