DETAILED DESCRIPTION
OVERVIEW
The TPS3779 and TPS3780 belong to a family of ultrasmall, low quiescent current (ICC), dual-channel voltage
detectors. These devices have high-accuracy, rising and falling input thresholds, and assert the output as shown
in Table 1. The output (OUTx pin) goes low when the SENSEx pin is less than VIT– and goes high when the pin
is greater than VIT+. The TPS3779 and TPS3780 offer multiple hysteresis options from 0.5% to 10% for use in
wide variety of applications. These devices have two independent voltage detection channels that can be used in
systems where multiple voltage rails are required to be monitored, or where one channel can be used as an early
warning signal and the other channel used as the system reset signal.

INPUTS (SENSE1, SENSE2)
The TPS3779 and TPS3780 have two comparators for voltage detection. Each comparator has one external
input; the other input is connected to the internal reference. The comparator rising threshold is designed and
trimmed to be equal to VIT+ and the falling threshold is trimmed to be equal to VIT–. The built-in falling hysteresis
options make the devices immune to supply rail noise and ensures stable operation.
The comparator inputs can swing from ground to 6.5 V, regardless of the device supply voltage used. Although
not required in most cases, it is good analog design practice to place a 1-nF to 10-nF bypass capacitor at the
comparator input for extremely noisy applications in order to reduce sensitivity to transients and layout parasitic.
For each SENSE input, the corresponding output (OUTx) is driven to logic low when the input voltage drops
below VIT–. When the voltage exceeds VIT+, the output (OUTx) goes to a high-impedance state, as shown in
Figure 13.
