IR2112STR

IR2112STR Description

The IR2112STR from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for driving MOSFETs and IGBTs in half-bridge or full-bridge configurations. This dual-channel driver features independent high-side and low-side outputs, supporting peak output currents of 250mA (source) and 500mA (sink). With a supply voltage range of 10V to 20V and a maximum bootstrap voltage of 600V, it is well-suited for high-power switching applications. The device offers fast switching performance, with typical rise and fall times of 80ns and 40ns, ensuring efficient power conversion.
