7 Detailed Description

7.1 Overview

The TLV3691 is a nano-power comparator with push-pull output. Operating from 0.9 V to 6.5 V and consuming a maximum quiescent current of only 200 nA over the temperature range from –40°C to 125°C, the TLV3691 is ideally suited for portable and industrial applications. The TLV3691 is available in the 5-pin SC70 and 6-pin DFN packages.

7.3 Feature Description

The TLV3691 features a nano-power comparator capable of operating at low voltages. The TLV3691 features a rail-to-rail input stage capable of operating up to 100 mV beyond each power supply rail. The TLV3691 also features a push-pull output stage with internal hysteresis.

7.4 Device Functional Modes

The TLV3691 has a single functional mode and is operational when the power supply voltage is greater than
0.9 V. The maximum power supply voltage for the TLV3691 is 6.5 V.

7.4.1 Nano-Power

The TLV3691 features nano-power operation. With a maximum of 150 nA of operating current at 25°C, the TLV3691 is ideally suited for portable and battery powered applications. With a maximum of 200 nA of operating current over the temperature range from -40°C to 125°C, the TLV3691 is also ideally suited for industrial applications and is a must have in every designer's toolbox.

7.4.2 Rail-to-Rail Inputs

The TLV3691 features an input stage capable of operating up to –100 mV beyond ground and 100 mV beyond the positive supply voltage, allowing for ease of use and flexible design options. Internal hysteresis of 17 mV (typical) allows for operation in noisy environments without the need for additional external components.

7.4.3 Push-Pull Output

The TLV3691 features a push-pull output, eliminating the need for an external pullup resistor and allows for nano-power operation across all operating conditions.
