Hardware Configuration
PWRHLD and PWREN must be connected together in CMI 106.
Startup
The ACT8846QM106-T has two startup sequences. The first is pushbutton startup. Asserting nPBIN low
starts the startup sequence. nPBIN must stay low until after PWRHLD and PWREN are asserted high by
an external source, usually a uP. If nPBIN goes high before PWRHLD goes high, the IC shuts down all
outputs. The second startup sequence is with the PWREN and PWRHLD pins. After input power is ap-
plied, asserting PWREN high starts the startup sequence. Note that nPBIN should stay high in this appli-
