Battery protection IC in a 9-bump WLP
The Analog Devices MAX14606EWL+T is a dedicated battery protection IC designed to monitor and safeguard single-cell lithium-ion or lithium-polymer packs. Its primary function is to detect over-voltage and over-temperature fault conditions and disconnect the cell from the load or charger, preventing damage during charging or deep discharge events. The device is specified over the industrial temperature range of -40°C to 85°C, making it suitable for portable equipment exposed to outdoor or unconditioned environments — power tools, medical monitors, or handheld instruments that see seasonal temperature swings.
Protection features and temperature grade
The MAX14606EWL+T integrates over-voltage and over-temperature fault protection. Over-voltage protection prevents the cell voltage from exceeding a safe threshold during charging, while over-temperature protection disconnects the cell if the die temperature rises above the rated limit — a safeguard against runaway charging or external heating. With an operating temperature range from -40°C to 85°C, this IC is rated for industrial-grade applications. That covers most portable and handheld gear that lives indoors or in a vehicle cabin, but not under-hood automotive or extended high-temperature environments above 85°C.
