Overview

The TLV3702IDGKR is a dual-channel, nanopower comparator designed for ultra-low power monitoring applications. It features a push-pull, rail-to-rail output stage and operates with a maximum quiescent current of just 1uA, making it ideal for systems where power conservation is critical. The device supports a wide supply range from 2.7V to 16V and includes integrated reverse battery protection.

Why Choose This Part

The primary advantage is the exceptionally low power consumption of 560nA per channel, which significantly extends battery life in portable electronics. Its rail-to-rail input capability and wide 16V supply range offer flexibility in high-side sensing, while the push-pull output eliminates the need for external pull-up resistors.

Applications

Battery Voltage Monitoring
Ideal for low-battery detection in handheld devices due to the sub-microamp current draw.
Threshold Detection
Used in power-on reset circuits and window comparators where high CMRR (88dB) ensures signal integrity.
Remote Sensor Nodes
Provides low-power signal conditioning for environmental sensors in energy-harvesting applications.
System Wake-up Circuits
Acts as an always-on monitoring element to wake up high-power MCUs from sleep modes.

Getting Started

To evaluate this component, design a PCB with the 8-VSSOP footprint and ensure a 0.1uF bypass capacitor is placed close to the VDD pin. Since it features a push-pull output, it can be interfaced directly to digital logic inputs without additional passive components. Use a standard breadboard adapter if prototyping with the VSSOP package.
