The BQ294604DRVT from Texas Instruments is a secondary-level overvoltage monitor and protector specifically designed for 1-cell Li-Ion battery pack systems. This device monitors the cell voltage and triggers an internal counter when the Overvoltage Protection (OVP) threshold is exceeded. After a fixed delay of 4 seconds, the output transitions to a high level, indicating an overvoltage condition.
The BQ294604DRVT features a fixed OVP threshold of 4.35V, with high accuracy of ±10mV. It operates with low power consumption, drawing approximately 1µA when cell voltages are below the protection threshold, and exhibits low leakage current per cell input of less than 100nA. The device is housed in a compact 6-pin WSON package, suitable for surface mounting.
This battery protector is ideal for applications requiring reliable overvoltage detection and protection for single-cell Lithium-Ion batteries, ensuring the safety and longevity of the battery pack. Its small footprint and low power characteristics make it suitable for various portable and space-constrained designs.
