High-Voltage Amplifier Extends Coulomb-Counter Range to ±270 V
High-Voltage Amplifier Extends Coulomb-Counter Range to ±270 V
14.04.2017 · Circuits
Low-range current measurement is a challenge when the associated voltage is relatively high, but a configuration of standard ICs meets the requirements. A coulomb counter can measure charge that flows into or out of a battery, and small, dedicated ICs can directly interface with low-to-medium battery voltages of up to about 20 V...
