7.1 Overview

The TLV4062-Q1 and TLV4082-Q1 are small, low quiescent current (IDD), dual-channel comparators. These devices have high-accuracy, rising and falling input thresholds, and assert the output as shown in Table 7-1. The output (OUTx) transitions high when the input (INx) is rising and greater than VIT+; the output (OUTx) will remain high until the input is falling and drops below VIT- . The TLV4062-Q1 and TLV4082-Q1 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 can be used as the system reset signal.
