FUNCTION
PIN NUMBER NAME
Enable input: (EN biased LOW disables output regardless of Input state, EN biased
1 EN I high or floating enables output, EN is allowed to float hence it is pin-to-pin compatible
with TPS282X N/C pin)
2 GND - Ground: All signals referenced to this pin.
IN- I Input: Inverting input in the UCC27518, output held LOW if IN- is unbiased or floating
3
Input: Non-inverting input in the UCC27519, output held LOW if IN+ is unbiased or
IN+ I
floating
4 OUT O Sourcing and sinking current output of driver.
5 VDD i Supply input.
