NXP 33HB2001 10A H桥SPI编程无刷马达驱动方案

NXP公司的33HB2001是SMARTMOS单片10A H桥驱动集成电路,具有SPI可配置性和诊断功能,峰值电流大于10A,正常连续电流为3.0A,工作电压5.0 V - 28 V,具有超温保护,欠压保护和短路保护.本文介绍了33HB2001主要特性,功能框图,典型应用电路以及评估板FRDM-HB2001-EVM主要特性,框图和电路图,材料清单和PCB图.
The 33HB2001 is a SMARTMOS monolithic H-Bridge Power IC, enhanced with SPI configurability and diagnostic capabilities. It is designed primarily for DC motor or servo motor control applications within the specified current and voltage limits.
The 33HB2001 is able to control inductive loads with peak currents greater than 10 A. The nominal continuous average load current is 3.0 A. A current mirror output provides an analog feedback signal proportional to the load current.
This part is designed to specifically address the ISO 26262 safety requirements.
33HB2001主要特性:

•Advanced diagnostic reporting via a serial peripheral interface (SPI): charge pump undervoltage, overvoltage, and undervoltage on VPWR, short to ground and short to VPWR for each output, open load, temperature warning, and overtemperature shutdown
•Thermal management: Excellent thermal resistance of <1.0℃/W between junction and case (exposed pad)
•Eight selectable slew rates via the SPI: 0.25 V/s to more than 16 V/s for EMI and thermal performance optimization
•Four selectable current limits via the SPI: 5.4/7.0/8.8/10.7 A covering a wide range of applications
•Can be operated without SPI with default slew rate of 2.0 V/s and a 7.0 A current limit threshold
•Highly accurate real-time current feedback through a current mirror output signal with less than 5.0% error
•Drives inductive loads in a full H-Bridge or Half-bridge configuration
•Overvoltage protection places the load in high-side recirculation (braking) mode with notification in H-Bridge mode
•Wide operating range: 5.0 V to 28 V operation
•Low R...
