The BQ294701DSGR from Texas Instruments is an overvoltage monitor and protector for Li-Ion battery pack systems. It provides accurate cell-by-cell voltage monitoring, ensuring battery safety and longevity. The device features factory-programmed overvoltage thresholds ranging from 3.85V to 4.6V with high accuracy of ±10mV.
Designed for 2-, 3-, and 4-series cell configurations, the BQ294701DSGR includes an external capacitor-programmed delay timer. This feature initiates a delay upon detecting an overvoltage condition before triggering the output. It also supports active high or open drain active low output options. The IC boasts low power consumption, drawing approximately 1µA when all cells are below the protection voltage, and low leakage current per cell input of less than 100nA.
This battery protection IC is housed in a small 8-pin WSON package with dimensions of 2.00mm x 2.00mm, suitable for space-constrained applications. The mounting type is surface mount, and it operates within a temperature range of -40°C to 85°C. The standard package quantity is 3000 units on tape and reel.
