MAX1614 High-Side, n-Channel MOSFET Switch Driver
Increasing Low-Battery Comparator Chip Information Hysteresis
SUBSTRATE CONNECTED TO GND 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
