The maximum operating frequency of the IRS2186STRPBF is 500 kHz, but it can be used up to 1 MHz with some limitations. However, it's recommended to consult with the application notes and design guidelines for specific use cases.
The bootstrap capacitor should be sized based on the maximum voltage and current requirements of the high-side driver. A general rule of thumb is to use a capacitor with a value of at least 10 times the high-side driver's peak current. Additionally, the capacitor's voltage rating should be at least 1.5 times the maximum voltage of the high-side driver.
To minimize EMI and noise, it's recommended to follow a compact layout with short traces and minimal loop areas. Place the IRS2186STRPBF close to the power MOSFETs, and use a solid ground plane to reduce radiation. Additionally, use shielding and filtering components, such as ferrite beads and capacitors, to further reduce EMI and noise.
To protect the IRS2186STRPBF from overvoltage and overcurrent conditions, use voltage clamping devices, such as TVS diodes, and current limiting resistors. Additionally, implement overvoltage and overcurrent detection circuits to shut down the device in case of fault conditions.
The recommended dead time between the high-side and low-side drivers is typically in the range of 10-50 ns, depending on the specific application and switching frequency. However, it's recommended to consult with the application notes and design guidelines for specific use cases.
