Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One terminal electrode of the 2 mΩ alloy current-sense resistor (1206, 3.20 x 1.60 mm, 0.50±0.20 mm electrode width, 1 W rated at up to +70 °C ambient, derated linearly to 0 at +170 °C); the resistor is non-polarized so terminals are interchangeable. |
| 2 | 2 | passive | Other terminal electrode of the 2 mΩ alloy current-sense resistor (1206, 3.20 x 1.60 mm, 0.50±0.20 mm electrode width, 1 W rated at up to +70 °C ambient, derated linearly to 0 at +170 °C); the resistor is non-polarized so terminals are interchangeable. |
