Two omnipolar magnetic switches, the LF21173TMR and LF21177TMR from Littelfuse, combine tunneling magnetoresistance (TMR) and CMOS technologies in a compact LGA4 package. Compared with conventional ...
Computer engineering, but in particular mobile computer engineering, is all about playing a zero-sum game with yourself. Power and efficiency are constantly undercutting one another, creating ...
Littelfuse has created a three pin magnetic switch that draws only 200nA and operates at up to 50Hz. Called LF21112TMR, the detector uses a combination of TMR (tunnelling magneto-resistance) sensing ...
