Average Power Status
Fail · Pulse Check Required
At least one physical resistor exceeds 20% of its typical package rating. Increase package size or parallel count, or reduce drive energy.
Engineering Calculators
Gate Resistor Power and Stress Evaluator
Estimate gate resistor average power, pulse energy, peak stress, package margin, and parallel resistor sharing for power switch gate-drive design.
