SBAA466 March 2022 ADS7138-Q1
This section provides a failure mode analysis (FMA) for the pins of the ADS7138-Q1. The failure modes covered in this document include the typical pin-by-pin failure scenarios:
Table 4-2 through Table 4-5 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.
| Class | Failure Effects |
|---|---|
| A | Potential device damage that affects functionality. |
| B | No device damage, but loss of functionality. |
| C | No device damage, but performance degradation. |
| D | No device damage, no impact to functionality or performance. |
Figure 4-1 shows the ADS7138-Q1 pin diagram. For a detailed description of the device pins, see the Pin Configuration and Functions section in the ADS7138-Q1 data sheet.
Following are the assumptions of use and the device configuration assumed for the pin FMA in this section:
RC filters are on every analog input, AINx. Series resistors are sized to limit the input currents into the analog inputs to <10 mA in all circumstances (for example, if the device is unpowered and an input signal is applied).

| SCL | 13 | No I2C communication with the device is possible. Increase in supply current when SCL tries to drive low. Device damage plausible if SCL drives low for an extended period of time. | A |
| SDA | 14 |
No I2C communication with device is possible. Increase in supply current when SDA tries to drive low. Device damage plausible if SDA drives low for extended an period of time. |

| AIN0/GPIO0 | 15 | AIN0/GPIO0 is configured as an analog input. The conversion result for this channel will be close to 0xFFF. | B |
| AIN0/GPIO0 is configured as a digital input: GPIO0 is stuck high. The readback value of GPI_VALUE[0] will be 1b. | B | ||
| AIN0/GPIO0 is configured as a digital output: GPIO0 is stuck high. Increase in supply current when GPIO0 tries to drive low. Device damage may be plausible. | A | ||
| AIN1/GPIO1 | 16 | AIN1/GPIO1 is configured as an analog input. The conversion result for this channel will be close to 0xFFF. | B |
| AIN1/GPIO1 is configured as a digital input: GPIO1 is stuck high. The readback value of GPI_VALUE[1] will be 1b. | B | ||
| AIN1/GPIO1 is configured as a digital output: GPIO1 is stuck high. Increase in supply current when GPIO1 tries to drive low. Device damage may be plausible. | A | ||
| Thermal Pad | — |
Device unpowered. Device not functional. Observe that the absolute maximum ratings for all pins of the device are met, otherwise device damage may be plausible. |
