TS1108 - Bidirectional Current Sense Amplifier

TS1108 Data Sheet 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 currentsense 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.
