Figure 4-5 shows the test results with a supply voltage of 30 V and a 60 Ω resistive load that creates 500 mA of
current. The voltage during the Wake-up pulse is observed to be 28.5 V which is also greater than the VTHHmax
requirement of 13 V resulting in a passing test result.
The Wake-up current pulse low test verifies the low-side driver and consists of observing the voltage VIM during
the Wake-up pulse when a resistive load resulting in 500 mA current is connected. If the voltage VIM is below
the threshold VTHLmin during a Wake-up pulse, this indicates the minimum requirement is met and results in a
passing test result.
Figure 4-6 shows the test results with a supply voltage of 20 V and a resistive load between L+ and C/Q that
creates 500 mA of current. The voltage during the Wake-up pulse is observed to be 0.9 V which is less than the
VTHLmin requirement of 8 V resulting in a passing test result.
