Function
Ground; reference potential; internal connection to pin 7, 8 and 14; cooling tab
Half-bridge output 3; formed by internally connected power MOS high-side switch 3 and low-side switch 3
with internal reverse diodes; short-circuit protection; overtemperature protection; diagnosis for short and
open load
Power supply for output stages OUT1, OUT2 and OUT3, internal supply
Chip select input; 5V CMOS logic level input with internal pull up;
low = serial communication is enabled, high = disabled
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
Serial clock input; 5 V CMOS logic level input with internal pull down;
controls serial data input interface and internal shift register (f
Ground; see pin 1
Ground; see pin 1
Serial data output; 5V 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 tri-stated unless
device is selected by CS = low, therefore, several ICs can operate on only one data output line.
Inhibit input; 5V logic input with internal pull down; low = standby, high = normal operation
Logic supply voltage (5V)
