Part Number: CSD83325L Other Parts Discussed in Thread: CSD85302L , Hi,
We are evaluating using either CSD83325L or CSD85302L along with TI's BQ29700 for our single-cell lithium-polymer battery protection circuit. Our use-case is for a very low power…
Part Number: BQ2970 Other Parts Discussed in Thread: CSD83325L , CSD85302L Hi,
We are working on an application for a wearable device that utilizes an extremely small capacity lithium polymer cell (30mAh) and completes the battery protection circuitry on…
Other Parts Discussed in Thread: CSD85302L I'm using a BQ29733 battery protection circuit in a standard configuration (with a CSD85302L MOSFET). However when battery power is first applied, the BQ29733 only sometimes turns on the external MOSFETs. Most…
BQ29707 MRK F5 does not set DOUT LOW at 0.1V on V-, but oscilates at 35.6 Hz = NOK.
Thus current limit is above 2Amps at 0.05+0.02 Ohms, Rsense + RFET. FET is CSD85302L.
COUT is LOW at -0.1V on V- =OK.
Over/Under voltage 2.8 to 4.28V is OK.
Please investigate…
