Typical Applications
IAUC90N10S5N062ATMA1 is suitable for 6 applications: 48V MHEV DC-DC Converter, Electric Power Steering (EPS) Motor Drive, Automotive High-Side Load Switch, Battery Disconnect / OR-ing Switch, Industrial 48V Synchronous Rectifier, USB Power Delivery and E-Fuse.
48V MHEV DC-DC Converter
The IAUC90N10S5N062ATMA1 is purpose-built for 48 V mild-hybrid electric vehicle (MHEV) DC-DC converters that step down from 48 V to 12 V. Its 100 V VDS rating provides margin above the 48 V nominal bus and handles 100 V load-dump transients defined by ISO 21780, while the 6.2 mOhm RDS(on) at VGS=10 V minimizes conduction loss in high-current synchronous rectifier stages (>1000 W). The 90 A continuous drain current (Tc=25 C) supports 1-2 kW power levels per device, allowing a single FET per phase instead of paralleling. The AEC-Q101 qualification, MSL1 rating, and 175 C max junction temperature make it qualified for under-hood and transmission-mounted power electronics where ambient temperatures routinely exceed 125 C.
Recommended
Electric Power Steering (EPS) Motor Drive
The IAUC90N10S5N062ATMA1 is used as the low-side switch in three-phase brushless DC motor drives for column-assist EPS systems and rack-assist EPS systems. The 90 A continuous current rating supports the high inrush torque demands during parking maneuvers, while the 6.2 mOhm RDS(on) keeps I2R conduction loss below 10 W at typical 30 A phase currents. The PG-TDSON-8-34 package's exposed die pad enables direct PCB heatsinking with no external heatsink required, which is critical for the space-constrained steering column housing. AEC-Q101 qualification and 100% avalanche testing meet ISO 26262 ASIL requirements for safety-critical steering subsystems.
Recommended
Automotive High-Side Load Switch
In automotive ECU load-switch applications (lighting, seat heaters, window lifters), the IAUC90N10S5N062ATMA1 serves as a high-side N-channel switch driven by a charge-pump gate driver. Its 100 V VDS rating handles the worst-case 24 V jump-start and 100 V load-dump transients required for 12 V automotive electrical systems per ISO 7637-2. The 6.2 mOhm RDS(on) keeps voltage drop below 50 mV at 8 A typical load currents, and the 90 A peak rating covers inrush on capacitive loads such as LED matrix headlights. The part's 100% avalanche-tested ruggedness protects against the inductive kickback of relays and solenoids.
Recommended
Battery Disconnect / OR-ing Switch
The IAUC90N10S5N062ATMA1 functions as a back-to-back OR-ing switch or battery disconnect in dual-battery automotive architectures (starter battery + auxiliary battery). Two MOSFETs in common-source configuration block reverse current flow with a typical forward drop of just 5 mV at 30 A (2 x 6.2 mOhm). The 100 V rating covers 48 V mild-hybrid battery packs. The AEC-Q101 and 175 C junction temperature ratings ensure reliable operation in engine-bay mounted battery management units. The PG-TDSON-8-34's source-down footprint simplifies PCB layout for the back-to-back configuration with a shared heatsink tab.
Recommended
Industrial 48V Synchronous Rectifier
In industrial telecom and solar 48 V bus converters, the IAUC90N10S5N062ATMA1 is used as the synchronous rectifier MOSFET on the secondary side of isolated DC-DC converters. Its 6.2 mOhm RDS(on) at full 10 V VGS outperforms most planar MOSFETs in the same class, reducing rectifier conduction loss by approximately 30% compared to the previous OptiMOS 3 generation. The 90 A rating supports 2-3 kW converter modules with a single FET per phase. The PG-TDSON-8-34 package's low thermal resistance (~1 C/W junction-to-case with proper PCB thermal design) enables high power density designs without forced-air cooling.
Recommended
USB Power Delivery and E-Fuse
In USB Power Delivery (USB-PD) 100 W and higher applications and automotive electronic fuse (e-fuse) circuits, the IAUC90N10S5N062ATMA1 serves as the main hot-swap switch protecting downstream loads. Its 100 V VDS rating covers 28 V USB-PD Extended Power Range (EPR) rails with margin, while the 6.2 mOhm RDS(on) keeps voltage drop under 100 mV at 5 A continuous load. The 90 A peak rating handles the 100 W EPR inrush (5 A at 20 V). The part's 100% avalanche-tested ruggedness absorbs the inductive kickback of downstream cable harnesses during hot-unplug events, replacing traditional mechanical fuses with a resettable solid-state solution.

Design Notes
Estimated: at continuous 90 A load with VGS=10 V, conduction loss alone is I2 x RDS(on) = 90^2 x 0.0062 = 50.2 W (using max RDS(on) of 6.2 mOhm). The PG-TDSON-8-34 package has a junction-to-case thermal resistance of approximately 0.5 C/W with the exposed pad soldered to a 2 oz copper pour of at least 100 mm^2. To keep Tj below 175 C at 25 C ambient, total power dissipation must stay below approximately 0.85 W per degree of rise, requiring a heatsink or substantial copper area for sustained high-current operation.
The PG-TDSON-8-34 source-down footprint requires the PCB copper pour under the exposed pad to act as the heatsink. Use a thermal via array (typically 9-16 vias of 0.3 mm diameter on 1.0-1.2 mm pitch) connecting the top copper pour to inner copper planes. Place input and output capacitors (gate driver bypass, decoupling) within 5 mm of the gate pin to minimize parasitic inductance that causes gate ringing and possible Miller-induced turn-on.
Critical: never operate the IAUC90N10S5N062ATMA1 at VGS below the typical VGS(th) of 3.8 V at high currents - the device will operate in the linear region with massive power dissipation and likely thermal failure. Always verify the gate-drive voltage reaches the full 10 V specified in the datasheet. Also, the 90 A continuous rating assumes Tc=25 C; at typical PCB-mounted case temperatures of 80-100 C, derate to approximately 50-65 A continuous to stay within SOA.
For high-frequency switching (>100 kHz in 48 V MHEV converters), minimize the source-to-gate loop inductance by routing the gate-driver return directly to the Kelvin source pin (pin 1-3) rather than to the power source. Without Kelvin connection, the source inductance causes a negative voltage spike at the gate during turn-off, potentially creating a self-turn-off / parasitic oscillation loop. Use a 10-100 ohm gate resistor to dampen the gate loop.
