Logic supply voltage.
Supplies analog circuitry portion of the gate driver. Should be at the
same potential as DV
Gate drive supply voltage. Supplies digital circuitry portion of the
gate driver and the main output stage for Out-PA2, Out-NA2, Out-
NA3, Out-PB2, Out-NB2, and Out-NB3. Should be at the same
potential as AV
Gate drive supply voltage. Supplies digital circuitry portion of the
gate driver and the main output stage for Out-PA1, Out-NA1, Out-
PB1, and Out-NB1. Can be at a different potential than DV
Gate drive supply voltage for Out-PA3 and Out-PB3. Supplies
digital circuitry portion and the main output stage. Should be at the
same potential as AV
Negative driver supply for Out-PA3, Out-PB3 and bias circuits.
They are also connected to the IC substrate. They are required to
connect to the most negative potential of voltage supplies.
Digital Ground.
Analog Ground.
Logic input control for channel A. When SEL = L, the pin is POSA.
When SEL = H, the pin is POS1A.
Logic input control for channel A. When SEL = L, the pin is NEGA.
When SEL = H, the pin is NEG1A.
Logic input control for channel A. When SE L= L, the pin is
HVEN1A. When SEL = H, the pin is POS2A.
Logic input control for channel A. When SEL = L, the pin is
HVEN2A. When SEL = H, the pin is NEG2A.
Used with SEL = H. Logic input control for Out-PA3 and Out-NA3.
Connect to ground when SEL = L.
Output P-Channel gate drivers for channel A
Output N-Channel gate drivers for channel A
Logic input control for channel B. When SEL = L, the pin is POSB.
When SEL = H, the pin is POS1B.
Logic input control for channel B. When SEL = L, the pin is NEGB.
When SEL = H, the pin is NEG1B.
Logic input control for channel B. When SEL = L, the pin is
HVEN1B. When SEL = H, the pin is POS2B.
Logic input control for channel B. When SEL = L, the pin is
HVEN2B. When SEL = H, the pin is NEG2B.
Used with SEL = H. Logic input control for Out-PB3 and Out-NB3.
Connect to ground when SEL = L.
Logic input select. See truth tables for SEL = L and SEL = H.
Logic input enable control. When EN = L, all P-channel output
drivers are high and all N-channel output drivers are low.
Output P-Channel gate driver for channel B
Output N-Channel gate driver for channel B
