Function
Used only for final testing, to be connected to OUT3F
Half-bridge output 3; formed by internally connecting 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
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 transferred first
Serial clock input; 5V CMOS logic level input with internal pull-down;
controls serial data input interface and internal shift register (f
Serial data output; 5V CMOS logic-level tri-state output for output (status) register data; sends 16-bit status
information to the microcontroller (LSB transferred first); output will remain tri-stated unless device is
selected by CS = low; this allows several ICs to operate on only one data-output line
