Hi
We are looking to use BQ29706 for a design powered with a single lifepo4 cell.
Design requirements
Continuous Charge current < 0.5A
Continuous Discharge current < 5A
As per the datasheet, OCC and OCD depend on the Rds(on) of the charge and discharge fets.
As per the calculations
Rds(on) = 40mohms and with that Pd = 1W in Discharge mode but during SCD the power will be around 9W and I am not able to find a MOSFET that certainly meets all the requirements
what should be the pulsating current and all other MOSFET parameters what do we need to consider and recommend general specifications of the MOSFET that can work for my application? and what is the layout recommendations for the Shortciruit current?
