Figure 4-2 shows the INA241x-Q1 and INA296x-Q1 pin diagram for the DGS-10 package. For a detailed description of the device pins, see the Pin Configuration and Functions section in the INA241x-Q1 and INA296x-Q1 data sheet.
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| IN- | 1 | In high-side configuration, a short from the bus supply to GND will occur. High current will flow from bus supply to ground. In low side configuration, normal operation. | B for high side or D for low side |
| NC | 2 | This pin has no internal connection. Normal operation. | D |
| GND | 3 | Normal operation. | D |
| REF2 | 4 | If intended connection is anything other than GND, functionality will be affected. | D if REF2=GND by design; B otherwise |
| NC | 5 | Normal operation. | D |
| OUT | 6 | Output shorts to ground. | B |
| Vs | 7 | Power supply shorted to ground. | B |
| REF1 | 8 | If intended connection is anything other than GND, functionality will be affected. | D if REF1 = GND by design; B otherwise |
| NC | 9 | This pin has no internal connection. Normal operation. | D |
| IN+ | 10 | In high-side configuration, a short from the bus supply to GND will occur. High current will flow from bus supply to ground. In low side configuration, input pins are shorted. | B |
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| IN- | 1 | IN- will be at the same potential as IN+. Differential input voltage is effectively 0V. | B |
| NC | 2 | This pin has no internal connection. Normal operation. | D |
| GND | 3 | GND is floating. Output will be incorrect as it is no longer referenced to GND. | B |
| REF2 | 4 | Device loses reference voltage. | B |
| NC | 5 | This pin has internal weak pull down. Even though possible, the likelihood of malfunction is low. | D |
| OUT | 6 | Output can be left open. There is no effect on the IC. | C |
| Vs | 7 | No power supply to device. Device may be biased through inputs. Output will be close to GND. | B |
| REF1 | 8 | Device loses reference voltage. | B |
| NC | 9 | This pin has no internal connection. Normal operation. | D |
| IN+ | 10 | IN+ will be at the same potential as IN-. Differential input voltage is effectively 0V. | B |
| Pin Name | Pin No. | Shorted to | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|---|
| IN- | 1 | NC | Normal operation. | D |
| NC | 2 | GND | Normal operation. | D |
| GND | 3 | REF2 | If intended connection is anything other than GND, functionality will be affected. | D if REF2 = GND by design; B otherwise |
| REF2 | 4 | NC | Functionality will be affected if REF2 equals to anything but GND by design. | C |
| NC | 5 | OUT | Changing output may affect functionality, but the likelihood is very low. | C |
| OUT | 6 | Vs | Output shorts to supply. | B |
| Vs | 7 | REF1 | Functionality will be affected if REF1 equals to anything but Vs by design. | D if REF1 = Vs by design; B otherwise |
| REF1 | 8 | NC | Normal operation. | D |
| NC | 9 | IN+ | Normal operation. | D |
| IN+ | 10 | IN- | Input differential voltage = 0V | B |
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
