NAME FUNCTION
1 1 — — — GND2
Reserved. Must be connected to GND. Do not use as the only
GND connection.
2 2 2 2 2 GND Ground
3 3 — — — LBI
Low-Battery Input. Connect to the resistive divider to set the
trip level.
4 4 4 4 — LBO
Low-Battery Output, Active-Low. When V LBI /V LBL falls below
the falling threshold, LBO asserts. LBO deasserts when
V
LBI
/V
LBH
exceeds the rising threshold voltage.
5 — 5 — — N.C. No Connection. Not internally connected.
6 5 6 5 6 BATT Battery Input. Power supply to the device.
— — 1 1 — LBH
Rising-Trip-Level Input. Connect to a resistive divider to set the
rising trip level.
— — 3 3 — LBL
Falling-Trip-Level Input. Connect to a resistive divider to set the
falling trip level.
— — — — 1 LBI2
Low-Battery Input 2. Connect to a resistive divider to set the
trip level.
— — — — 3 LBI1
Low-Battery Input 1. Connect to a resistive divider to set the
trip level.
— — — — 4 LBO1
Low-Battery Output 1, Active-Low. When V LBI1 falls below the
falling threshold voltage, LBO1 asserts. LBO1 deasserts when
V
LBI1 exceeds the rising threshold voltage. LBO1 is push-pull
on the MAX6781 and open-drain for the MAX6779/MAX6780.
— — — — 5 LBO2
Low-Battery Output 2, Active-Low. When V LBI2 falls below the
falling threshold voltage, LBO2 asserts. LBO2 deasserts when
V
LBI2
exceeds the rising threshold voltage. LBO2 is open-drain.
