Description

The ISO5500DW is a 2.5A isolated IGBT/MOSFET Gate Driver features 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 Under-voltage Lockout circuit (UVLO) monitors the output power supply to ensure sufficient gate drive voltage. If the output supply drops below 12V, 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.
Capacitive isolated fault feedback
300ns Maximum propagation delay
Soft IGBT turnoff Integrated fail-safe IGBT protection
Under-voltage lockout (UVLO) protection with hysteresis
±50kV/µs Typical transient immunity
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
