1 / 48 page  General Description The MAX14616/MAX14616A are a complete solution for interfacing to a micro-USB connector and include an advanced charger detection block, a linear battery charger, and a switch block capable of multiplexing USB, UART, audio, and composite video signals. The devices include an LED driver for battery charge status and bat- tery present detection. The MAX14616/MAX14616A support multiplexing USB 2.0 Hi-Speed, UART, and stereo audio signals with a single micro-USB connector. The USB channel features low 3Ω (typ) on-resistance and 7pF (typ) on capacitance to minimize USB signal degradation. The audio inputs feature negative rail signal operation down to -2V and 0.1Ω on-resistance flatness for low THD. The MAX14616/MAX14616A charger detection block supports USB Battery Charger Detection Revision 1.1 requirements and also detects many common non-USB- defined power adapters. The SFOUT LDO provides a voltage-limited USB VBUS output for powering devices such as USB transceivers that cannot withstand high voltage. The MAX14616/MAX14616A include a compos- ite video cable unplug detector capable of detecting the removal of a video termination resistor. The MAX14616/MAX14616A battery charger adds a bat- tery present detector to automatically disable the battery charger in case the battery is removed. They also include an open-drain LED driver to indicate the battery charger operation status. The MAX14616/MAX14616A are available in a 25-bump (2mm x 2mm, 0.4mm pitch) WLP package and operates over the -40°C to +85°C extended temperature range.
