Pin Description

Pin

Symbol

Function

1GND

T6819: ground; reference potential; internal connection to pin 9 and pin 16; cooling tab

T6829: additional connection to heat slug

2

OUT1L

Low-side driver output 1; power MOS open drain with internal reverse diode; short-circuit protection;

overtemperature protection; diagnosis for short and open load; PWM ability

3

OUT3L

Low-side driver output 3; see pin 2

4

OUT3H

High-side driver output 3; power MOS open source with internal reverse diode; short-circuit protection;

overtemperature protection; diagnosis for short and open load; PWM ability

5

CS

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

low = serial communication is enabled, high = disabled

6

DI

Serial data input; 5-V 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

7

CLK

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

controls serial data input interface and internal shift register (f

8

PWM

PWM input; 5-V CMOS logic level input with internal pull down; receives PWM signal to control outputs

which are selected for PWM mode by the serial data interface, high = outputs on, low = outputs off

9

GND

Ground; see pin 1

10

DO

Serial data output; 5-V CMOS logic-level tristate output for output (status) register data; sends 16-bit

status information to the microcontroller (LSB is transferred first); output will remain tristated unless

device is selected by CS = low, therefore, several ICs can operate on one data-output line only.

VS

Power supply for high-side output stages OUT1H, OUT2H, OUT3H, internal supply

13

OUT1H

High-side driver output 1; see pin 4

14

OUT2H

High-side driver output 2; see pin 4

15

OUT2L

Low-side driver output 2; see pin 2
