Related Q&A Q1: What is the maximum supply voltage for the IRS2104STRPBF? A1: The IRS2104STRPBF can operate with a maximum supply voltage of 20V for its high-side and low-side driver functionality. Q2: Can the IRS2104 drive both N-channel and P-channel MOSFETs? A2: The IRS2104 is primarily designed to drive N-channel MOSFETs and IGBTs. For P-channel MOSFETs, additional circuit considerations would be necessary. Q3: What is the significance of the “floating high-side driver” feature in the IRS2104? A3: The floating high-side driver allows the IRS2104 to control the gate of a high-side MOSFET with a source terminal that is not connected to ground, making it suitable for half-bridge configurations where the high-side switch needs to operate above the supply voltage. Q4: How does the IRS2104 prevent cross-conduction? A4: The IRS2104 includes built-in features such as dead-time management to ensure that both high-side and low-side drivers are not turned on simultaneously, thereby preventing shoot-through and cross-conduction between the devices. Q5: In which types of applications would you typically use the IRS2104? A5: The IRS2104 is commonly used in applications involving motor control (like BLDC motors), power inverters for renewable energy systems, switched-mode power supplies, and other industrial automation applications requiring precise control of power devices.
