5. Open the cell simulator switches, if needed When using external balancing with P-channel MOSFETs, such as on the bq76930 and bq76940 EVMs, the inrush current for a cell can momentarily turn on the balance FET causing the next cell input below to rise. -
Page 30: Connecting To A Host
Connecting to a Host After initial operation of the AFE with the bq76940/bq76930/bq76920 software, it may be desirable to operate the board connected to a microcontroller board. J14 can be used to connect to the microcontroller board. No voltages should be applied to the gauge terminals. Alternately, the microcontroller could be connected to the signal test points or J8 and the ALERT test point. -
