The maximum operating frequency of the IR21844STRPBF is 500 kHz, but it can be operated up to 1 MHz with reduced performance.
To ensure the bootstrap capacitor is properly charged, make sure to provide a low-impedance path to the bootstrap capacitor, and use a capacitor with a low equivalent series resistance (ESR).
The recommended dead time for the IR21844STRPBF is typically around 100-200 ns, but this can vary depending on the specific application and switching frequency.
The UVLO feature is enabled by default, and it will shut down the device if the VCC voltage falls below 10.5 V. To handle UVLO, ensure that the VCC voltage is above 10.5 V, or disable UVLO by tying the UVLO pin to VCC.
The maximum allowable voltage on the LO pin is 15 V, but it's recommended to keep it below 12 V to ensure reliable operation.
