ROHM Semicon · Stepper Motor Driver · HTSSOP-20-EP
BD63610AEFV-E2 from ROHM Semicon, in a HTSSOP-20-EP. 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 | GND | power_in | Ground terminal; the backside metal is shorted to the chip backside and should be connected to GND. |
| 2 | OUT1B | output | H-bridge output terminal for channel 1 (B side). |
| 3 | RNF1 | passive | Connection terminal of the resistor for output current detection on channel 1; the RNF maximum voltage is 0.7 V. |
| 4 | OUT1A | output | H-bridge output terminal for channel 1 (A side). |
| 5 | VCC1 | power_in | Power supply terminal; supply voltage range is 19 to 28 V recommended (absolute maximum -0.2 to +36.0 V). |
| 6 | CR | passive | Connection terminal for the CR network that sets the PWM oscillation. |
| 7 | GND | power_in | Ground terminal. |
| 8 | VREF | power_in | Output current value setting terminal. |
| 9 | PS | input | Power save terminal. |
| 10 | CLK | input | Clock input terminal for advancing the motor step (description is truncated in the source text). |
| 11 | TEST0 | input | Terminal for testing; must be connected to GND. |
| 12 | CW_CCW | input | Motor rotating direction setting terminal. |
| 13 | MODE | input | Motor excitation mode setting terminal. |
| 14 | TEST1 | input | Motor excitation mode setting terminal. |
| 15 | ENABLE | input | Terminal for enabling the output. |
| 16 | GND | power_in | Grounding terminal. |
| 17 | VCC2 | power_in | Power supply terminal for channel 2 (the printed table lists this row as 'Non connection', which conflicts with the pin name and the application circuit). |
| 18 | OUT2A | output | H-bridge output terminal for channel 2 (A side) (the printed table lists this row as 'Power supply terminal', which conflicts with the pin name). |
| 19 | RNF2 | passive | Connection terminal of the resistor for output current detection on channel 2 (the printed table lists this row as 'Non connection', which conflicts with the pin name and the block diagram). |
| 20 | OUT2B | output | H-bridge output terminal for channel 2 (B side). |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
