This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the user ...

The 0- to 20-mA current loop isa reliable means of data communicationin industrial applications.These circuits use a precision shunt inthe receiver to convert the current signalinto a voltage signal.

IC timers are programmable semiconductor circuits that generate or set timing for electronic circuits. These chips function as single or multi-function units. An IC timer works by charging and ...

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers ...

The future’s cheap and yellow.

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...
