Analogue / Linear / Mixed Signal ICs

Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer look. No permanent magnet, external or internal, is needed, and external magnetic fields are rejected. MLX92442 only requires a nearby electrically conductive object for triggering. It comes in either ...

Alpha and Omega Semiconductor has released a 7A 23V USB Type-C protection and reverse-blocking switch IC. Dubbed AOZ1377DI, is can be used in both Sink and Source applications and it “offers features that significantly reduce voltage drop and power loss compared to back-to-back p-channel devices”, promises the company. Instead it uses a pair of internal drain-to-drain n-channel mosfets, whose gates ...

EPC has used GaN transistors to create a high-power Class-D two-channel audio power amplifier design. Instantiated in evaluation kit EPC9192, it is capable of pushing 700W/channel into 4Ω (or 2Ω) or 350W/channel into 8Ω. Bridging the two channels results in 1.4kW drive into 4 to 8Ω. Key components, per channel, are a pair of 200V EPC2307 GaN transistors on a ...

The diverse challenges facing 5 distinct product segments. When it comes to electronics, most designs will involve multiple semiconductor devices. With this point in mind, Rochester Electronics’ goal is not to offer a single solution for an obsolete device, but instead provide a range of solutions covering the many mature devices likely found in designs. For example, finding a solution ...

Innoscience Technology has created a gate driver specifically for GaN power transistors. The single-channel INS1001DE is intended to supply fast powerful voltage-regulated waveforms to the gates, which are extremely sensitive to over-voltage stress. Its output pulse amplitude is set by a low-drop-out regulator using two resistors, to, for example 6V which is commonly specified for enhancement-mode GaN hemts (diagram below ...

TDK has announced automotive smart motor drivers that can handle 4 x 1A peak current and include an Arm Cortex-M3 processor core. HVC 5222D with 32kbyte of flash and HVC 5422D with 64kbyte can drive brushless dc, brushed dc (2A) and stepper motors. They also have 4kbyte ram, 2kbyte of emulated eeprom and 1kbyte of non-volatile registers, and are “SEooC ...

Abaco Systems latest analogue front-end mezzanine card for FPGAs has been tailored for software defined radio, as well as electronic warfare, radar, test and measurement. FMC300, as it will be known, has 7GHz of usable analogue bandwidth, claims the company, with multiple channels offering up to 12bit 6Gsample/s ADC and up to 16bit 12Gsample/s DAC through a JESD204B/C interface. Data ...

Analog semiconductor manufacturer ABLIC Inc. embarked on a new start under a new company name in 2018, against the backdrop of a rich history spanning over 50 years. In June 2023, five years later, Seiji Tanaka took office as the new president. While focusing on planning and development capabilities as well as high-value-added products, Tanaka is also strengthening initiatives in ...

Nexperia has unveiled analogue switches that can work with control logic from 1.8 to 5V, regardless of supplies between 1.5 and 5.5V. There are two versions: NMUX1308, an 8:1 analogue multiplexer/demultiplexer which is compatible with, but more capable than, existing 4851 and 4051 analogue switches, and the NMUX1309 dual 4:1 analogue mux/demux which can replace 4852 and 4052 devices. All ...

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers instead of CAN, or a CAN interface without transceivers, or no CAN or LIN, and a base model has a 70MHz processor. Some have SENT interfaces for ...
