It uses the 1-Wire interface for communication, which means a single data line plus ground carries both power and bidirectional data — handy when you're routing a flex circuit inside a battery assembly and want to minimize wire count. It's built for Smart Batteries chemistry packs and comes in an 8-SOIC surface-mount package, so it fits on a small PCB inside the battery housing or on a companion board. The operating temperature range of -40°C to 85°C covers industrial and outdoor equipment — think telecom backup batteries, portable medical devices, or electric vehicle auxiliary packs that see cold starts and hot engine bays. ## Lifecycle and sourcing reality That means you can qualify it into a new BOM without worrying about a last-time-buy window closing mid-production. For procurement: this part is sourced through independent distribution and quoted to order against an RFQ. ## Package and mounting The 1-Wire bus is a single-wire protocol that carries both data and power over one line plus ground. The DS2438Z+ is a slave device, so it responds to commands from the host. If you're replacing a failed part on a board, the scorch mark will usually be on the supply pin if the battery pack shorted; check the 1-Wire line for pulled-up voltage before blaming the chip.","metaTitle":"DS2438Z+ Battery Monitor, 1-Wire, 8-SOIC, Active","metaDescription":"DS2438Z+ Smart Battery Monitor IC from Analog Devices. 1-Wire interface, 8-SOIC package, -40°C to 85°C range.
