Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 EN I Enable input. When the EN pin is biased LOW, the output is disabled regardless of input state. When the EN pin is biased high or left floating, the output is enabled. The EN pin is allowed to float because it is pin-to-pin compatible with the NC pin of the TPS282x device.
2 GND — Ground. All signals are referenced to this pin.
3 IN– (UCC27518A-Q1) I Input. This pin is the inverting input in the UCC27518A-Q1 device. The output is held LOW if the IN– pin is unbiased or floating.
IN+ (UCC27519A-Q1) I Input. This pin is the noninverting input in the UCC27519A-Q1 device. The output is held LOW if the IN+ pin is unbiased or floating.
4 OUT O Sourcing and sinking current output of driver.
5 VDD I Supply input.
