10. Push the push button SW2 again and check on the oscilloscope screen if the
V_GATE voltage and the PULSE signal are as they are presented in Figure 5-3
and Figure 5-4 .
FIGURE 5-3: MCP1012 Wake-Up Command.
The Wake-Up command consists of a single valid PWM Pulse.
FIGURE 5-4: MCP1012 Wake-Up Command ( Figure 5-3 Detail).
If the external PWM signal ceases for a period greater than 260 μ s typical, then the
gate driver will be driven by the internal current regulator (return to Start-Up mode).
11. Read the voltmeter and check if the output voltage of the board is in the range of
4.5V to 5.5V.
12. Disconnect the DC power supplies.
