FAQ

How is the over-current protection fault output pulse width determined?

The fault output pulse width (tFO) can be fixed at a minimum of 20µs or adjusted by connecting a capacitor (CCF) to the VCF pin. The duration is calculated using the formula tFO = -(1MΩ*CCF)*ln(1-VCF+/5V) + 100ns + 20us(min.).

What triggers the over-temperature protection mechanism?

Over-temperature protection is triggered when the internal LVIC temperature exceeds the trip level (OTT), typically between 110°C and 150°C depending on conditions. This causes all low-side MOSFETs to turn off and generates a fault signal until the temperature drops below the reset level.

Can the VCF pin be used to enable or disable the module?

Yes, the VCF pin provides an enable functionality. When held high, the IPM operates normally. If pulled low, it shuts down all low-side MOSFETs until the enable condition is restored, allowing for external control of the module's operational state.
