Hi All,
I've previously used complimentary pairs (eg DMC2990UDJ) to switch ICs on and off.
I've attached a schematic which switches a potential divider for battery voltage monitor as an example. Where R7 and R8 are I'd add a sensor instead.
I'm now designing a battery powered sensor board which needs many switches. Are there any ICs suitable for this which only take a couple of nano amps when powered down which doesn't need the external resistors (R4, R5 & R6?
