Power mgmt IC for TI's 32-bit MCUs in 5 x 5 mm QFN package

Texas Instruments Incorporated (TI) has 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 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.

Key features and benefits of TPS75005 as per TI include:

Optimized managed power supply to TI's 32-bit C2000 real-time control MCUs, including preset power-up and power-down sequencing.
High integration: Dual 500-mA voltage regulators (linear dropout regulators) with dedicated supply voltage supervisor.
Voltage accuracy and protection: Five-percent accuracy enhances power design reliability.

The TPS75005 supports input voltages from 3.5 V to 6.5 V, 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.

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