Supply Voltage Input. Connect a 2.2V to 28V supply voltage to power the
device. All outputs are low when V_CC is below the UVLO. For noisy systems,
bypass V_CC to GND with a 0.1µF capacitor.
Monitored Input 1. When the voltage at IN1 exceeds its threshold, OUT1 goes
high after the capacitor-adjustable delay period. When the voltage at IN1 falls
below its threshold, OUT1 goes low after a propagation delay.
Monitored Input 2. When the voltage at IN2 exceeds its threshold, OUT2 goes
high after the capacitor-adjustable delay period. When the voltage at IN2 falls
below its threshold, OUT2 goes low after a propagation delay.
Monitored Input 3. When the voltage at IN3 exceeds its threshold, OUT3 goes
high after the capacitor-adjustable delay period. When the voltage at IN3 falls
below its threshold, OUT3 goes low after a propagation delay.
Monitored Input 4. When the voltage at IN4 exceeds its threshold, OUT4 goes
high after the capacitor-adjustable delay period. When the voltage at IN4 falls
below its threshold, OUT4 goes low after a propagation delay.
Threshold Tolerance Input. Connect TOL to GND to select thresholds 5%
below nominal. Connect TOL to V_CC to select thresholds 10% below nominal.
Ground
Active-High Logic-Enable Input 1. Driving EN1 low causes OUT1 to go low
regardless of the input voltage. Drive EN1 high to enable the monitoring
comparator.
Active-High Logic-Enable Input 2. Driving EN2 low causes OUT2 to go low
regardless of the input voltage. Drive EN2 high to enable the monitoring
comparator.
Active-High Logic-Enable Input 3. Driving EN3 low causes OUT3 to go low
regardless of the input voltage. Drive EN3 high to enable the monitoring
comparator.
Active-High Logic-Enable Input 4. Driving EN4 low causes OUT4 to go low
regardless of the input voltage. Drive EN4 high to enable the monitoring
comparator.
Threshold Select Input 1. Connect TH1 to V_CC or GND, or leave it open to
select the input-voltage threshold option in conjunction with TH0 (see Table 2).
Threshold Select Input 0. Connect TH0 to V_CC or GND, or leave it open to
select the input-voltage threshold option in conjunction with TH1 (see Table 2).
Output 4. When the voltage at IN4 is below its threshold or EN4 goes low,
OUT4 goes low.
Output 3. When the voltage at IN3 is below its threshold or EN3 goes low,
OUT3 goes low.
Output 2. When the voltage at IN2 is below its threshold or EN2 goes low,
OUT2 goes low.
