3 / 24 page MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA 33291 3 PIN FUNCTION DESCRIPTION Pin Pin Name Description 1OP7 Output 7. This pin provides connection to drain of output MOSFET number seven. 2OP6 Output 6. This pin provides connection to drain of output MOSFET number six. 3SCLK System Clock. This pin clocks the internal Shift registers of the 33291. 4SI Serial Input. This pin is for the input of serial instruction data. SI information is read on the falling edge of SCLK. 5GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 6GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 7GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 8GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 9SO Serial Output. This pin is the tri-stateable output from the Shift register. 10 CS 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. 11 OP5 Output 5. This pin provides connection to drain of output MOSFET number five. 12 OP4 Output 4. This pin provides connection to drain of output MOSFET number four. 13 OP3 Output 3. This pin provides connection to drain of output MOSFET number three. 14 OP2 Output 2. This pin provides connection to drain of output MOSFET number two. 15 SFPD Short Fault Protect Disable. This pin is used to prevent the outputs from latching-OFF because of an over current condition. 16 VDD Logic Supply. 17 GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 18 GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 19 GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 20 GND Ground. This pin provides connection to IC Power Ground and functions as part of heat sinking path. 21 VPWR Output MOSFET Gate Drive Supply. 22 RST RESET. This pin is active low. It is used to clear the SPI Shift register, thereby setting all output switches OFF . 23 OP1 Output 1. This pin provides connection to drain of output MOSFET number one. 24 OP0 Output 0. This pin provides connection to drain of output MOSFET number zero.
