By Peter Friedrichs, Infineon Technologies SiC and GaN devices operate at higher stress levels than silicon devices. The semiconductor and automotive industries have strict qualification tests for that. Silicon carbide (SiC) and gallium nitride (GaN) wide bandgap (WBG) technologies are well known for their performance advantages over silicon (Si) in many high-power areas, including their […]

Power BJTs available in DFN2020D-3 packaging with 50 V and 80 V ratings
Nexperia announced the latest extension to its popular portfolio of power bipolar junction transistors (BJTs) with the release of ten standards and ten automotive-qualified products in DFN2020D-3 packaging. These new devices, available in 50 V and 80 V ratings and supporting current ranges from 1 A to 3 A in NPN and PNP polarity, further […]
Selection and implementation of BLDC control strategy
By Shoa Zhang, Qorvo Understanding the differences between trapezoidal, sinusoidal, and field-oriented control can help engineers understand the value of Field Oriented Control (FOC) and the choices available to optimize their designs. BLDC motors can be smaller, lighter, and quieter than traditional brushed DC motors while enhancing the reliability and energy efficiency of consumer, industrial, […]
12-channel LED driver sinks 60 mA
Diodes Incorporated introduces a new 12-channel, constant-current LED driver, the AL58221. It features 12 open-drain outputs that are rated to 24V and sink up to 60mA of high-accuracy current with a fast transient response. The channel-to-channel LED current accuracy is typically ±1% and the regulated output current tolerance is ±0.1%. Operating over a 3V to 5.5V […]
Add gas discharge tubes to your circuit-protection device roster
GDTs are circuit-board-compatible overvoltage-protection devices and are far removed from the “spark gap” of monster movies. Circuit protection is like insurance: you really don’t need it until you unexpectedly do, and then you’re very glad you have it. This protection falls into two broad categories: protection against overcurrent (the common thermal fuse is the first […]
