概览

MC33039 是一款高性能闭环速度控制适配器，特别适用于无电刷直流电机控制系统。实施之后可进行精确的速度调节，而无需磁性或光学转速表。该器件包含三个输入缓冲器且每个均带有实现抗扰性的迟滞，还包括三个数字边缘检测器、可编程单稳态和内部分路稳压器。另外还包括一个逆变器输出，用于需要传感器相位转换的系统。尽管此器件主要用于 MC33035 无电刷电机控制器，但它也可成本高效地用于很多其他闭环速度控制应用中。

  • Digital Detection of Each Input Transition for Improved Low Speed Motor Operation
  • TTL Compatible Inputs With Hysteresis
  • Operation Down to 5.5 V for Direct Powering from MC33035 Reference
  • Internal Shunt Regulator Allows Operation from a Non-Regulated Voltage Source
  • Inverter Output for Easy Conversion between 60°/300° and 120° /240° Sensor Phasing Conventions
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
