Part Number: BQ25155

For the PBat power dissipation. If the load current is 1.5 A and the max Battery FET RdsOn = 135 mOhm. Is the power dissipation 303750 mW?

Hi,

If your are discharging from your battery to your system load, with a load current of 1.5A and a max BATFET RDSON of 135 mOhms, then your maximum power dissipation should be 202.5 mW.

Best Regard,
