Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

The TPL7407L complements TI's broad portfolio of peripheral drivers, covering a wide voltage and current range, giving designers the ability to choose a device to suit their needs without extensive ...

This circuit is a relay driver that is based on a PIC16F84A microcontroller. The board includes four relays so this lets us to control four distinct electrical devices. The controlled device may be a ...

Fig. 1: Add this relay to prevent shorted transistors in the MW-1. Usually after a transmitter is discontinued, any hope of upgrades or improvements fades. Some enterprising engineers can’t help but ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (TDSC) today announced the launch of “SSM3K357R,” a new MOSFET that adopts an active-clamp structure with a built-in diode ...

The addition of a components and an unused NC contact to a dc supply provides a power-reducing feature to a relay driver circuit. Electromagnetic relays need much less power for holding than they do ...
