IN1
Battery Monitor Input 2. Connect to an external resistive divider to set the trip
threshold for monitor 2.
Battery Monitor Input 3. Connect to an external resistive divider to set the trip
threshold for monitor 3.
Battery Monitor Input 4. Connect to an external resistive divider to set the trip
threshold for monitor 4.
Reference Output. REF can source up to 1mA. REF does not require an external
bypass capacitor for stability. Keep the capacitance from REF to GND below 50pF.
Hysteresis Adjustment Input 1.
Connect HADJ1 to GND to select an internal preset hysteresis option.
Connect a resistive divider from REF to HADJ1 and to GND to externally adjust the
hysteresis for IN1 from its internal preset hysteresis (see Figure 6).
Hysteresis Adjustment Input 2.
Connect HADJ2 to GND to select an internal preset hysteresis option.
Connect a resistive divider from REF to HADJ2 and to GND to externally adjust the
hysteresis for IN2 from its internal preset hysteresis (see Figure 6).
Hysteresis Adjustment Input 3.
Connect HADJ3 to GND to select an internal preset hysteresis option.
Connect a resistive divider from REF to HADJ3 and to GND to externally adjust the
hysteresis for IN3 from its internal preset hysteresis (see Figure 6).
Hysteresis Adjustment Input 4.
Connect HADJ4 to GND to select an internal preset hysteresis option.
Connect a resistive divider from REF to HADJ4 and to GND to externally adjust the
hysteresis for IN4 from its internal preset hysteresis (see Figure 6).
Active-Low, Low-Battery Output 4. LBO4 asserts when VIN4 falls below the falling
threshold voltage. LBO4 deasserts when VIN4 exceeds the rising threshold voltage.
Active-Low, Low-Battery Output 3. LBO3 asserts when VIN3 falls below the falling
threshold voltage. LBO3 deasserts when VIN3 exceeds the rising threshold voltage.
Active-Low, Low-Battery Output 2. LBO2 asserts when VIN2 falls below the falling
threshold voltage. LBO2 deasserts when VIN2 exceeds the rising threshold voltage.
Active-Low, Low-Battery Output 1. LBO1 asserts when VIN1 falls below the falling
threshold voltage. LBO1 deasserts when VIN1 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.
Ground
No Connection. Not internally connected.
Battery Monitor Input 1. Connect to an external resistive divider to set the trip
threshold for monitor 1.
