TS1108 Coulomb Counter: Bidirectional Current Sense Amplifier with Integrator + Comparator

The TS1108 coulomb counter accurately measures battery depletion while also indicating the battery charging polarity. The battery discharge current is monitored by a current-sense amplifier through an external sense resistor. Utilizing an Integrator and a Comparator plus a Monoshot, the TS1108 voltage-to-frequency converter provides a series of 90 μs output pulses at COUT which represents an accumulation of coulombs flowing out of the battery. The charge count frequency is adjustable by the integration resistor and capacitor.
