Introduction
The TPS65950 device is a highly integrated power-management and audio coder/decoder (codec)
integrated circuit (IC) that supports the power and peripheral requirements of the OMAP™ application
processors. The device contains power management, an audio codec, a universal serial bus (USB)
high-speed (HS) transceiver, an ac/USB charger, light-emitting diode (LED) drivers, an analog-to-digital
converter (ADC), a real-time clock (RTC), and embedded power control.
The power portion of the device contains three buck converters, two controllable by a dedicated
SmartReflex™ class-3 interface, multiple low-dropout (LDO) regulators, an embedded power controller
(EPC) to manage the power-sequencing requirements of OMAP, and an RTC and backup module. The
RTC can be powered by a backup battery when the main supply is not present, and the device contains a
coin-cell charger to recharge the backup battery as needed.
The USB module provides a HS 2.0 on-the-go (OTG) transceiver suitable for direct connection to the
OMAP universal transceiver macrocell interface (UTMI) + low pin interface (ULPI) with an integrated
charge pump (CP) and full support for the carkit Consumer Electronics Association (CEA)-936A
specification.
The Li-ion battery charger supports charging from ac chargers, USB host devices, USB chargers, or
carkits. The type of charger is detected automatically by the device, which provides hardware-controlled
linear charging with ac chargers, USB chargers, and carkits, in addition to software-controlled charging for
all charger types.
The audio codec in the device includes five digital-to-analog converters (DACs) and two ADCs to provide
multiple voice channels and stereo downlink channels that can support all standard audio sample rates
through several inter-IC sound (I2S™)/time division multiplexing (TDM) format interfaces. The audio output
stages on the device include stereo headset amplifiers, two integrated class-D amplifiers providing stereo
differential outputs, predrivers for line outputs, and an earpiece amplifier. The input audio stages include
three differential microphone inputs, stereo line inputs, and interface for digital micrphones. Automatic and
programmable gain control is available with all necessary digital filtering, side-tone functions, and
pop-noise reduction.
The device also provides a auxiliary modules, including LED drivers, and ADC, keypad interface, and
general-purpose inputs/outputs (GPIOs). The LED driver can power two LED circuits to illuminate a panel
or provide user indicators. The drivers also provide pulse width modulation (PWM) circuits to control the
illumination levels of the LEDs. The ADC monitors signals entering the device, such as supply and
charging voltages, and has multiple additional external ADC inputs for system use. The keypad interface
implements a built-in scanning algorithm to decode hardware-based key presses and to reduce software
use, with multiple additional GPIOs that can be used as interrupts when they are configured as inputs.
This TPS65950 Data Manual describes the electrical and mechanical specifications for the TPS65950. It
covers the following topics:
TPS65950 terminals: Assignment, multiplexing, electrical characteristics, and functional description
(see Section 2, Terminal Description)
Electrical characteristic requirements: Maximum and recommended operating conditions, digital
input/output (I/O) characteristics (see Section 3, Electrical Characteristics)
Power module, including the power provider, power references, power control, power consumption,
and power management with the on and off sequences (see Section 4, Power Module)
RTC and EPC (see Section 5, Real-Time Clock and Embedded Power Controller)
Audio/voice module with the electrical characteristics and the application schematics for the downlink
and uplink paths (see Section 6, Audio/Voice Module)
