Part Number:BQ2970
Hi!
1. I need to add a function of enable and disable of BQ2970 by external signal. If BQ2970 is disabled then output voltage has to be 0V. If BQ2970 is enabled then it works in normal mode.
I am asking of the best way how to do it. I am thinking of three solution:
a) Connecting / disconnecting the "Vss" (pin 4) by external Mosfet N transistor.
b) Connecting / disconnecting the "BAT" (pin 5) by external Mosfet P transistor.
c) Connecting / disconnecting signals "Cout" and "Dout" by external transistors
2. The second question, why PCM try to reset output few times before permanently shut down? The CSD17306Q5A transistors are used in my solution. The two 5,1M Ohm resistors are assembled.
Yellow - cell voltage
Green - discharging current (voltage drop of 5m Ohm resistor)
Blue - short circuit signal
