ROHM Semicon · Brushed DC Motor Drivers · HTSSOP-28-EP
BD62220AEFV-E2 from ROHM Semicon, in a HTSSOP-28-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 wiring impedance from this terminal should be made as low as possible to reach the lowest electrical potential in any operating state. |
| 2 | OUT1B | output | H bridge output terminal for channel 1, which carries motor drive current and has a built-in clamp against electrostatic destruction that must not be exceeded by surge voltage. |
| 3 | RNF1 | passive | Connection terminal of the output-current detection resistor, which should be 0.1 Ω to 0.3 Ω and must not be left open or shorted to GND. |
| 4 | RNF1S | input | Input terminal of the channel 1 current limit comparator, which must be connected to RNF1 when PWM constant current control is used. |
| 5 | OUT1A | output | H bridge output terminal for channel 1, which carries motor drive current and has a built-in clamp against electrostatic destruction that must not be exceeded by surge voltage. |
| 6 | NC | unconnected | No connection; the terminal is electrically unconnected to the internal circuit. |
| 7 | VCC1 | power_in | Power supply terminal that must be shorted externally to VCC2 and bypassed with 100 µF to 470 µF close to the pin, with the supply kept within the 8 V to 28 V recommended range and never exceeding the 36 V absolute maximum. |
| 8 | NC | unconnected | No connection; the terminal is electrically unconnected to the internal circuit. |
| 9 | GND | power_in | Ground terminal; the wiring impedance from this terminal should be made as low as possible to reach the lowest electrical potential in any operating state. |
| 10 | CR | passive | Connection terminal for the switching-frequency timing network, which requires an external C of 330 pF to 680 pF and R of 10 kΩ to 150 kΩ to GND and must not be left open when PWM constant current control is used. |
| 11 | VREF1 | input | Current limit value setting terminal for channel 1, where VREF must stay within 0 V to 2.0 V and must not be left open. |
| 12 | VREF2 | input | Current limit value setting terminal for channel 2, where VREF must stay within 0 V to 2.0 V and must not be left open. |
| 13 | PS | input | Power save terminal where L puts the circuit into standby with motor outputs open and H enables active operation, with a delay of up to 40 µs when returning from standby. |
| 14 | TEST1 | input | Test terminal that must be connected to GND, since it may malfunction if left unconnected. |
| 15 | FAILA | output | Open-drain fault output that goes low on over-current protection or thermal shutdown, and requires a 5 kΩ to 100 kΩ pull-up to a supply below 7 V (such as 5 V or 3.3 V). |
| 16 | IN1A | input | H bridge control input for channel 1 that sets forward, reverse, brake, or open output logic together with IN1B and PS. |
| 17 | IN1B | input | H bridge control input for channel 1 that sets forward, reverse, brake, or open output logic together with IN1A and PS. |
| 18 | TEST2 | input | Test terminal that must be connected to GND, since it may malfunction if left unconnected. |
| 19 | IN2A | input | H bridge control input for channel 2 that sets forward, reverse, brake, or open output logic together with IN2B and PS. |
| 20 | IN2B | input | H bridge control input for channel 2 that sets forward, reverse, brake, or open output logic together with IN2A and PS. |
| 21 | NC | unconnected | No connection; the terminal is electrically unconnected to the internal circuit. |
| 22 | VCC2 | power_in | Power supply terminal that must be shorted externally to VCC1 and bypassed with 100 µF to 470 µF close to the pin, with the supply kept within the 8 V to 28 V recommended range and never exceeding the 36 V absolute maximum. |
| 23 | NC | unconnected | No connection; the terminal is electrically unconnected to the internal circuit. |
| 24 | OUT2A | output | H bridge output terminal for channel 2, which carries motor drive current and has a built-in clamp against electrostatic destruction that must not be exceeded by surge voltage. |
| 25 | RNF2S | input | Input terminal of the channel 2 current limit comparator, which must be connected to RNF2 when PWM constant current control is used. |
| 26 | RNF2 | passive | Connection terminal of the output-current detection resistor, which should be 0.1 Ω to 0.3 Ω and must not be left open or shorted to GND. |
| 27 | OUT2B | output | H bridge output terminal for channel 2, which carries motor drive current and has a built-in clamp against electrostatic destruction that must not be exceeded by surge voltage. |
| 28 | NC | unconnected | No connection; the terminal is electrically unconnected to the internal circuit. |
| 29 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
