This pin provides connection to drain of output MOSFET number seven.
This pin provides connection to drain of output MOSFET number six.
This pin clocks the internal Shift registers of the 33298.
This pin is for the input of serial instruction data. SI information is read on the falling edge of
SCLK.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin is the tri-stateable output from the Shift register.
Whenever this pin is in a logic low state, data can be transferred from the MCU to the 33298
through the SI pin and from the 33298 to the MCU through the SO pin.
This pin provides connection to drain of output MOSFET number five.
This pin provides connection to drain of output MOSFET number four.
This pin provides connection to drain of output MOSFET number three.
This pin provides connection to drain of output MOSFET number two.
This pin is used to prevent the outputs from latching-OFF because of an over current
condition.
Logic Supply.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Output MOSFET gate drive supply.
This pin is active low. It is used to clear the SPI Shift register, thereby setting all output
switches OFF
