Pinout
6Low source legibility.The original manufacturer datasheet for this part was difficult to read, so this pinout may be incomplete or imperfect. Always confirm against the specific manufacturer’s datasheet before wiring.
| Pin | Name | Functions | Notes |
|---|---|---|---|
| TACH+ | Positive tachometer input | GPIO | Input signal leading to the noninverting terminal of the internal Schmitt-Trigger comparator. |
| TACH–/GND | Negative tachometer input / Ground | GPIO | Input signal leading to the inverting terminal of the internal Schmitt-Trigger comparator; internally connected to ground on 8-pin devices. |
| V+ | Supply voltage | POWER | Supply voltage input. |
| COL | Collector of bipolar junction transistor | GPIO | Output from the collector of a bipolar junction transistor. |
| IN+ | Noninverting input to high gain op amp | GPIO | Input for the noninverting terminal of the high gain op amp. |
| IN– | Inverting input to high gain op amp | GPIO | Input for the inverting terminal of the high gain op amp. |
