FUNCTION
Falling Trip Level Input 1. Connect to an external resistive divider to set the falling trip level.
Rising Trip Level Input 1. Connect to an external resistive divider to set the rising trip level.
Falling Trip Level Input 2. Connect to an external resistive divider to set the falling trip level.
Rising Trip Level Input 2. Connect to an external resistive divider to set the rising trip level.
Ground
Active-Low, Low-Battery Output 2. LBO2 asserts when V LBL2 falls below the falling threshold voltage. LBO2
deasserts when V LBH2 exceeds the rising threshold voltage.
Active-Low, Low-Battery Output 1. LBO1 asserts when V LBL1 falls below the falling threshold voltage. LBO1
deasserts when V LBH1 exceeds the rising threshold voltage.
Battery Input. Power supply to the device. For better noise immunity, bypass BATT to GND with a 0.1μF
capacitor as close to the device as possible.
Exposed Pad. Connect EP to the ground plane. Do not use EP as the only ground connection.

FUNCTION
Overvoltage Monitor Input 1
Overvoltage Monitor Input 2
Overvoltage Monitor Input 3
Overvoltage Monitor Input 4
Ground
Active-Low Clear Input. OV and OV do not latch when an overvoltage fault is detected if CLEAR is held low.
CLEAR has an internal pullup resistor to BATT.
No Connection. Not internally connected.
Active-Low Overvoltage Output. When any of the inputs (V IN_ ) exceeds its respective rising threshold
voltage, OV asserts and stays asserted until CLEAR is pulled low or the power to the device is cycled. OV
does not latch when an overvoltage fault is detected if CLEAR is held low.
Active-High Overvoltage Output. Inverse of OV .
Battery Input. Power supply to the device. For better noise immunity, bypass BATT to GND with a 0.1μF
capacitor as close to the device as possible.
Exposed Pad. Connect EP to the ground plane. Do not use EP as the only ground connection.
Detailed Description
The MAX6782–MAX6788 are designed to monitor two
to four battery levels (1% accuracy) and assert an
active-low output indicator when the monitored voltage
level falls below the user-set threshold. Each battery
level is associated with an independent open-drain or
push-pull output. Each of these independent outputs
can be used to provide low battery warnings at differ-
ent voltage levels. Each of these monitored levels offers
fixed or adjustable hysteresis in order to prevent the
output from chattering as the battery recovers from the
lighter loads. The MAX6782–MAX6785 also feature ref-
erence outputs that can source up to 1mA.
The MAX6789/MAX6790 monitor four overvoltage con-
ditions and assert the complementary overvoltage out-
puts when any voltage at the inputs exceeds its
respective threshold. The MAX6789/MAX6790 allow
each trip threshold to be set with external resistors.
These devices also feature a latch and a clear function.
Figures 1, 2, and 3 show the simplified block diagrams
for the MAX6782–MAX6790. See the Selector Guide.
