High-Voltage Amplifier Extends Coulomb Counter Range to +/-270V
Jan 22nd 2016
Introduction
A coulomb counter can measure charge that flows into or out of a battery. Small, dedicated devices such as LTC2941 or LTC2943 can directly interface with low to medium battery voltages, up to about 20V. You can extend the input operating range of the measurement circuit by using a high-voltage amplifier as a level ...
