TI Introduces Power Management IC for 32-Bit Real-Time Control MCUs

November 30, 2011 by Jeff Shepard

Texas Instruments Inc. (TI) introduced a complete power management solution for TI’s C2000 real-time control, 32-bit microcontrollers (MCUs) and other DSP and FPGA processors. The TPS75005 highly integrated power circuit comes in a thermally enhanced 5 mm x 5 mm QFN package, combining two low-noise 500-mA LDOs and three supply voltage supervisors to provide ±5 percent power-rail accuracy for TI’s F2833x, F2823x, F281x, F2801x and F280x microcontroller series.

The TPS75005 supports input voltages from 3.5 to 6.5V, and provides two power outputs controlled by an integrated sequencer circuit. A single EN logic input signal ensures the power-up and power-down requirements of the C2000 MCUs. The sequencer includes a soft-start for both LDOs to avoid inrush current. A third rail monitor also provides general power management functions, such as monitoring the input voltage.

Key features and benefits of TPS75005:

&ndash: optimized managed power supply to TI’s 32-bit C2000 real-time control MCUs, including preset power-up and power-down sequencing.

&ndash: high integration: Dual 500-mA voltage regulators (linear dropout regulators) with dedicated supply voltage supervisor.

&ndash: voltage accuracy and protection: Five-percent accuracy enhances power design reliability.

The TPS75005 is available in volume now from TI and its distributors in a 20-pin, 5 x 5mm QFN. Suggested resale pricing is $1.90 in 1,000-unit quantities.
