The TIDA-00771 is a 20A RMS driver for three-phase brushless DC (BLDC) motors in power tools powered by 3-cell Li-ion batteries (voltage range 5V to 12.6V). The design is a compact 45 x 50 mm actuator that enables sensor-based trapezoidal control. The design uses a discrete compact MOSFET-based three-phase inverter that delivers 20A RMS continuous (70A peak for 1 second) winding current without the need for any external cooling devices or heat sinks. The gate driver's slew rate control and charge pump ensure maximum inverter efficiency (>97% at 10.8V DC) from 5V to 12.6V with optimal EMI performance. Cycle-by-cycle overcurrent protection prevents large stall currents in the power stage, and the board can operate in ambient temperatures up to 55°C. The small form factor allows placement of the plate close to the battery pack, the high efficiency allows the battery to last longer, and the 70A peak current capacity delivers high instantaneous peak torque in power tools.
This reference design provides design ideas for a cost-effective, low-power liquid-level measurement data acquisition system (DAS) using a compensated silicon pressure sensor and a high-precision delta-sigma ADC. This document discusses how to select the compensated silicon pressure sensor, suggest system algorithms, and provide noise analyses. It also describes calibration ideas to improve system performance while also reducing complexity and cost.
