2 Sequencing

Figure 2-1 shows the generic power up and power down timing diagram. Startup delay is the delay from the rising edge of ENABLE signal. Shutdown delay is the delay from the falling edge of ENABLE signal. Note that the ENABLE pin assignment/control method and exact power up and power down sequencing depends on the timing values defined in the OTP and specified in Table 2-1.
