I/O DESCRIPTION NAME DRY DBV GND 2 5 — Ground OUT1 is the output for SENSE1. OUT1 is asserted (driven low) when the voltage at SENSE1 falls below VIT–. OUT1 is deasserted (goes high) after SENSE1 rises higher than VIT+. OUT1 is a push-pull output for the TPS3779 OUT1 5 2 O and an open-drain output for the TPS3780. The open-drain device (TPS3780) can be pulled up to 6.5 V independent of VDD; a pull-up resistor is required for this device. OUT2 is the output for SENSE2. OUT2 is asserted (driven low) when the voltage at SENSE2 falls below VIT–. OUT2 is deasserted (goes high) after SENSE2 rises higher than VIT+. OUT2 is a push-pull output for the TPS3779 OUT2 4 3 O and an open-drain output for the TPS3780. The open-drain device (TPS3780) can be pulled up to 6.5 V independent of VDD; a pull-up resistor is required for this device. This pin is connected to the voltage to be monitored with the use of an SENSE1 1 6 I external resistor divider. When the voltage at this pin drops below the threshold voltage (VIT–), OUT1 is asserted. This pin is connected to the voltage to be monitored with the use of an SENSE2 3 4 I external resistor divider. When the voltage at this pin drops below the threshold voltage (VIT–), OUT2 is asserted. Supply voltage input. Connect a 1.5-V to 6.5-V supply to VDD in order to VDD 6 1 I power the device. Good analog design practice is to place a 0.1-µF ceramic capacitor close to this pin (required for VDD < 1.5 V).
