PIN FUNCTIONS

N.

Name

Function

1

T1

Timer capacitor; the capacitor defines the time for the channel 1 shut down, after overload of

the external MOS transistor has been detected.

Supply Voltage.

4

T2

Timer capacitor; the capacitor defines the time for the channel 2 shut down, after overload of

the external MOS transistor has been detected.

5

PR

Programming resistor for overload detetcion threshold; the resistor from this pin to ground

defines the drain pin current and the charging of the timer capacitor.

6

IN3

Input 3; equal to IN1.

7

IN2

Input 2; equal to IN1.

8

IN1

Input 1; logic signal applied to this pin controls the driver 1; this pin features a current source to

assure defined high status when the pin is open.

9

EN

Enable logic signal high on this pin enables all channels

10

GND

Ground

11

G3

Gate 3 driver output; current source from CP or ground

12

G2

Gate 2 driver output; current source from CP or ground

14

S2

Source 2 sense input; monitors the source voltage.

15

S1

Source 1 sense input; monitors the source voltage.

16

G1

Gate 1 driver output; current source from CP or ground

17

D2

Drain 2 sense input; a programmable input bias current defines the drop across the external

19

D1

Drain 1 sense input; a programmable input bias current defines the drop across the external

20

CP

Charge pump capacitor; a alternating current source at this pin charges the connected

to charge all the three gates of the power MOS transistors.
