The Broadcom HCPL-316J-500E is an optically isolated IGBT and MOSFET gate-drive optocoupler with integrated desaturation fault detection and fault feedback, supplied in a 16-pin SOIC measuring 10.312mm x 7.493mm on tape and reel at 850 pieces per reel. It delivers 2A output current, 2.5A maximum, at up to 30V output voltage, and runs from a 4.5V to 5.5V supply. Switching figures are 500ns propagation delay, 300ns turn-on and 320ns turn-off delay, 100ns rise and fall times and 300ns pulse-width distortion. The record lists 5kV isolation voltage with CSA, EN, IEC and UR approvals, a 1.2W power dissipation limit, 16mA forward current at 1.5V, and a -40C to 100C ambient range with a 125C maximum junction temperature. Two record notes on the HCPL-316J-500E: the product name states 1500V while the Isolation Voltage attribute reads 5kV, and REACH SVHC reads Yes.

Isolated gate drivers with desaturation detection sit between a low-voltage controller and the high-side switch of a power-conversion stage, providing both galvanic isolation and short-circuit protection. Typical applications are motor drives and servo inverters, solar and wind inverters, uninterruptible power supplies, induction heating, welding equipment, EV chargers and traction converters. The desaturation input monitors the collector-emitter voltage of the IGBT and shuts the gate down through a controlled soft turn-off if the device leaves saturation, then reports the event back across the barrier on the fault pin so the controller can latch the fault. That protection loop is why designers pick a part like the HCPL-316J-500E over a plain isolated driver. Buyers are industrial drive, renewable-energy and power-electronics OEMs, where the safety approvals listed on the record are usually a certification requirement rather than a preference.
