8.3.1.5 OUT

OUT is the output of a high-current power driver capable of driving the gate of a power MOSFET with peak currents exceeding ±750 mA (up to ±1 A). OUT is actively held low when VCC is below the UVLO threshold. This feature eliminates the need for a gate-to-source bleeder resistor associated with the MOSFET gate drive.

The high-current power driver consists of CMOS FET output devices, which can switch all of the way to GND and all of the way to VCC. The output provides very smooth rising and falling waveforms, providing very low impedances to overshoot and undershoot which means that in many cases, external Schottky clamp diodes may not be necessary on the output. Finally, no external gate voltage clamp is necessary with the UCC2813-x-Q1 as the on-chip Zener diode automatically clamps the output to VCC.
