Description
Output 7. This pin provides connection to drain of output MOSFET number seven.
Output 6. This pin provides connection to drain of output MOSFET number six.
System Clock. This pin clocks the internal Shift registers of the 33291.
Serial Input. This pin is for the input of serial instruction data. SI information is read on the falling edge
of SCLK.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Serial Output. This pin is the tri-stateable output from the Shift register.
Chip Select. Whenever this pin is in a logic low state, data can be transferred from the MCU to the 33291
through the SI pin and from the 33291 to the MCU through the SO pin.
Output 5. This pin provides connection to drain of output MOSFET number five.
Output 4. This pin provides connection to drain of output MOSFET number four.
Output 3. This pin provides connection to drain of output MOSFET number three.
Output 2. This pin provides connection to drain of output MOSFET number two.
Short Fault Protect Disable. This pin is used to prevent the outputs from latching-OFF because of an
over current condition.
Logic Supply.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path.
Output MOSFET Gate Drive Supply.
RESET. This pin is active low. It is used to clear the SPI Shift register, thereby setting all output switches
OFF.
Output 1. This pin provides connection to drain of output MOSFET number one.
Output 0. This pin provides connection to drain of output MOSFET number zero.
