Description

1

A0/F0

Logic Control Input (A0). See Table 11.

Decoder Pin (F0). This pin is used together with the specific fault pin (SF) to indicate which input is in a fault

condition. See Table 12.

2

EN/F2

Active High Digital Input (EN). When this pin is low, the device is disabled and all switches are off. When this pin is

high, the Ax logic inputs determine the on switches.

Decoder Pin (F2). This pin is used together with the specific fault pin (SF) to indicate which input is in a fault

condition. See Table 12.

3

Most Negative Power Supply Potential.

4

S1A

Overvoltage Protected Source Terminal 1A. This pin can be an input or an output.

5

S2A

Overvoltage Protected Source Terminal 2A. This pin can be an input or an output.

6

S3A

Overvoltage Protected Source Terminal 3A. This pin can be an input or an output.

7

S4A

Overvoltage Protected Source Terminal 4A. This pin can be an input or an output.

8

DA

Drain Terminal A. This pin can be an input or an output.

9

NEGFV

Negative Fault Voltage. This pin is the negative supply voltage that determines the overvoltage protection level. If

10

SF

Specific Fault Digital Output. This pin has a high output (weak internal pull-up resistor, nominally 3 V output) when

the device is in normal operation, or a low output when a fault condition is detected on a specific pin, depending

on the state of F0, F1, and, F2 as shown in Table 12.

11

FF

Fault Flag Digital Output. This pin has a high output when the device is in normal operation, or a low output when

a fault condition occurs on any of the Sx inputs. The FF pin has a weak internal pull-up resistor that allows multiple

signals to be combined into a single interrupt for larger modules that contain multiple devices.

12

POSFV

Positive Fault Voltage. This pin is the positive supply voltage that determines the overvoltage protection level. If a

13

DB

Drain Terminal B. This pin can be an input or an output.

14

S4B

Overvoltage Protected Source Terminal 4B. This pin can be an input or an output.

15

S3B

Overvoltage Protected Source Terminal 3B. This pin can be an input or an output.

16

S2B

Overvoltage Protected Source Terminal 2B. This pin can be an input or an output.

17

S1B

Overvoltage Protected Source Terminal 1B. This pin can be an input or an output.

18

Most Positive Power Supply Potential.

19

GND

Ground (0 V) Reference.

20

A1/F1

Logic Control Input (A1). See Table 11.

Decoder Pin (F1). This pin is used together with the specific fault pin (SF) to indicate which input is in a fault

condition. See Table 12.
