The typical supply voltage range is 10–20 V, as indicated in the directory reference. However, the exact range depends on the specific model and application. Always consult the datasheet or the manufacturer to confirm the required supply voltage for your design.
UVLO prevents the gate driver from operating when the supply voltage is too low, typically below 8–9 V. This ensures that the power transistor is not driven with insufficient gate voltage, which could cause it to operate in the linear region and lead to excessive power dissipation or damage.
Some gate driver ICs include isolation barriers that can withstand isolation voltages from 1500 to 5000 Vrms. This isolation protects low-voltage control circuitry from high-voltage transients on the power side. The exact isolation rating and CMTI (common-mode transient immunity) must be verified with the manufacturer for the specific model.
The propagation delay (typically 50–200 ns) and rise/fall times (typically 10–50 ns) determine how quickly the gate can be charged and discharged, which in turn affects the maximum switching frequency. Faster times allow higher frequencies, but the actual limit also depends on the power transistor and circuit layout.
