APPLICATION DESCRIPTION
Figure 8 illustrates a standard isolated MOSFET driver such Figure 9 illustrates the ability to do away with external as Vishay’s VO1263. Though these parts are generally turn-off circuitry with the VOM1271, by taking advantage of capable of supplying higher output current, they lack the VOM1271’s integrated turn-off circuitry. integrated fast turn-off circuitry. Thus, if high turn-off speed is required. external circuitry needs to be provided, as illustrated in figure one. 2 MΩ + Channel 1 P-channel Switch 1 control JFET N-channel – MOSFETs Fig. 9 - Typical MOSFET Driver Application without Integrated Fast Turn-Off Rev. 1.6, 07-Jan-14
