Ground; reference potential; internal connection to pin 20-23; cooling tab
Inhibit input; 5V logic input with internal pull down; low = standby, high = normal operating
Function
Low-side driver output 5; Power-MOS open drain with internal reverse diode; short-circuit protection;
diagnosis for short and open load
High-side driver output 5; Power-MOS open drain with internal reverse diode; short-circuit protection;
diagnosis for short and open load
High-side driver output 4; see pin 2
Low-side driver output 4; see pin 1
Power supply output stages HS4, HS5, HS6, internal supply; external connection to pin 10 necessary
Power supply output stages HS1, HS2 and HS3
Low-side driver output 3; see pin 1
High-side driver output 3; see pin 2
High-side driver output 2; see pin 2
Low-side driver output 2; see pin 1
High-side driver output 1; see pin 2
Low-side driver output 1; see pin 1
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.
Logic supply voltage (5V)
Ground; see pin 6-9
Chip select input; 5V CMOS logic level input with internal pull up;
low = serial communication is enabled, high = disabled
Serial clock input; 5V CMOS logic level input with internal pull down;
controls serial data input interface and internal shift register (f
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
