LM2907M-14 from HGSEMI, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | TACH+ | input | Input signal positive terminal; connected to non-inverting input of internal Schmitt trigger comparator. |
| 2 | CP1 | output | Charge pump output; capacitor charges at 180µA typical constant current to VCC/2 on each positive half-cycle, discharges at same rate on negative half-cycle. |
| 3 | CP2 | output | Charge pump current output equal to absolute value of CP1 capacitor current; resistor and capacitor in parallel filter current pulses to output voltage. |
| 4 | IN+ | input | Non-inverting input of high-gain operational amplifier. |
| 5 | EMIT | power_in | Emitter of output stage bipolar junction transistor; provides ground return path for open-collector output. |
| 6 | NC | unconnected | No connection. |
| 7 | NC | unconnected | No connection. |
| 8 | COL | tri_state | Collector of open-collector output transistor; sinks up to 50mA and supports voltage to VCE max 28V. |
| 9 | V+ | power_in | Positive power supply voltage; operating range 0 to 28V DC. |
| 10 | IN- | input | Inverting input of high-gain operational amplifier. |
| 11 | TACH- | input | Input signal negative terminal; connected to inverting input of internal Schmitt trigger comparator. |
| 12 | GND | power_in | Ground; negative power supply return. |
| 13 | NC | unconnected | No connection. |
| 14 | NC | unconnected | No connection. |
