TERMINAL FUNCTIONS (UCC27516)
TERMINAL I/O
FUNCTION
PIN NUMBER NAME
Inverting Input: When the driver is used in non-inverting configuration, connect IN-
1 IN- I
to GND in order to enable output, OUT held LOW if IN- is unbiased or floating.
Ground: All signals referenced to this pin. TI recommends to connect pin 2 and pin 3
2, 3 GND -
on PCB as close to the device as possible.
4 VDD I Bias supply input.
5 OUT I Sourcing/Sinking Current Output of Driver
Non-Inverting Input: When the driver is used in inverting configuration, connect IN+
6 IN+ O
to VDD in order to enable output, OUT held LOW if IN+ is unbiased or floating.
