IC GATE DRVR HI/LOW SIDE 14DIP
Hello everyone, welcome to the new post today. The IR2112 is a high voltage IC that acts as a MOSFET driver and IGBT driver. This article mainly introduces circuit, pinout, datasheet, and other detailed information about Infineon Technologies IR2112.
IR2112
The IR2112 is a high voltage IC that acts as a MOSFET driver and IGBT driver. It has independent high and low-side referenced output channels with a threshold voltage of 600 V.
Bootstrap feature makes it compatible with high-side driver applications. Additionally, it has Schmitt triggered inputs that are compatible with the standard CMOS and LSTTL outputs. The voltage range is 10V to 20V.
Furthermore, it has applications that require the circuitry of both high and low-side drive, for example, half-bridge and full-bridge circuits. It is available in 14 Lead PDIP and 16 lead SOIC packages.
