TIDA-00827 is an integrated sensor-based BLDC motor controller reference design for low-power, battery-powered brushless DC motor applications. The 8 to 35V operating voltage range supports 3S to 6S lithium polymer battery power supplies. Specific applications include camera heads, low-power fans and robots. The motor controller consists of the MSP430G2353 16-bit, ultra-low power microcontroller and the DRV8313 highly integrated 2.5A triple half-bridge driver. The MSP430G2353 utilizes Hall sensor-based communication feedback to provide the correct drive voltage to the motor through the DRV8313. Onboard potentiometers and buttons provide a simple interface to control the motor.
The PMP10733 uses the LM5160 in a Fly-Buck-Boost topology with the primary side set to a negative voltage. Setting the primary side to a negative voltage reduces the turns ratio of the transformer and therefore allows for better line and load regulation. The primary and secondary voltages are set to negative 15V and positive 15V respectively. The maximum operating current on the primary and secondary voltage rails is set to 150mA. The switching frequency is set to 200kHz.
This reference design functions from a base of silicon carbide (SiC) MOSFETs that are driven by a C2000 microcontroller (MCU) with SiC-isolated gate drivers. The design implements three-phase interleaving and operates in continuous conduction mode (CCM) to achieve a 98.46% efficiency at a 240-V input voltage and 6.6-kW full power. The C2000 controller enables phase shedding and adaptive dead-time control to improve the power factor at light load. The gate driver board (see TIDA-01605) is capable of delivering a 4-A source and 6-A sink peak current. The gate driver board implements a reinforced isolation and can withstand more than 100-V/ns common-mode transient immunity (CMTI). The gate driver board also contains the two-level turnoff circuit, which protects the MOSFET from voltage overshoot during the short-circuit scenario.

TIDA-00447 is a 24V, dual brushless DC (BLDC) motor drive reference design that can be used to drive circulating water pumps and drain pumps in dishwashers. The circulating water pump and drainage pump drive stages are designed for continuous operation of 100W and 30W respectively. The drain pump driver is based on a single-chip, low external component count three-phase motor driver with integrated power MOSFETs and provides a proprietary sensorless control scheme enabling continuous sine wave drive. In addition, it features an integrated buck/linear regulator that efficiently reduces the supply voltage to 5V or 3.3V to power internal and external circuitry. The circulating water pump is implemented using a discrete solution with MCU, external MOSFET driver with protection mechanism and current sensing function, and external power MOSFET. This architecture allows the flexibility to adjust drive power levels as needed. The MCU is programmed through the InstaSPIN-BLDC software, which enables sensorless trapezoidal control of the BLDC motor using an anti-EMF integration approach, and can also be used to configure and control the speed of the drainage pump stage. A separate UART interface allows the drive unit to communicate with the main user interface controller. This reference design has been fully tested with current and motor stop protection mechanisms operating at full load.
