AUIRS21814S Frequently Asked Questions (FAQs)
-
Infineon provides a recommended PCB layout in the application note AN2014-01, which includes guidelines for thermal vias, copper thickness, and component placement to ensure optimal thermal performance.
-
The selection of a gate driver depends on the specific application requirements. Infineon recommends using a gate driver with a high current capability, such as the 2EDN7524F or the 1EDN8555F, and ensuring that the driver's output voltage is compatible with the AUIRS21814S's gate-source voltage rating.
-
According to Infineon's application note AN2014-01, the maximum allowed voltage imbalance between the high-side and low-side FETs is ±5V to ensure reliable operation and prevent damage to the device.
-
Infineon recommends using an external overcurrent protection circuit, such as a sense resistor and a comparator, to detect overcurrent conditions. The application note AN2014-01 provides a reference design for overcurrent protection.
-
The recommended dead time for the AUIRS21814S in a half-bridge configuration is typically in the range of 100-200 ns, depending on the specific application requirements and the switching frequency. A longer dead time can help prevent shoot-through currents, but may also increase switching losses.
