Function
T6819: ground; reference potential; internal connection to Pin 9 and Pin 16; cooling tab
T6829: Additional connection to heat slug
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
Low-side driver output 3; see Pin 2
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
Chip select input; 5-V CMOS logic level input with internal pull up;
low = serial communication is enabled, high = disabled
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
Serial clock input; 5-V CMOS logic level input with internal pull down;
controls serial data input interface and internal shift register (f
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
Ground; see Pin 1
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.
