BQ29449DRBR Ratings and Reviews

E**u

Everything fine

2019-04-12

A***o

It took a long time, but rather it's mail fault.

K***v

One percent warmed himself when trying to put a hairdryer, the other put a soldering iron-the radio tape does not load further than the saver.

BQ29449DRBR Description

***as Instruments: Secondary Over-Voltage Protection for 2-4 cell in series Li-Ion/Poly (4.30V) 8-SON -40 to 85

***ical: Overvoltage Protection Device Li-Ion 4.3V 8-Pin VSON EP T/R

***i-Key: IC V-PROT 2-4CELL LI-ION 8SON

***XS: The bq2944x is a secondary overvoltage protection IC for 2-series, 3-series, or 4-series cell Li-Ion battery packs that incorporates a high-accuracy precision overvoltage detection circuit.

***ASI: FUNCTION

***AS INST: The voltage of each cell in a battery pack is compared to an internal reference voltage. If any cells reach an overvoltage condition, the bq2944x device starts a timer that provides a delay proportional to the capacitance on the CD pin. Upon expiration of the internal timer, the OUT pin changes from a low state to a high state. An optional latch configuration is available that holds the OUT pin in a high state indefinitely after an overvoltage condition has satisfied the specified delay timer period. The latch is released when the CD pin is shorted to GND.
