MAX1614
High-Side, n-Channel MOSFET
Switch Driver
Increasing Low-Battery
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 pos-
itive feedback to the trip point. This is necessary to
prevent loading down the 1μA pullup at OFF (Figure 1).
