This project provides a platform to evaluate the OPA462 high-voltage, high-current operational amplifier. Multiple component footprints allow the most common circuit configurations. The board accommodates high-voltage and high-current operational amplifier OPA462 from Texas...

The project presented here is a three-phase sinewave PWM driver for high-voltage brushless motors. The board is built using TB67B000AHG chip, which is a high-voltage IC capable of handling 600V. The TB67B000AHG has a 2-in-1 (MCP) structure of controller (sine-wave PWM / wide-angle...

This Bar-Graph Display provides a high visibility 15-Segment Bar-Graph display for current measurements. A buzzer provides audible sound when an over-current condition event occurs. The 15 segments are made with Red, Blue, Green, and yellow color LEDS. All LEDs are SMD size 1206. This...

This is a single-channel, fully-protected, high-side power switch with programmable current-limit. Full diagnostics and high-accuracy current-sense features enable intelligent control of the load. A programmable current-limit function greatly improves the reliability of the whole...

The project presented here is a USB port-powered, USB 2.0 isolator that isolates the USB host and USB device. It is a galvanically-isolated USB2.0 repeater, that supports low speed 1.5Mbps, and full speed 12Mbps communication. The project automatically connects and detects the bus...

This is a versatile synchronous buck DC/DC converter built using the LM5008 chip. The operating input voltage range is 12V to 95V DC, providing 5V/120-350mA output. The regulator can provide a load current of up to 350mA, but it's advisable to draw only 120mA due to the small thermal...

This is a 3-Phase Inverter Driver project designed for Small Power AC Motors. The project is built using FSB50550AT IPM chip. This compact and reliable inverter project is ideal for small power motors such as fans and pumps. An H-bridge configuration can also be created for low...

This is a 3-Phase Inverter Driver project designed for Low Power AC Motor. The FSB50450AS chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. An H-bridge configuration can also be created for low-current high-voltage...
