Pin Functions - UCC27511

PIN I/O DESCRIPTION
NO. NAME
1 VDD I Bias supply input.
2 OUTH O Sourcing current output of driver. Connect resistor between OUTH and Gate of power-switching device to adjust turnon speed.
3 OUTL O Sinking current output of driver. Connect resistor between OUTL and Gate of power-switching device to adjust turnoff speed.
4 GND - Ground: All signals referenced to this pin.
5 IN- I Inverting input: When the driver is used in noninverting configuration, connect IN- to GND in order to enable output, OUT held LOW if IN- is unbiased or floating
6 IN+ I Noninverting input: When the driver is used in inverting configuration, connect IN+ to VDD in order to enable output, OUT held LOW if IN+ is unbiased or floating

Pin Functions - UCC27512

PIN I/O DESCRIPTION
NO. NAME
1 IN+ I Noninverting input: When the driver is used in inverting configuration, connect IN+ to VDD in order to enable output, OUT held LOW if IN+ is unbiased or floating.
2, 5 GND - Ground: All signals referenced to this pin. TI recommends to connect pin 2 and pin 5 on PCB as close to the device as possible.
3 VDD I Bias supply input.
4 OUT O Sourcing/sinking current output of driver.
6 IN- I Inverting input: When the driver is used in noninverting configuration, connect IN- to GND in order to enable output, OUT held LOW if IN- is unbiased or floating.
