L6385D013TR

L6385D013TR Description

The L6385D013TR from STMicroelectronics is a high-voltage, half-bridge gate driver IC designed for robust power management applications. This obsolete surface-mount device operates with a maximum supply voltage of 17V and supports bootstrap voltages up to 600V, making it suitable for driving high-side MOSFETs or IGBTs in demanding environments. With two independent channels, it provides inverting logic inputs (VIL = 1.5V, VIH = 3.6V) and delivers peak output currents of 400mA (source) and 650mA (sink), ensuring efficient switching of power transistors. The fast switching characteristics (50ns rise, 30ns fall times) minimize switching losses, enhancing system efficiency. Packaged in 8SO and supplied in tape & reel (TR), it is ideal for automated assembly processes.
