time profiles applied to the silicon substrate during oxide growth assures consistant preformance through the development of good transition regions between the oxide, the silicon below it, and thew polysilicon above it. In fact, this reduction is the reason for voltage reduction from 10 volts (standard MOSFETs) to 5 volts (Logic Level MOSFETs). Since the surface inversion of the MOS channel is determined by the gate-insulator voltage field, the halving of the gate-oxide thickness should be expected to have a major effect on the gate voltage required. Summary for Bi-directional MOSFET voltage converter. The chief physical structural difference between Logic Level and other MOSFETs, and the electrical reason for its difference in performance, is its gate insulation thickness, which has been reduced from 100nm industry standard to 50nm (500 angstroms), yet which retains the dynamic strength to handle the high voltage applied to power transistors. With the MOSFET switched on then both the LV and HV sides are at 0V giving a logic-low at each side. In such a case, consider changing the drive circuit. When the general-purpose logic IC does not have enough output current capability, the MOSFET cannot be driven.
#MOSFET LOGIC LEVEL DRIVER#
These devices do not require an interface circuit between it and the CMOS logic driver therefore, the extra cost of the interface circuit power supply is eliminated. What is the meaning of Logic-Level Gate Drive for the MOSFET It means the MOSFET can be driven by the output voltage (4 to 5 V) of general-purpose logic IC.
#MOSFET LOGIC LEVEL SERIES#
The NTE series Logic Level MOSFETs are compatible with the 5-volt power-supply requirement of logic circuitry.

The devices have total ionizing dose (TID) capability of up to 300 Krad(Si), single event effect (SEE) immunity to 82 MeV, and are available in screened and commercial off-the-shelf (COTS) versions. The extended family of MOSFETs includes N and P channel in single and multi-chip configurations offered in a range of through-hole and surface mount packages including SMD-0.5, SMD-2, LCC-28, 14 lead flat pack, TO-205AF, Low-Ohmic TO-257AA, and MO-036AB. Moreover, low on-state resistance (RDS(on)), fast switching and small size, make the MOSFETs ideal alternatives to traditional bipolar devices. This helps reduce part count, simplify drive circuitry and enhance reliability.
El Segundo, Calif.International Rectifier, IR, expanded its portfolio of RAD-Hard logic level gate drive MOSFETs with the introduction of 60 V, 100 V and 250 V MOSFETs for switch mode power supplies (SMPS), satellite power distribution systems and resonant power converters in high-reliability applications.Ĭompared to bipolar transistors, the RAD-Hard MOSFETs can be driven directly from CMOS/TTL logic circuitry, eliminating the need for intermediate components.
