ACT72350
160 V 3-phase BLDC Motor Driver with Integrated Power Manager and Configurable AFE
Key Features
- 160 V buck DC/DC controller with external NCH FET
- 5 V / 200 mA system supply
- 3 high-side 160 V 2 A (source) / 2 A (sink) gate drivers
- 3 low-side 20 V 2 A (source) / 2 A (sink) gate drivers
- Advanced cycle-by-cycle protection
- 3 differential PGA (x1 to x48)
- 4 single PGA (x1 to x48)
- Programmable over-current shutdown
- Programmable comparator hysteresis and blanking
- Simultaneous sample and hold for three-phase
Qorvo's ACT72350 is a standalone three-phase BLDC motor driver with an Analog Front End (AFE) that allows customers to drive up to 20 S battery power with a 160 V rating. The AFE powers the system MCU while delivering up to 2 A source/-2 A sink drive capability. The overall BOM is reduced significantly through integrated bootstrap diodes, and all analog blocks needed to measure current and protect the device. This device utilizes Qorvo's patent pending Multi-Mode Power Manager™, Configurable Analog Front End™, and Application Specific Power Drivers™ and also contains a robust braking feature for safety critical applications.
Typical Applications
- Industrial BLDC Motor Control (Pumps, Fans, Robotics)
- Power and Garden tools
- Small Appliances
- E-mobility
