Overview
The
intelligent power switch (IPS), which features overcurrent and
overtemperature protection for safe output load control. The
also offers the quick activation of its
output stage even at power-up. In fact, the input to the output propagation delay at startup is guaranteed ≤ 60 µs.
The board is designed to meet the application requirements for the galvanic isolation between the user and power
interfaces.
An optical isolation satisfies this requirement. The isolation is implemented through five optocouplers (ISO1,
ISO2, ISO3, ISO4, and ISO5) for the input signal forward to the device, the FLT diagnostic feedback signals of
the device, and two additional signals for safety application optimization (Nch-DRV for the fast discharge control
of the output voltage, and OUT_FB for the on/off status monitoring of the output stage).
The expansion board features:
•
