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 ...
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 ...
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 ...
Designed for operation across the voltage range 1.8 V–5.5 V, the LF21173TMR and LF21177TMR support multiple magnetic thresholds, enabling flexible integration into space-constrained applications such ...
