TC78H660FTG from TOSHIBA, in a VQFN-16-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN1A / Phase A | input | A channel IN1 input in IN mode (MODE=Low) or A channel Phase input in Phase mode (MODE=High); logic high 1.5 V to 5.5 V, low 0 to 0.7 V. |
| 2 | AGND | power_in | Ground pin. |
| 3 | VM | power_in | Motor power supply input pin, operating range 2.5 V to 16.0 V. |
| 4 | PGND_A | power_in | A channel power ground pin. |
| 5 | OUT_A+ | output | A channel motor output (+) pin, rated up to 2.0 A. |
| 6 | OUT_A- | output | A channel motor output (-) pin, rated up to 2.0 A. |
| 7 | OUT_B- | output | B channel motor output (-) pin, rated up to 2.0 A. |
| 8 | OUT_B+ | output | B channel motor output (+) pin, rated up to 2.0 A. |
| 9 | PGND_B | power_in | B channel power ground pin. |
| 10 | VREF | power_in | Current threshold reference pin, 0 to 1.8 V, with peak output current Iout(max) = 1.1 × Vref. |
| 11 | OSCM | passive | Internal oscillator frequency setting pin; an external resistor ROSC sets the chopping frequency (47 kΩ gives about 79 kHz). |
| 12 | STBY | input | Standby pin; Low selects standby mode and High selects normal mode. |
| 13 | MODE / ERR | bidirectional | Control mode select input (Low = IN mode, High = Phase mode) and error flag output that goes Low on TSD/ISD; needs a pull-up to High for Phase mode or error output, and the output voltage is rated up to 5.5 V. |
| 14 | IN2A / Phase B | input | A channel IN2 input in IN mode (MODE=Low) or B channel Phase input in Phase mode (MODE=High). |
| 15 | IN1B / Enable A | input | B channel IN1 input in IN mode (MODE=Low) or A channel Enable input in Phase mode (MODE=High). |
| 16 | IN2B / Enable B | input | B channel IN2 input in IN mode (MODE=Low) or B channel Enable input in Phase mode (MODE=High). |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
