It tracks charge and discharge in a 1-cell Li-Ion stack, reporting accumulated charge, voltage, and temperature through the bus. The device is housed in a 6-WFDFN exposed pad package (6-DFN 2x3 mm), and operates across the industrial temperature range of -40°C to 85°C. This makes it a direct fit for portable instrumentation, field sensors, and battery-backed systems where the host MCU reads fuel-gauge data over a two-wire bus. ## I²C bus – what it means for system integration The I²C interface uses only two wires (SCL, SDA) and supports standard and fast-mode speeds. Because the LTC2942IDCB#TRMPBF is a bus slave, multiple battery monitors or other I²C peripherals can share the same bus without extra GPIOs. The exposed pad (6-WFDFN) requires a thermal via pattern under the pad to the ground plane – the datasheet layout note is worth following for consistent temperature readings. ## One cell only – no multi-cell stacking The LTC2942IDCB#TRMPBF is specified for a single Lithium Ion cell. If the BOM calls for monitoring a 2-cell or higher series stack, this part cannot be used directly – the internal sense and protection circuits are scaled for one cell. For multi-cell designs, look at the LTC2943 or LTC2944 family (not stocked here, but a common industry path). ## Active lifecycle – no near-term obsolescence The LTC2942IDCB#TRMPBF carries an active product status. ROHS3 compliant. For new designs or production replenishment, this part can be qualified into the BOM without worrying about a phase-out in the next few years.","metaTitle":"LTC2942IDCB#TRMPBF Battery Monitor, I²C, 6-DFN, Active","metaDescription":"ADI LTC2942IDCB#TRMPBF single-cell Li-Ion battery monitor with I²C interface.
