IR2104 Half Bridge Driver SMD IC

IR2104 Half Bridge Driver SMD IC

The IR2104 is a half-bridge driver IC designed to control high- and low-side MOSFETs or IGBTs in a half-bridge configuration. This integrated circuit is ideal for use in motor drives, switch-mode power supplies (SMPS), inverters, and other high-power switching applications. It is available in an SMD package, making it suitable for compact and high-density circuit designs. Key features of the IR2104 include its dual-channel output, which can drive both the high-side and low-side MOSFETs or IGBTs. The driver operates with a single supply voltage ranging from 10V to 20V, and it includes bootstrap circuitry that allows it to generate a floating voltage for driving the high-side MOSFET or IGBT. This is essential for efficient switching in power conversion circuits. The IC is designed to handle high-speed switching and can provide peak output currents of up to 2A for both high-side and low-side outputs. The IR2104 also features under-voltage lockout (UVLO) protection, which ensures that both the high-side and low-side drivers are only enabled when the voltage is above a certain threshold, preventing malfunction due to low supply voltages. Additionally, the device offers desaturation detection, providing protection against overcurrent conditions in the power switches.
