8.3.9 BP Switch-over

If the voltage on the BPEXT pin is lower than the switch-over voltage, VBPEXT(swover), then the internal BP6 regulator is used. If the voltage on the BPEXT pin exceeds this switch-over voltage, then the internal BP6 regulator is bypassed and the BP6 pin follows BPEXT, until the voltage on the BPEXT pin falls by the BPEXT switch-over hysteresis amount, VHYS(swover).

If the BPEXT function is not used, it is recommended to connect the BPEXT pin to GND via a 10 kΩ resistor to increase noise immunity.
