For engineers reviewing the TPS65930A2ZCHR datasheet, TPS65930A2ZCHR pinout, TPS65930A2ZCHR application, or TPS65930A2ZCHR equivalent, key selection criteria include its 139-ball BGA package, I²C programmable power states (SLEEP/ACTIVE/OFF), 96 kHz RX-capable audio path, 480 Mbps USB 2.0 PHY, and support for OMAP2430/OMAP3430 host processors.

Technical Context

The TPS65930A2ZCHR implements a multi-subchip architecture with independent Power, Audio, USB, Auxiliary, and Interface digital/analog domains interconnected via OCP and I²C. Its power subchip uses configurable SMPS and LDOs with programmable output voltages and SLEEP/ACTIVE/OFF modes controlled via I²C registers.

The audio subchip features a dedicated PLL supporting 19.2 MHz, 26 MHz, and 38.4 MHz reference clocks, TDM/I²S interface with master/slave capability, and full-duplex 16-bit stereo conversion at sampling rates up to 96 kHz (RX) and 48 kHz (TX). USB functionality includes a 480 MHz internal PLL, 5 V-tolerant data lines, and ULPI-12 compliance.

FAQ

What is the primary function of the TPS65930A2ZCHR in portable device designs?

The TPS65930A2ZCHR serves as a highly integrated power management and audio codec IC. It delivers regulated power via three stepdown converters and four LDOs, provides 16-bit stereo audio conversion, hosts a USB 2.0 OTG transceiver with ULPI interface, manages keypad and LED functions, and includes RTC and SmartReflex™ dynamic voltage scaling-all in a single 139-ball microBGA package. This consolidation reduces system complexity for OMAP2430/3430-based smartphones and media players.

Does the TPS65930A2ZCHR support USB On-The-Go functionality, and what interface does it use?

Yes, the TPS65930A2ZCHR supports USB 2.0 OTG-compliant high-speed operation up to 480 Mbps. It implements a fully integrated USB physical layer (PHY) with a standardized ULPI-12 interface, enabling direct connection to host controllers such as OMAP processors without requiring external transceivers. The device also includes a 5 V-tolerant data line and on-chip 480 MHz PLL for clock generation.

What audio sampling rates does the TPS65930A2ZCHR support, and how is clocking managed?

The TPS65930A2ZCHR supports audio sampling rates of 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48, and 96 kHz (RX path only). Its dedicated audio PLL accepts 19.2 MHz, 26 MHz, or 38.4 MHz reference clocks and generates precise bit clocks for TDM/I²S interfaces. The device operates as either master or slave, allowing flexible synchronization with host processors or external audio codecs.

How many general-purpose I/Os and keypad lines does the TPS65930A2ZCHR provide?

The TPS65930A2ZCHR includes 15 GPIOs and a dedicated keypad controller supporting up to a 6 × 6 matrix. The keypad module features hardware-accelerated scanning, programmable debounce timing, long-press detection, and interrupt generation-reducing host CPU overhead. GPIOs can be configured as inputs, outputs, or peripheral functions including LED control and vibrator drive.

What thermal and safety protections are built into the TPS65930A2ZCHR?

The TPS65930A2ZCHR incorporates thermal shutdown and hot-die detection circuitry that triggers automatic system protection when junction temperature exceeds safe thresholds. It also includes undervoltage lockout (UVLO) on backup power rails and overcurrent protection (OCP) across SMPS and LDO outputs. These features ensure reliable operation in thermally constrained portable enclosures without requiring external supervision circuitry.
