The IRS21091SPBF is an advanced high-side and low-side driver IC (integrated circuit) component designed for driving MOSFETs (metal-oxide-semiconductor field-effect transistors) and IGBTs (insulated-gate bipolar transistors) in various power electronics applications. It provides high-performance and efficient switching capabilities for precise control of power delivery.
Key Features:
1. High-Voltage Level Shifting: The IRS21091SPBF features two independent high- and low-side channels with a high-voltage level shifting capability. This enables the device to directly drive both high-side and low-side power devices, eliminating the need for external level-shifting components.
2. Integrated Bootstrap Function: The IC incorporates an integrated bootstrap function that simplifies the use of high-side drivers by generating the required high voltage for driving the high-side MOSFET or IGBT. This feature eliminates the need for external bootstrap diodes and capacitors, reducing the overall component count and improving system reliability.
3. Adjustable Deadtime Control: The device offers adjustable deadtime control, allowing precise control of the time interval between the turn-off of the low-side device and the turn-on of the high-side device. This feature helps prevent shoot-through current during the switching transitions, enhancing overall system efficiency and preventing device failures.
4. Undervoltage and Overvoltage Lockouts: The IRS21091SPBF incorporates undervoltage and overvoltage lockout protections, ensuring safe device operation
