Comparator Hysteresis
The MAX1614 contains an on-chip comparator with 2%
hysteresis for low-battery detection. If more than 2%
hysteresis is needed on the low-battery comparator and
LBO
is connected to
OFF,
use the circuit in Figure 5 to
add hysteresis. The circuit of Figure 5 shows
LBO
con-
trolling an N-channel MOSFET that shorts R2 to add
positive feedback to the trip point. This is necessary to
prevent loading down the 1μA pull-up at
OFF
