TI has released a couple of isolated switch chips, one inductive and the other capacitive, to replace electromagnetic and opto-electronic relays in vehicles with 800V batteries. TPSI3050-Q1 is the inductively-isolated (5kVrms reinforced) IC, a switch driver that delivers a 10V gate drive on its secondary side as well as a continuous 50mW dc supply for auxiliary circuitry ...
