Tiny 32.768kHz MEMS resonator reducing size of devices
It has been announced that Murata has developed what they believe to be the world’s smallest 32.768kHz MEMS resonator (the WMRAG series), which is expected to make a significant contribution to reducing the size and power consumption of IoT devices and wearable devices.
Automotive-grade BCD process technology with up to 200V operation
Designer and manufacturer of analog and mixed-signal semiconductor products, MagnaChip Semiconductor has offered Foundry customers a 0.18 micron BCD (Bipolar-CMOS-DMOS) 200V high-voltage process. This new BCD process uses SOI (Silicon On Insulator) substrates with solid high-voltage isolation and extends MagnaChip’s existing BCD processes from 100 to 200V.
GaN power stage meets electric motor requirements
Boasting ultra-low input and output capacitance, the LMG3410R070 600V 70mΩ gallium nitride (GaN) power stage from Texas Instruments supports new requirements for high-power-density electric motor applications, including industrial and consumer power supplies. It is in stock at Mouser Electronics.
Sixteen cell battery monitor with passive cell balancing
The bq76PL455A-Q1 device from Texas Instruments is an integrated 16-cell battery monitoring and protection device, designed for high-reliability automotive applications. The integrated high-speed, differential, capacitor-isolated communications interface allows up to sixteen bq76PL455A-Q1 devices to communicate with a host via a single high-speed Universal Asynchronous Receiver/Transmitter (UART) interface.
Power modules provide solution for vehicle on-board charging
A driver of energy efficient innovations, ON Semiconductor has launched new Automotive Intelligent Power Modules (IPMs) that offer good power density and improve overall performance in on-board charging (OBC) and other high-voltage DC/DC conversion applications for electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs).
AC-DC efficiency measurements need to include power factor
Power converter designers compete to minimise losses, chasing the last decimal points of efficiency, η, the ratio of output to input power. But when it comes to calculating efficiency in AC-DC power supplies mistakes are often made as a result of omitting or improperly measuring power factor, which is why it is important for designers to understand power factor basics and how to incorporate it.
Automotive design steps up EMI standards
Automotive and industrial design demands compact power supplies that meet low EMI standards, says Joey Yurgelon, Jesus Rosales, and Mark Marosek, Analog Devices
