Hi TI team,
My development work involves trying to control the BQ76942 via hardware.
We wanted a control that allows turning it on and off.
Having read the datasheets I have this solution below and wanted to confirm it will work?
The pins of concern are REG18, RST_SHUT and TS2.
In normal operation both the REG18 and RST_SHUT are switched to ground. This leads to the Normal mode.
To shutdown the operator switches the DPDT switch
As the second contact for both switches have no potential:
RST_SHUT will receive the 1.8V from REG18 which after 1 second will cause the BMS to shutdown.
There is a 1MegaOhm resistor used to prevent overload of REG18.
TS2 is floating to avoid soft shutdown.
