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.
