MOSFET/IGBT driver eliminates need for a negative gate driver

The 1V-maximum low-level output voltage in the VO3150 0.5A MOSFET/IGBT driver eliminates the need for a negative gate driver. Combining a high-speed optocoupler and an IGBT (integrated-gate-bipolar-transistor)/MOSFET driver in one package, this isolated device suits direct driving of IGBTs with 1200V and 50A ratings in industrial and consumer applications. Features include a 5300V-rms isolated voltage; minimum and typical common-mode rejection of 15 and 30 kV/µsec, respectively; and a 1500V common-mode voltage. Available in a DIP-8 package, the VO3150 costs $1.93 (10,000).
