 A range of AEC-Q100-compliant ICs optimised for implementation into next-gen automobile designs have been introduced by ON Semiconductor. The NBA3N200/1/6S M−LVDS line driver/receiver family of devices operate from a 3.3V power supply. 

The NBA3N200S and NBA3N201S both support signalling rates of up to 200Mb/s and have a common-mode voltage range of -1 to +3.4V. These devices have Type-1 receivers that detect the bus state with as little as 50mV of differential input voltage over the common-mode voltage range. A differential input voltage hysteresis of 25mV on the receiver prevents oscillations at the output due to slow changing input signals or loss of input. The NBA3N206S also supports 200Mb/s signalling rates with a Type-2 receiver that has a 0.1V threshold. The offset voltage threshold function of the Type-2 receiver can detect open-circuit, idle bus and various other fault conditions that could harm the system. These devices are targeted for use in automotive applications such as headlamp pixel lighting, specifically for data transmission between the LED front light control unit and the headlight.

The NCV8154 140mV rated dual output linear voltage regulator has an input voltage range covering 1.9 to 5.25V and two independent input voltage pins. Highly optimised for powering the RF blocks within automotive infotainment systems, this device is capable of providing a very stable and highly accurate voltage, with ultra-low noise plus elevated PSRR. The NCV8170 LDO regulator is designed specifically for portable battery-powered applications, such as vehicle keyless entry systems, with a typical current consumption of just 500nA. Furthermore, a dynamic transient boost feature augments this device’s transient response characteristics. The NCV8715 is a high stability 50mA LDO with an input voltage range that reaches up to 24V and a ground current consumption of 4.7µA over the full output load range. This device is very well suited to use with automotive grade MCU units. The NCV8154, NCV8715 and NCV8170 devices each feature thermal shutdown and current limit protection mechanisms that ensure reliable operation.

Also introduced, are single N-channel MOSFET devices capable of delivering incredibly low on-state resistance RDS(on) figures, thereby minimising conduction losses and improving overall operational efficiency levels. The NVMFS5C404NL, NVMFS5C410NL, NVMFS5C423NL and NVMFS5C442NL 40V rated MOSFETs have typical RDS(on) values at 10V of 0.56, 0.71, 1.6 and 2.2mΩ respectively. These are supplemented by the 60V NVMFS5C604NL, NVMFS5C612NL, NVMFS5C646NL and NVMFS5C670NL devices, which have typical RDS(on) values at 10V of 0.93, 1.2, 3.8 and 5.1mΩ respectively. These devices expand the extensive ON Semiconductor portfolio of MOSFETs for use in power switching, load switching, motor control, and other automotive applications.
