N-channel 80 V, 1.9 mOhm ASFET with enhanced dynamic current sharing in LFPAK88
In high-power applications, it is common practice to connect two or more MOSFETs in parallel to provide high current capability. Even when the gates are driven from the same gate driver, it can be challenging to ensure that MOSFETs share the load current equally.
Small differences in VGS(th) for individual devices cause the MOSFET with the lowest VGS(th) to turn-on first, taking a larger share of the load current during the dynamic switching phase.
The difference in load current between individual MOSFETs ΔID can be significant often leading to differential heating and potential accelerated failure.
One method to reduce the ΔI between MOSFETs is to select devices with matched VGS(th), but testing & sorting MOSFETs with matched VGS(th) can be a difficult process. VGS(th) is typically measured at ΔID < 1 mA and is influenced by temperature also.
ASFETs with enhanced dynamic current sharing are designed to show significantly improved current sharing with low ΔID when connected in parallel applications, they also deliver improved temperature stability showing lower ΔID due to temperature differences across the PCB.
