Texas Instruments DRV8350S | Demoboard DRV8350S-EVM
DRV8350S three-phase smart gate driver evaluation module
Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 12-95 V |
| Switching frequency | 200 kHz |
| Output 1 | 3.3 V / 15 A |
| IC revision | A |
Description
The DRV8350S-EVM is a 15A, 3-phase brushless DC drive stage based on the DRV8350S gate driver and CSD19532Q5B NexFET™ power blocks. The module has individual DC bus and phase voltage sense as well as an external, individual low-side current shunt amplifier, making this evaluation module ideal for sensorless BLDC algorithms. The module supplies MCU 3.3V and 5V power blocks from a 12 V, 0.35A step down buck regulator. The driver can be configured in split rail and single rail power solutions. The drive stage has IDRIVE configuration, along with a fault pin and protection for short circuit, thermal, shoot-through, and under voltage conditions through configurable SPI. The EVM has an entire USB to MCU environment to program and evaluate the EVM using available trapezoidal drive firmware and GUI.
Features
- 12- to 95-V operation
- 15 A continuous / 20 A peak H-bridge output current
- Complete evaluation module with hall sensor connection along with programmable MSP430F5529
- One individual, external low-side current shunt amplifiers
- Trapezoidal sensored and sensorless BLDC firmware available
- Hardware interface to configure IDRIVE, MODE, VDS monitoring, and GAIN
Typical applications
- Fans, Blowers, and Pumps / Drones, Robotics, and RC Toys / E-Bikes, E-Scooters, and E-Mobility / Factory Automation and Textile Machines
- 3-Phase Brushless-DC (BLDC) Motor Modules / Power and Garden Tools, Lawn Mowers
