The BQ771807DPJR is a battery overvoltage protection IC designed by Texas Instruments. It is typically used in lithium-ion and lithium-polymer battery applications to ensure safety by monitoring cell voltages and providing an overvoltage signal if any cell exceeds its specified threshold.
The BQ771807DPJR comes in a WSON (DPJ) package, which has 8 pins. Here is a brief overview of its main pins and functions:
1. VC1-VC4 (Pins 1-4): These pins are used for monitoring the voltage of each cell in a multi-cell battery pack. VC1 is connected to the bottom cell, and VC4 is connected to the top cell.
2. VSS (Pin 5): This is the ground pin and serves as the reference voltage for the device.
3. CD (Pin 6): This pin is used as the delay time control for the overvoltage detection. It determines the delay before the overvoltage protection is triggered.
4. OUT (Pin 7): This is the output pin that goes high when an overvoltage condition is detected.
5. VC5 (Pin 8): This pin connects to the top of the highest cell in the series, providing power to the device.
These pins collectively enable the BQ771807DPJR to effectively monitor and protect battery cells from overvoltage conditions.
