handsets– High-Speed USB on USB and UART Inputs Portable Media Players/ MP3 Players– Negative Voltage Rail on Audio Inputs Internal LDO forID Detection and MIC Bias DESCRIPTION– Compatible with USB Charging The LP8727 is designed to provide automaticSpecification Rev. 1.1 multiplexing switches between Micro/Mini USB– DSS Input for Default Switch Connection connector and USB, UART and Audio paths in
cellular phone applications.It also containsa single-– Low-Power MIC Standby Mode input Li-Ion battery charger and an overvoltage-• Linear Charge with Single Input protected LDO. Programmingis handled via anI2C-– 28 OVP on VBUS Input compatible Serial Interface allowing control of
charger, multiplexing switches, and reading status– High-Current Mode for Production Test
informationof the device.– Thermal Regulation
The multiplexing switches on USB and UART support• Over-Voltage Protected LDO for USB high-speed USB, and Audio inputs can be driventoTransceivers and PMU Wakeup negative voltage rail. The LP8727is compatible with• UVLO (Undervoltage Lock Out) USB charging specifications rev 1.1 from USBIF.• Interrupt Requestto Reduce SW Polling The Li-Ion charger requires few external components– USB/ID Detection and integrates the power FET. Chargingis thermally SEND/ END Button Detection regulatedto obtain the most efficient charging rate for given ambient temperature.It has Overvoltage– Mic Removal Protection (OVP) circuitat the charger input protects– OVLO/ UVLO on VBUS the PMU from input voltages upto +28V, eliminating– Charger Status the needfor any external protection circuitry. Thermal Shutdown Protection An overvoltage-protected LDO which can supply upI2 C-compatible Serial Interface to 50 mAis designed for powering upa low-voltage
USB transceiver or waking upa PMU (Power• 25-Bump 0.4 mm Pitch Thin DSBGA Package Management Unit) when an external power source
(either USB VBUSor wall adapter)is connectedto
the USB connector.
The LP8727 PMUis availablein 25-bump 0.4 mm
pitch thin DSBGA package (2.015 mmx 2.015 mm).
