Hi all,
Considering the MAX77960B for a new design. I see that the charge parameters can be set in autonomous mode (via resistors) and these can then be subsequently over written with I2C to change limits.
The I2C description specifically states that you can NOT use I2C to return to autonomous mode.
Q. How can the device be reset/return to autonomous mode, and can this be achieved *without* processor being involved?
The reason I am asking is that I am concerned that a Type-C PD lease may be revoked/updated whilst the processor is sleeping (planning to use a stand-alone Port controller), and I want to ensure that the charger does not exceed the amount of power which will be available at any time.
My plan would be to configure autonomous charge to be set for 5V @ 900mA (ie minimum default power) and then have the processor up the settings according to actual lease.
I see that STBY (pin 19) can be asserted to prevent charging altogether, is this my only option for hardware control?
Thanks for advice/guidance,
Simon.
