I have the following circuitry: Battery Supply => Current Monitoring Circuitry => DC Motors
Battery Supply: 4AA NiMH batteries - 4*1.2V (1.5mAh * 4)
Current Monitoring Circuitry: Max 4378 chip (contains 4 current-sense op amps)
I have used the Max 4378 chip for monitoring the energy levels of low-power applications. But now I want to use it to measure the energy consumption of driving two motors. Unfortunately, the chip has a max current supply, Icc, of 2.2mA.
Is there a chip I can use for energy monitoring that doesn't get fried by high currents in the order of 1.5 - 2 Amps? or perhaps an alternate method?
