Thereforewhile connecting mosfetsin parallel we do not have to worry much about anything, and you may simply go ahead hooking them up in parallel, without depending on any current limiting resistors, as shown below. However using separate gate resistors for each of the mosfets should be considere...
The potential increase of the MOSFET temperature is determined by its thermal resistance. Thermal resistance is expressed in °C/W. It indicates the increase in temperature compared to the power dissipated on the MOSFET. In the datasheet, you’ll often find the parameters, RthJCand RthJA. RthJC...

Total power dissipation for the linear charger can be expressed as below.Pdiss = (Vin - Vbatt) × Icharge To decide the fast charging current, we need to calculate the worst-case allowable power dissipation on the P-MOSFET Q1. Power dissipation on the Q1 is expressed as below:Pdiss(Q1)...
Equation 3 is used to calculate VOUT for Figure 1. VOUT = Gd × ILOAD× RSENSE + Vcm × Gcm The overall error for measuring current would be greater than 5% when using 1% resistors for R1 to R4 and calculating the errors with worst-case tolerances. As a result, there...

Comparing IGTB with power MOSFETs The insulated-gate bipolar transistor features a voltage drop which is significantly low when compared to a conventional MOSFET in the devices which have a voltage of higher blocking. The n-drift region’s depth must also increase along with an increase in the ...
As a SW element, it is a device such as Si MOSFET and SiC MOSFET that does not have a defined short circuit tolerance.・Regarding the DESAT voltage, check the current value equivalent to the DESAT threshold voltage from the I-V characteristic graph of the SW element, Is it o...
As shown by Equation 6, gate-drive losses do not all occur on the MOSFET. PDRV = VG _ DRV × QG(tot) × fS 2 × RGHI RGHI + RG + RGI + RGLO RGLO + RG + RGI where: (6) • PDRV is the total gate drive loss divided to calculate the ...
