The TIDA-00601 design uses isolated shunt sensors to implement a Class 0.5% three-phase energy metering system. Isolation is achieved by using an isolated Delta-Sigma modulator with a capacitively isolated output circuit.

This TI reference design combines a Texas Instruments (TI) low-voltage H-bridge motor driver with an integrated LDO voltage regulator and an ultra-low-power microcontroller (MCU) to demonstrate a comprehensive implementation of a battery-powered electric toothbrush. .
Brushed motors are a relatively popular motor design option due to their low price and simple control scheme. A brushed motor has a wound rotor and a permanent magnet stator. The motor is commutated via a conductive ring: this ring is connected to the rotor, which uses a brush to scrape against the commutator ring, thus commutation is achieved. Therefore, the direction of current flowing through the motor can change depending on the brush orientation and different commutation rings. Simple direction changes and speed control changes can be quickly and efficiently implemented on brushed DC motors using an H-bridge. An electronic driver is required to control the motor current in a brushed DC motor. The electronic drive circuit contains a power stage with a two-phase inverter (to meet the required power intensity), a microcontroller for implementing motor speed commands and fault handling, a current sensing function for motor start/stop protection, for control Gate drivers for two-phase inverters and power supplies for microcontrollers and other low-voltage devices.
The TIDA-00643 reference design is a 4.4 to 30 V brushless DC motor controller for high power propeller, fan and pump applications.

To meet energy efficiency requirements, ceiling fans and ventilation fans will move from simple AC induction motors to brushless DC motors (BLDC). BLDC motors require AC-DC conversion with high efficiency and high power factor when operating on AC power. It also requires the use of highly efficient controlled inverters for low-noise operation. Reference design TIDA-00652 uses a single-stage power supply to convert an AC power input to a low-voltage DC output, helping meet the challenges of higher efficiency and power factor in a simpler way. It also incorporates a fully integrated and properly protected single-chip sensorless sinusoidal brushless motor controller for low-noise operation.

The bidirectional converter uses automatic phase shedding and offset technology for light loads and uses adaptive dead-band optimization to achieve greater than 96% compound efficiency gain. Because efficiency is greatly improved, heat losses are reduced, eliminating the need for air or liquid cooling in automotive applications. In addition, using the UCD3138 high control frequency controller and hardware-based state machine allows for miniaturization and frees up the system CPU for other functions such as battery management.
