For the different OTP options for the t1 to t4 timings see

the respective values in “Configuration Options”.

For power supplies starting at t1, additional delay time

interval is added to the device wake-up time.

The following timing diagram in Figure 4-5 shows the

typical sequence for Case 2:

Start-Up from PWRHLD

Timing Diagram.

For all sequences described above, LPM can be

assumed to be low. The MPU will assert LPM after

some time, based on software decision, to enter the

Low-Power mode.

Where:

t1 = Delay from PWRHLD asserted to first

output VOUT1 starting (default 0.5 ms +

device wake-up time, about 100 µs)

t2 = Time from VOUT1 established to VOUT2

starting (default 8 ms)

t3 = Time from VOUT2 established to VOUT3

starting (default 4 ms)

t4 = Time from VOUT3 established to nRSTO

deassertion (default 16 ms)
