TI公司的TIDA-00281是采用UCC27201A-Q1高频N沟MOSFET驱动器的汽车48V 1kW马达驱动参考设计,能处理高达30A的电流,包括和C2000 LaunchPad连接的模拟电路,不需要位置传感器就能控制三相无刷直流马达(BLDC),从48V电池系统供电,具有过压,欠压,超温,过流和瞬时故障保护.本文介绍了UCC27201A-Q1主要特性,功能框图,应用电路图以及TIDA-00281汽车48V 1kW BLDC马达驱动参考设计主要特性,系统指标,应用框图,电路图和材料清单以及pcb设计图.
The UCC27201A-Q1 high frequency N-Channel MOSFET driver includes a 120-V bootstrap diode and high-side/low-side driver with independent inputs for maximum control flexibility. This allows for N-Channel MOSFET control in half-bridge, full-bridge, two-switch forward and active clamp forward converters. The low-side and the high-side gate drivers are independently controlled and matched to 1-ns between the turn-on and turn-off of each other. The UCC27201A-Q1 is based on the popular UCC27200 and UCC27201 drivers, but offer some enhancements. In order to improve performance in noisy power supply environments the UCC27201A-Q1 has the ability to withstand a maximum of -18 V on its HS pin.
An on-chip bootstrap diode eliminates the external discrete diodes. Under-voltage lockout is provided for both the high-side and the low-side drivers forcing the outputs low if the drive voltage is below the specified threshold.
The UCC27201A-Q1 has TTL-compatible thresholds and is offered in a 10-Pin VSON and an 8-pin SOIC with a thermal pad.
