EVM User's guide:
The BQ2969 family is a high-accuracy, low-power overvoltage protector with a 3mA regulated output supply for Li-ion and LiFePO4 (LFP) battery pack applications.
Each cell in a 2-series to 4-series cell stack is individually monitored for an overvoltage condition. An internally fixed-delay timer is initiated upon detection of an overvoltage condition on any cell. Upon expiration of the delay timer, the output pin is triggered into an active state to indicate that an overvoltage condition has occurred.
The regulated output supply delivers up to 3mA output current to drive always-on circuits, such as a real-time clock (RTC) oscillator. The BQ2969 family has a self-disable function to turn off the regulated output if any cell voltage falls below a programmable undervoltage threshold, thereby preventing drain on the battery.
The BQ2969 family provides exceptionally low power operation, drawing only 1.23µA during normal operation (excluding regulator load current), and dropping to 0.25uA when in an undervoltage condition. Even when in the undervoltage state, the device can still detect an overvoltage condition on any other cell (which can occur in an imbalanced pack) and can assert the output pin.
- 2-series, 3-series, and 4-series cell overvoltage protection (OVP)
- Factory programmed OVP threshold (3.6V to 5.2V) with ±12mV accuracy
- Fixed delay timer to trigger FET drive output (0.25s to 6.5s options)
- Output pin options:
- Active high
- Open-drain - active pulldown
- Open-drain - inactive pulldown
- Integrated 3mA regulated output programmable to 3.8V, 3.3V, 3.15V, 3.0V, 2.5V, 1.8V, or 1.5V
- Factory programmed undervoltage (UV) detection threshold (1V to 4.15V) to disable regulator
- OVP remains operational even in undervoltage condition
- Multiple power modes:
- NORMAL mode - no OV or UV: ICC ≅ 1.23µA
- Undervoltage mode - UV detected: ICC ≅ 0.25µA
- Overvoltage mode - OV detected: ICC ≅ 19µA
- Low leakage current per cell input < 100nA
- Small package footprint
- 8-Pin WSON (2mm × 2mm)
