Figure 1. MIC2563A V_PP Timing Diagram
V_PP Enable is shown generically: refer to “MIC2563A-0 and MIC2563A-1 Control Logic Tables.” At time “A,” V_PP = 3.3V is
selected. At “B,” V_PP is set to 12V. At “C,” V_PP = 3.3V (from 12V). At “D,” V_PP is disabled. At “E,” V_PP is programmed to 5V.
At “F,” V_PP is set to 12V. At “G,” V_PP is programmed to 5V. At “H,” V_PP is disabled. At “J,” V_PP is set to 12V. And at “K,” V_PP
is again disabled. R_L = 100Ω for all measurements. Load capacitance is negligible.

Figure 2. MIC2563A V_CC Timing Diagram
V_CC Enable is shown generically: refer to “MIC2563A-0 and MIC2563A-1 Control Logic Tables” for specific control logic input.
At time “A,” V_CC is programmed to 3.3V. At “B,” V_CC is disabled. At “C,” V_CC is programmed to 5V. And at “D,” V_CC is disabled.
R_L = 10Ω.
