2.3.8.1 Configuration Jumpers

Certain features on the BQ76905EVM can be configured by jumpers or shunts on headers. See Section 5.1 for details of the header pins.

J1 and J5 connect the BQ76905 I2C lines to pull-up resistors at REGOUT for off-board MCU communications.

J2 and J6 connect the I2C lines of the BQ76905 to the on-board MCU.

J7 connects the ALERT pin to a pull-up resistor at REGOUT.

J8 connects/disconnects the on-board thermistor from the TS pin.

J10 cell simulator connections.

The cell simulator headers and are discussed in board connection diagrams.
