The MAX14578EETE+T from Maxim Integrated Products is an USB battery charger detector in 16 pin TQFN package. The USB charger-detection circuitry detects USB standard downstream ports, USB charging downstream ports or dedicated charger ports and controls an external Li+ battery charger. The device implement USB battery charging revision1.1-compliant detection logic including data contact detection, D+/D- short detection, charging downstream port identification. The internal USB switch is compliant to Hi/full/low-speed USB signals. The device feature low on-resistance, low on-resistance flatness and very low capacitance. The device also features high-ESD protection up to ±15KV human body model on the CD+ and CD- pins. In addition, the device feature Apple and Sony charger detection that allows identification of resistor-divider networks on D+/D-. It is used in DSC and camcorder, media players, cell phones, e-book readers and mobile internet devices (MIDs).
