| Power Interface Module (ATCA) | ||
| Open-frame, single board construction for higher reliability |
 |
The IQ65033QMA10 iQor Power Interface Module integrates all features required by the AdvancedTCA Base Specification for a frame board power entry into a Quarter-Brick footprint. Minimal external components are required for all the key functions (see applications drawing below). Efficient utilization of hold-up capacitance with adjustable high-voltage management. Available in standard module or full-feature with I2C interface. |

| 9 | 3.3V | 3.3V (relative to LOGIC_GND) |
| 10 | 12C_ADR | I2C address input * (Connect external resistor to LOGIC_GND) ** |
| 11 | 12C_DAT | I2C data (Relative to LOGIC_GND) * |
| 12 | 12C_CLK | I2C clock (Relative to LOGIC_GND) * |
| 13 | LOGIC_GND | Logic ground |
| 14 | ALARM | Isolated A/B feed loss or open fuse alarm (Relative to LOGIC_GND) |
| 15 | -48V_OUT | Negative output to payload power converter |
| 16 | HU_TRIM | Hold-up voltage trim |
| (Connect external resistor to -48V_OUT) | ||
| 17 | VRTN_OUT | Positive output to payload power converter |
| 18 | HU_CAP | Positive connection to hold-up capacitor (Negative connection to _48V_OUT) |
| Notes: * Pin 10, 11 and 12 are only available on the full featured version. See datasheet (ordering page) for more information. ** Single resistor connected externally to LOGIC_GND selects the three least significant bit of I2C Adress "0101xxx". |
