TYPICAL APPLICATIONS
External Pull-Up Resistor On PB
An internal pull-up resistor on the PB pin makes an ex-
ternal pull-up resistor unnecessary. Leakage current on
the PB board trace, however, will affect the open circuit
voltage on the PB pin. If the leakage is too large (>2μA),
the PB voltage may fall close to the threshold window. To
mitigate the effect of the board leakage, a 10k resistor to
V

is recommended (see Figure 9).

Reverse Battery Protection
To protect the LTC2954 from a reverse battery connec-
tion, place a 1k resistor in series with the V
