PIN FUNCTIONS
BLOCK DIAGRAM
LTC2931
COMP2 (Pin 18): Comparator Output 2. Real-time logic
output with weak 6μA pull-up to V2. Pulls high when V2
is above its reset threshold. May be pulled greater than
V2 using external pull-up. Leave open if unused.
V6 (Pin 19): Adjustable Voltage Input 6. High impedance
comparator input with 0.5V typical threshold. See
Applications Information for details. Tie to V1 if unused.
