BQ2969XY規(guī)格書詳情
1 Features
? 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)
2 Applications
? Notebook PC
? Ultrabooks
? Portable medical electronics
? UPS battery backup systems
3 Description
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 selfdisable
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.
