Allegro MicroSystems Europe announces its first ever 1MHz bandwidth Hall-effect current sensor IC with a lightning fast 210 ns response time. The ACS730 provides an economical and precise solution for AC or DC current sensing. Allegro’s ACS730 is targeted at industrial, commercial, and communications systems. Typical applications include motor control, load detection and management, switched-mode power supplies, and over-current fault protection. This device consists of a precise, low-offset, linear Hall-sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimised through the close proximity of the magnetic field to the Hall transducer. A precise, proportional voltage is provided by the Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope when an increasing current flows through the primary copper conduction path (from pins 1 and 2, to pins 3 and 4), which is the path used for current sensing. The internal resistance of this conductive path is typically 1.2 mΩ, providing low power loss. The terminals of the conductive path are electrically isolated from the sensor leads (pins 5 through 8). This allows the ACS730 current sensor IC to be used in high-side current sense applications without the use of high-side differential amplifiers or other costly isolation techniques. The ACS730 is provided in a small, low-profile surface-mount SOIC-8 package. The lead frame is plated with 100% matt tin, which is compatible with standard lead (Pb) free printed-circuit-board assembly processes. Internally, the device is Pb-free, except for flip-chip high-temperature Pb-based solder balls, currently exempt from RoHS. The device is fully calibrated prior to shipment from the factory.

Hello, Bitfoic! The BD140 is a common NPN silicon transistor that is widely used in various electronic circuits such as amplifiers and switching applications. Transistor pin configurations typically follow certain standards, but different manufacturers may use varying packaging methods. For the BD140, it usually has three pins corresponding to the Emitter (E), Base (B), and Collector (C). In A Typical To-92 Package, The Pinout Of The Bd140 Is As Follows: From the bottom view, from left to right: Emitter (E), Base (B), Collector (C). Looking from the top with the marking side facing you, the first pin on the left is the Emitter (E), the middle pin is the Base (B), and the rightmost pin is the Collector (C). However, different manufacturers might have different packaging, so if the pin configuration of the BD140 you encounter seems different from the above description, it's best to consult the specific manufacturer’s datasheet or specifications to confirm the pin functions.

A few weeks ago, I wanna make a CNC machine. So I think about it, what kind of things I will need. It likes I need some 3D print parts, a PCB assembled board and some drive. I have a full 3D print skill and I know how to use a drive to make a CNC machine. But as you know, buy a PCB assembled board is not impossible to buy an only one, I don't have a enough money to buy more than 10 pcs, I am just a student. Lucky, one of my friend Tommy, tell me this company: NextPCB Omg, there are has a big discount for the PCB assembly board, and it was crazy if you are new on this website. Only $7 for 5 pcs. That was fantastic!

CC2650 LaunchPad kit brings easy Bluetooth Smart connectivity to the LaunchPad kit ecosystem with the SimpleLink, ultra-low-power CC26xx family of devices. It is available now from Digi-Key. This kit also supports development for multi-protocol support for the SimpleLink, multi-standard, wireless MCU and the rest of the family of products: the CC2630 wireless MCU for ZigBee/6LoWPAN and the CC2640 wireless MCU for Bluetooth Smart. The wireless MCU contains a 32-bit ARM Cortex-M3 processor that runs at 48 MHz as the main microcontroller and a rich peripheral feature set that includes a unique, ultra-low-power sensor controller. This sensor controller was created for interfacing external sensors and for collecting analog and digital data autonomously while the rest of the system is in sleep mode. The LaunchPad kit supports programming and debugging from Code Composer Studio and IAR Embedded Workbench IDEs.
