Raspberry Pi Launches the New Compute Module 3
Just over 2 years ago the Raspberry Pi foundation launched the original Compute Module (CM1), which was based around the same BCM2835 processor of the original Raspberry Pi. The Raspberry Pi Foundation launched this board aimed at the industrial market, where companies were using the Raspberry Pi for commercial purposes...
Diodes Incorporated Introduces World's First Power Switch to Fully Support USB Type-C Power Delivery and Hot-Swap Operation
05.06.2017 · News
Diodes Incorporated introduced the DPS1133. This single-channel power switch is the world’s first high-voltage power switch designed to meet all the demanding protection and fast-role swap requirements of USB Type-C™ ports...
Using op amps to reduce near-field EMI on PCBs. Part 2
As shown in previous sections, active filtering and CMRR can reliably reduce circuit noise in the device’s band-limited range, including DM and CM EMI up into the MHz range. However, exposure to RFI noise above the intended operating frequency range may cause non-linear behavior in the device...
STMicroelectronics Introduces Automotive Power MOSFETs in Tiny 5x6mm Dual-Side Cooling Package
01.06.2017 · News
STMicroelectronics has introduced new MOSFET devices in the advanced PowerFLAT 5×6 dual-side cooling package, enabling increased power density in automotive Electronic Control Units...
Using op amps to reduce near-field EMI on PCBs. Part 1
01.06.2017 · Articles
Automotive, industrial, medical, and many other applications use sensitive analog circuits that must perform their function while remaining immune to noise disturbances in their local environment. Many of these disturbances occur on nearby “noisy” circuits located on the same printed circuit board, while other interference can be picked up by cable interfaces that couple noise onto the PCB and its circuits...
TI introduces the industry's smallest gate driver and power MOSFET solution for motor control
01.06.2017 · News
Texas Instruments introduced two new device families that help reduce size and weight in motor drive applications. When used together, DRV832x brushless DC (BLDC) gate drivers and CSD88584/99 NexFET™ Power Blocks require as little as 511 mm2, half the board space of competing solutions...
Resistor compensates for instrumentation-amp gain drift
31.05.2017 · Circuits
Some instrumentation amplifiers use external resistors to set their gain. Unfortunately, the lack of temperature-coefficient matching between the external and the internal resistors results in a high gain drift. If, however, another on-chip resistor is available, you can use it to compensate for gain drift as a result of temperature...
