Bootstrap Circuitry Selection for Half Bridge Configurations
www.ti.comWhen the low-side FET is turned off and the high-side is on, the HS pin of the gate driver and the switch node are pulled to the high voltage bus HV; the bootstrap capacitor discharges some of the stored voltage (accumulated during the charging sequence) to the high-side FET through the HO and HS pins of the gate driver as shown in Figure 2 ...
Power MOSFET Basics
www.aosmd.commainly used for <200V voltage rating due to their higher channel density and thus lower on-resistance. Planar MOSFETs are good for higher voltage ratings since on-resistance is dominated by epi-layer resistance and high cell density is not beneficial. The basic MOSFET operation is the same for both structures. Unless specified, the N-channel

The FET Constant-Current Source/Limiter
www.vishay.comThe FET Constant-Current Source/Limiter Introduction The combination of low associated operating voltage and high output impedance makes the FET attractive as a constant-current source. An adjustable-current source (Fig-ure 1) may be built with a FET, a variable resistor, and a small battery. For optimum thermal stability, the FET should
MT-037: Op Amp Input Offset Voltage - Analog Devices
www.analog.comzero volts. In practice, a small differential voltage must be applied to the inputs to force the output to zero. This is known as the input offset voltage, VOS. Input offset voltage is modeled as a voltage source, VOS, in series with the inverting input terminal of the op amp as shown in Figure 1. Rev.0, 10/08, WK Page 1 of 10 z z z z z z z

Use of a floating supply be-tween the resistor junction and the FET gate will over-come this problem. The circuit is shown in Figure 7 and allows the gate control voltage to be the same value as that voltage used without a feedback circuit, while preserving
