Texas Instruments TWL5030 Power Management (Catalog name TPS65950)

Motorola uses CPCAP caption for that chip.

Description

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.

  3. Embedded 10-bit ADC with 3 to 8 external inputs
  4. Real-time clock (RTC) module and retention modules
  5. uC with vendor specific sized fast turn ROM to provide for programmable regulator defaults and start-up timing
  6. 4k bytes of RAM (< 1uA leakage) for uC application code
  7. HS inter-integrated circuit I2CTM serial control
  8. Thermal shutdown protection and hot-die detection
  9. Keypad up to 8 x 8 matrix
  10. 0.4 mm pitch, 7 x 7 mm package
