description

The LTC®2942 measures battery state of charge, battery voltage, and chip temperature in handheld PC and portable product applications. Its operating range is ideal for single-cell lithium-ion batteries. An accurate coulomb meter integrates the current flowing through a sense resistor located between the positive end of the battery and the load or charger. Battery voltage and on-chip temperature are measured using an internal 14-bit No Latency ΔΣTM ADC. The three measured physical parameter values (charge, voltage, and temperature) are stored in internal registers that can be accessed via the SMBus/I2C interface on the board.

LTC2942 Features programmable high and low thresholds for all three measured physical quantities. If a programming threshold is exceeded, the device will use the SMBus alarm protocol or send an alarm signal by setting a mark in the internal status register.

LTC2942 Only a single low-resistance sense resistor is required to set the measurement current range.
