Use DC nested sweep in PSpice for TI to determine the output voltage characteristics of a MOSFET circuit. Watch Video 2:12 DC Bias Point Analysis | PSpice Tutorial Videos Learn how to perform DC Bias Point analysis in PSpice for TI using a diode limiter circuit as an example. ...
To use a MOSFET as a switch, you need to ensure that the gate-source voltage (Vgs) is higher than the source voltage. When the gate is connected to the source (Vgs=0), the MOSFET remains off. Take the IRFZ44N, a “standard” MOSFET, as an example. This MOSFET only turns on when ...

Safety and protection: The MAX32626 controls an on-board isolated gate driver, ADuM4120, that drives an N-FET connected to an external contactor (which sits on the battery board, for example). This has a protection function as the MCU will switch the MOSFET on and...
Turn-off losses inherently depend on the device itself (as opposed to turn-on switching losses, which can depend on the reverse recovery charge of an external silicon or SiC diode, as in BOOST converters and many other topologies), ...
Every PCB design tool has a set of rules (DRC/DFM) meant to avoid these issues, also known as near field effects. Modern SMD devices are realized with packages that drastically reduce proximity effects, thus allowing to use small spacing between components on a PCB layer. In so...
Recall that an inductor is a passive electronic component that can store electrical energy in the form of magnetic energy. We can use this property to control the output voltage of our circuit. Here is how it works: If we OPEN the switch, as shown in the “Boost switch OFF State” diagr...
This can become a problem if the DC resistance of the load coil is high. To combat this one may wish to use a larger capacitor than inductor, since a metalized polyester capacitor’s parasitic resistance tends to be smaller than a large coil’s. ...
As its operating voltage is from 1.65 V to 5 V, it allows a mixed mode where the designer can use 1.8 V, 2.5 V, or 3.3 V. The SN74LVCxG logic family input structure is 3.3-V CMOS DC; VIL and VIH fixed levels of 0.8 V and 2 V meet LVTTL, meaning that the threshold voltage ...
The MOSFET effect on the gate-driver IC, or a pulse- width modulation (PWM) controller with an integrated gate driver, add to the power-dissipation losses. As shown by Equation 6, gate-drive losses do not all occur on the MOSFET. PDRV = VG _ DRV × QG(tot) × fS 2 × ...
