EN

Active-Low Enable Input. Drive

EN low to turn on the voltage detectors. Drive EN high to force the

OUTA and OUTB outputs low.

EN

Active-High ENABLE Input. For the MAX16010/MAX16011, drive EN high to turn on the voltage

detectors. Drive EN low to force OUTA low and OUTB low (LOGIC = low) or high (LOGIC = high). For

the MAX16013/MAX16014, drive EN high to enhance the p-channel MOSFET (P2), and drive EN low

REF

Internal 1.30V Reference Output. Connect REF to IN+ for active-low output. Connect REF to IN- for

active-high output. REF can source and sink up to 1µA. Leave REF floating if not used. REF output is

stable with capacitive loads from 0 to 50pF.
