8.2.3 Application Curves

The power supply sequencing for VBIAS, VOFFSET and VRESET are shown in Figure 8-2 and Figure 8-3. On power-up, the turn on of VBIAS enables the external VRESET voltage regulator. In power-down, when VBIAS powers off, it disables the VRESET regulator, which slowly decays to ground.

The power sequencing for VCC2 voltage regulator is shown in Figure 8-4 and Figure 8-5. The power up of VOFFSET enables the turn on of the VCC2 voltage regulator. As seen in the zoom out of Figure 8-4, the 1.8-V supply is already on and stable. Similarly, the power down of VOFFSET disables the VCC2 voltage regulator. The 1.8-V supply powers down after both VOFFSET and VCC2 are powered down, as seen in the zoom out of Figure 8-5.
