on the module. Therefore, the pull-up resistors need to be disabled (or its power rail be turned off)

while the SD_1_PWR_EN turns off the card rail. Otherwise, the module can back feed to the card.

The signal states of the external devices like the RS232 signals of the host PC or the display's HDMI

signals are hard to control by the Verdin module and the carrier board. Therefore, it might be

required to take other countermeasures for preventing the backfeeding of these interfaces.

3.5.4.2

Prototype Testing

For identifying backfeeding on a system with a Verdin module, it is recommended to measure the

IO rails of the different power domains in different scenarios. Different scenarios mean testing

different power states of the systems with different types of peripheral devices plugged in and

turned on. If you can measure any significant residual voltage on an IO rail, further investigations

are required for identifying the source of the backfeeding.

The first option is to unplug external peripherals and observe the residual voltage. If the voltage

drops, the peripheral signals are likely a source of backfeeding. If you measure residual voltage in

one power domain, all the input signals crossing this domain should be checked. Measure the

voltage levels on these inputs. A pin that is the source for backfeeding has a higher voltage than

the residual voltage on its IO rail. Typically, due to the protection diode in the backfeeding path,

the voltage at the input pin is around 200mV to 300mV higher than the residual voltage (see

Figure 70)

Figure 70: Measuring backfeeding current

If a signal features a series resistor, the voltage drop can be used to measure the backfeeding

current. Some signals might not have a series resistor for measuring the current. By adding a load

resistor to the backfeeding signal (for example, a 100

Ω

resistor), the voltage with and without extra

load can be measured. This allows to estimate the internal resistance of the driver by using the

following formula:

With the help of the estimated internal driver resistance, the backfeeding current on the pin can be

estimated by using the following formula (V
