3 Description

The ISO5500 is an isolated gate driver for IGBTs and MOSFETs with power ratings of up to IC = 150 A and
VCE = 600 V. Input TTL logic and output power stage are separated by a capacitive, silicon dioxide (SiO2), isolation barrier. When used in conjunction with isolated power supplies, the device blocks high voltage, isolates ground, and prevents noise currents from entering the local ground and interfering with or damaging sensitive circuitry.

The device provides over-current protection (DESAT) to an IGBT or MOSFET while an Undervoltage Lockout circuit (UVLO) monitors the output power supply to ensure sufficient gate drive voltage. If the output supply drops below 12 V, the UVLO turns the power transistor off by driving the gate drive output to a logic low state.

For a DESAT fault, the ISO5500 initiates a soft shutdown procedure that slowly reduces the IGBT/MOSFET current to zero while preventing large di/dt induced voltage spikes. A fault signal is then transmitted across the isolation barrier, actively driving the open-drain FAULT output low and disabling the device inputs. The inputs are blocked as long as the FAULT-pin is low. FAULT remains low until the inputs are configured for an output low state, followed by a logic low input on the RESET pin.

The ISO5500 is available in a 16-pin SOIC package and is specified for operating temperatures from –40°C to 125°C.
