**TOSHIBA** · Power Distribution Switches · DIP-16

TBD62503APG from TOSHIBA, in a DIP-16. 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 | I1 | input | Input pin for channel 1; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 2 | I2 | input | Input pin for channel 2; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 3 | I3 | input | Input pin for channel 3; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 4 | I4 | input | Input pin for channel 4; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 5 | I5 | input | Input pin for channel 5; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 6 | I6 | input | Input pin for channel 6; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 7 | I7 | input | Input pin for channel 7; for the TBD62503A series, VIN must be at least 2.5 V to turn the output on and at most 0.6 V to turn it off, with absolute maximum VIN of −0.5 to 30 V. |
| 8 | GND | power_in | Ground pin; the datasheet stresses careful GND line design because improper grounding or output short-circuits can destroy the IC. |
| 9 | NC | unconnected | Non-connection pin; the datasheet states no electrical function for it. |
| 10 | O7 | output | Sink output for channel 7, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 11 | O6 | output | Sink output for channel 6, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 12 | O5 | output | Sink output for channel 5, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 13 | O4 | output | Sink output for channel 4, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 14 | O3 | output | Sink output for channel 3, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 15 | O2 | output | Sink output for channel 2, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
| 16 | O1 | output | Sink output for channel 1, rated for a maximum output voltage of 50 V and a maximum output current of 300 mA/ch. |
