Reserved. Must be connected to GND. Do not use as the only

GND connection.

Ground

Low-Battery Input. Connect to the resistive divider to set the

trip level.

Low-Battery Output, Active-Low. When VLBI/VLBL falls below

the falling threshold, LBO asserts. LBO deasserts when

VLBI/VLBH exceeds the rising threshold voltage.

No Connection. Not internally connected.

Battery Input. Power supply to the device.

Rising-Trip-Level Input. Connect to a resistive divider to set the

rising trip level.

Falling-Trip-Level Input. Connect to a resistive divider to set the

falling trip level.

Low-Battery Input 2. Connect to a resistive divider to set the

trip level.

Low-Battery Input 1. Connect to a resistive divider to set the

trip level.

Low-Battery Output 1, Active-Low. When VLBI1 falls below the

falling threshold voltage, LBO1 asserts. LBO1 deasserts when

VLBI1 exceeds the rising threshold voltage. LBO1 is push-pull

on the MAX6779/MAX6781 and open-drain for the MAX6780.

Low-Battery Output 2, Active-Low. When VLBI2 falls below the

falling threshold voltage, LBO2 asserts. LBO2 deasserts when

VLBI2 exceeds the rising threshold voltage. LBO2 is open-drain

for the MAX6780/MAX6781 and push-pull for the MAX6779.
