Hi,
I have a system I am redesigning to use the npm1300.
It has a rechargeable battery, about 3-4 weeks per charge, connected to an nrf9160.
The current system has an external watchdog chip and also controls an RGB LED through 3 pwm pins
What timeout (or timeout range) does watchdog on the npm1300 have? Is it configurable through i2c?
Is it suitable to use as an external watchdog for the nrf9160?
Is it serviced over the I2C bus?
What (if any) additional power draw is used by the npm1300 if the watchdog is enabled?
For the LEDs, I see it has 3 led drivers. Is it suitable for an RGB led?
Are the led driver lines only on/off? Or do they pwm?
Is it possible to set the LEDs to blink, like if you want green to blink at 1 hz? Or would on/off command have to be sent to achieve blinking?
What power draw do the led drivers add?
