24V dual-channel brushless DC motor driver reference design for dishwasher water pumps

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.
