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
Reverse-Battery Protection
To protect the LTC2951 from a reverse-battery connec-
tion, place a 1k resistor (R8) in series with the V
(see Figure 10).
