High-speed optocoupler for isolated gate drive and industrial comms
The RV1S9262ACCSP-10YV#KC0: Single-channel high-speed optocoupler with push-pull, totem-pole output, rated for 15Mbps data rate and 5000Vrms isolation.
60ns propagation delay and 100kV/µs CMTI — what they mean for the drive circuit
The 60ns max propagation delay (tpLH / tpHL) keeps signal skew low enough for dead-time control in hard-switched inverter stages. The 100kV/µs common-mode transient immunity ensures the output doesn't glitch when the IGBT collector swings several hundred volts in a few nanoseconds — a common failure point in motor drives and UPS systems. The push-pull output sources and sinks 25 mA, enough to drive a standard gate resistor directly.
