2 Wide Supply Voltage Range

The wide supply voltage range of the UCC27614, (4.5 V to 26 V) is optimized to source/sink high peak current to drive high gate charge MOSFETs as shown on Figure 2-1 and Figure 2-2. The UCC27614’s wide drive voltage and high peak current can also be beneficial to drive IGBTs, which have higher threshold voltages and larger gate capacitance than Si MOSFETs. The 26 V maximum recommended operating voltage provides sufficient margin against transients resulting from high di/dt in the gate drive loops coupled with parasitic inductance from PCB traces in fast switching applications.
