Key Document
Description
This reference design provides a compact system design capable of supporting motor acceleration and deceleration up to ±200 kRPM/s, which is a key requirement in many respirator applications. The design supports a number of offboard C2000 controllers including the TMS320F28027F, enabling a low-cost, sensor-less field oriented control (FOC). In addition, the design supports a wide input voltage range (6-28 V) capable of supporting both regulated line and battery power. To drive the air blower and valves, this design uses the DRV8323RS smart gate driver and DRV8847 motor driver, respectively.
Features
- Fast acceleration and deceleration up to ±200 kRPM/s
- 10 kRPM to 40 kRPM in 250 ms (C65MS1-L5)
- 40 kRPM to 10 kRPM in 200 ms (C65MS1-L5)
- Wide input voltage range (6-28 V) supporting regulated DC or battery input with power protection to prevent surge, over-current, and reverse polarity
- DRV8323RS motor driver with off-board FOC control for quiet and efficient pressurized air generation
- Integrated driver protection features including UVLO, overcurrent, and overtemperature
