Definition
1
OP7
Output 7
Connection to drain of output MOSFET number seven.
2
OP6
Output 6
Connection to drain of output MOSFET number six.
3
SCLK
System Clock
Clocks the internal Shift registers of the 33291.
4
SI
Serial Input
This pin is for the input of serial instruction data. SI information is read on the falling
edge of SCLK.
5 – 8, 17 – 20
GND
Ground
Connection to IC Power Ground and functions as part of heat sinking path.
9
SO
Serial Output
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
Connection to drain of output MOSFET number five.
12
OP4
Output 4
Connection to drain of output MOSFET number four.
13
OP3
Output 3
Connection to drain of output MOSFET number three.
14
OP2
Output 2
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 overcurrent
condition.
16
V
DD
Logic Supply
Plus supply for logic.
21
V
PWR
Output MOSFET
Gate Drive Supply
Main power 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
Connection to drain of output MOSFET number one.
24
OP0
Output 0
Connection to drain of output MOSFET number zero.
