BQ771808DPJR General Description
The BQ7718xy family of products provides an overvoltage monitor and protector for Li-Ion battery pack systems. Each cell is monitored independently for an overvoltage condition. For quicker production-line testing, the BQ7718xy device provides a Customer Test Mode (CTM) with greatly reduced delay time.
In the BQ7718xy device, an internal delay timer is initiated upon detection of an overvoltage condition on any cell. Upon expiration of the delay timer, the output is triggered into its active state (either high or low depending on the configuration).
Features
- 2-, 3-, 4-, and 5-series cell overvoltage protection
- Internal delay timer
- Fixed OVP threshold
- High-accuracy overvoltage protection: ± 10 mV
- Low power consumption ICC ≈ 1 µA (VCELL(ALL) < VPROTECT)
- Low leakage current per cell input < 100 nA
- Functional Safety-Capable
- Documentation available to aid functional safety system design
- Package footprint options:
- Small 8-pin QFN (3.00 mm × 4.00 mm)
- Leaded 8-pin MSOP (3.00 mm × 5.00 mm, including leads)
