10 / 33 page UCC27511 UCC27512 SLUSAW9D – FEBRUARY 2012 – REVISED MAY 2013 www.ti.com Table 3. UCC27511 TERMINAL FUNCTIONS TERMINAL I/O FUNCTION PIN NUMBER NAME 1 VDD I Bias supply input. Sourcing current output of driver. Connect resistor between OUTH and Gate of 2 OUTH O power-switching device to adjust turnon speed. Sinking current output of driver. Connect resistor between OUTL and Gate of 3 OUTL O power-switching device to adjust turnoff speed. 4 GND - Ground: All signals referenced to this pin. Inverting input: When the driver is used in non-inverting configuration, connect IN- 5 IN- I to GND in order to enable output, OUT held LOW if IN- is unbiased or floating Non-inverting input: When the driver is used in inverting configuration, connect IN+ 6 IN+ I to VDD in order to enable output, OUT held LOW if IN+ is unbiased or floating Table 4. UCC27512 TERMINAL FUNCTIONS TERMINAL I/O FUNCTION PIN NUMBER NAME 1 IN+ I Non-inverting 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 non-inverting configuration, connect IN- to GND in order to enable output, OUT held LOW if IN- is unbiased or floating.
