Nevertheless, as general guides for the power up sequence:

- First, you have to switch on the electronics, in a random way if you want, but making sure that no current from the DEPFET is flowing into the DCDB, meaning that you have to keep Source off.

- Then, you can configure the chips.

- Finally, you can ramp up the clear and gate and finally, source.

As a precaution, you should make first GateON=GateOFF before switching the Source on. Only move the GateOn to the final voltage after setting Source to the 7V nominal.

Here you have the list of "standard" voltages:

DHP1.2=1.2V
DHP1.8=1.8V
DCDAmpLow=1.55V
DCDRefIn=1.2V
VDDA=1.9V
VDDD=1.8V
ClearGate=-2V
Bulk=-10V
Source=7V
VDD/Vref=3.3V
Backplane=-18V
Drift=-3V
ClearHigh=22V
ClearLow=19V
GateHigh=3.0
GateLow=-6.45V
