If you really need sensorless drive, check Toshiba, they have a nice line of BLDC ICs: https://toshiba.semicon-storage.com/us/product/linear/motordriver/brushless-motor.html --- End quote --- Trying to understand the chart on their site. Looks to me like they only have drivers for 12? Should have mentioned that in my specs. Needs to be 12V or less. Also I don't need a whole lot of current since I am just driving a hard drive motor. |

The "12-volt" parts work at 5.5...22 V. And they're made for sensorless drive. Nice parts (no affiliation). |

But only surface mount :( Did a search on mouser looks like there is not much in the through hole department. |

The TB6633 will do exactly what you want. And SSOP isn't that difficult to solder. |
