Description

1

IN1/F1

Logic Control Input (IN1) (See Table 8.)

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 9).

2

IN2/F2

Logic Control Input (IN2) (See Table 8).

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 9).

3

S1A

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

4

D1

Drain Terminal 1. This pin can be an input or an output.

5

S1B

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

6

S2B

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

7

D2

Drain Terminal 2. This pin can be an input or an output.

8

S2A

Overvoltage Protected Source Terminal 2A. 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 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 9.

The SF pin has a weak internal pull-up resistor, nominally 3 V output.

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

S3A

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

14

D3

Drain Terminal 3. 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

Most Negative Power Supply Potential.

17

Most Positive Power Supply Potential.

18

GND

Ground (0 V) Reference.

19

EN/F0

Active Low Digital Input. When this pin is high, the device is disabled and all switches are off. When this pin is low,

the INx logic inputs determine the on switches.

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 9).

20

IN3

Logic Control Input (See Table 8).
