Pin Description SO28

Pin

Symbol

Function

1, 2

OUT5

Half-bridge output 5; formed by internally connected power MOS high-side switch 5 and low-

side switch 5 with internal reverse diodes; short circuit protection; overtemperature protection;

diagnosis for short and open load

3, 4

OUT4

Output 4; see pin 1

5

VS

Power supply output stages HS4, HS5, HS6, internal supply; external connection to pin 10

necessary

6, 7, 8, 9

GND

Ground; reference potential; internal connection to pins 20 to 23; cooling tab

10

VS

Power supply output stages HS1, HS2 and HS3

11, 12

OUT3

Output 3; see pin 1

13, 14

OUT2

Output 2; see pin 1

15, 16

OUT1

Output 1; see pin 1

17

INH

Inhibit input, 5V logic input with internal pull down, low = standby, high = normal operation

18

DO

Serial data output, 5V CMOS logic level tri-state output for output (status) register data, sends

16-bit status information to the microcontroller (LSB is transferred first). Output will remain tri-

stated unless device is selected by CS = low; therefore, several ICs can operate on one data

output line only

19

VCC

Logic supply voltage (5V)

20, 21,

22, 23

GND

Ground, see pins 6 to 9

24

CS

Chip select input, 5V CMOS logic level input with internal pull up;

low = serial communication is enabled, high = disabled

25

CLK

Serial clock input, 5V CMOS logic level input with internal pull down,

26

DI

Serial data input; 5V CMOS logic level input with internal pull down; receives serial data from

the control device; DI expects a 16-bit control word with LSB being transferred first
