Electronic Specifier takes a look at the top 5 power products to have been released in December 2023.

30V MOSFET fires up production for automotive makers

Magnachip Semiconductor has begun full-scale mass production of its new 30V MXT LV Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) used in Electronic Control Units (ECUs) of Electric Power Steering (EPS) systems.

This MOSFET product is being used by a global automaker.

The 30V MXT LV MOSFET provides a stable power supply to EPS, assisting a vehicle’s directional control through an electric motor.

Buck-boost converter developed for wearables and IoT

The MAX77837 from Analog Devices (ADI) is an extremely small nanoPower buck-boost converter optimised for single-cell battery chemistries used in wearable and Internet of Things (IoT) applications.

It is in stock at authorised distributor DigiKey.

The converter operates on an input supply between 1.8 to 5.5V. Output voltages between 1.8 to 5.2V are set through resistors connected to two hardware control pins. The IC can operate in continuous conduction mode (CCM), skip mode, and a low-power mode to ensure high efficiency over a wide load current range.

Compact DC-DC converters help reduce PCB size, cut costs

TDK has released the FS series of µPOL DC-DC converters for demanding applications such as big data, machine learning, artificial intelligence (AI), 5G cells, IoT, computing enterprise and many others besides.

These DC-DC converters are compact and highly integrated point-of-load converters for powering CPUs, MCUs, ASICs, FPGAs, DSP, and other advanced digital logic devices, providing the high performance, fast load transient response, and high accuracy voltage regulation needed by these devices.

Micro-POL converters are high current density power modules that feature a chip-embedded power IC in a thermally enhanced semiconductor-embedded-in-substrate package.

High-voltage, automotive-compliant, hall-effect latches from Diodes

Diodes has added the AH371xQ series of high-voltage Hall-effect latches to its product portfolio.

These automotive-compliant devices feature a proprietary Hall plate design that boosts performance. They are used for brushless DC (BLDC) motor control, valve operation, linear and incremental rotary encoders, and position-sensing functions. Based on this, the AH371xQ series can support numerous in-vehicle comfort and engine management applications—including window power-lift and sunroof movement, tailgate opening/closing mechanisms, seat adjustment motors, cooling fans, water/oil pumps, and speed measurement.

These Hall-effect latches have an operating voltage range from 3V to 27V, with 40V load dump protection. This gives them the versatility to integrate into a wide variety of automotive systems. The devices have a chopper-stabilised design that mitigates the effects of thermal variation and provides enhanced stray field immunity. Their power-on time is typically 13µs.

High precision voltage tracker for automotive

Nisshinbo Micro Devices has launched the NJW4250 intended for automotive applications, ECU, Body Equipment, power supply for off-board sensors.

Automotive vehicles are equipped with an increasing number of electronic systems for various purposes; all these circuits are powered from a primary supply followed by several secondary power management ICs. In particular, off-board sensors are wired throughout the vehicle and, therefore, require additional safety measures to ensure that a shared power supply of the sensor, ECU, or other essential circuits remains operational in the event of a failure in the sensor devices.

Therefore, it is a popular measure to use so-called Voltage Trackers as a buffer power supply, where a reference supply voltage is replicated with high tracking accuracy and the safety level of the electronic system is generally increased.
