O
This output provides a 1V reference for pre-charging the CompactPCI bus signal
pins.
5V card side supply input. This input is monitored for power integrity. If it falls below
the 5V sense threshold, the CARD_V_VLD signal is de-asserted.
3.3V monitor input from the line card. This input is monitored for power integrity. If it
falls below the 3.3V sense threshold, the CARD_V_VLD signal is de-asserted.

ADC_CAPC
32
I
External capacitor input used to filter the VMC input to the 10-bit ADC.
ADC_CAPB
33
I
External capacitor input used to filter the VMB input to the 10-bit ADC.
ADC_CAPA
34
I
External capacitor input used to filter the VMA input to the 10-bit ADC.
VGG_CAP
35
O
This pin supplies power for the high-side drivers. An external 1uF ceramic charge
pump capacitor should be connected to VGG_CAP. VGG_CAP is a charge storage
connection for the internal charge pump of the SMH4046. This capacitor should be
of sufficient size to provide current to the VGATE outputs high side drivers under
varying load conditions. For most applications this can be tied to a 1.0
μ
F ceramic
capacitor.
High-side driver enable used to switch on the 12V supply. Pulldown current of
100
μ
A when on.
5V gate output. Slew rate limited high side driver output for the 5V external Power
FET gate. Alternatively this can be used as a PUP output.
3.3V gate output. Slew rate limited high side driver output for the 3.3V external
Power FET gate. Alternatively, this can be used as a PUP output.
