Overview

The TLV3702IP is a dual-channel, nanopower comparator designed for battery-critical applications. It features a push-pull CMOS output stage and rail-to-rail input capabilities, allowing it to interface directly with digital logic without requiring external pull-up resistors. With a maximum quiescent current of just 1uA per channel, it is optimized for long-term monitoring in remote or portable systems.

Why Choose This Part

The primary advantage is its extremely low 1uA maximum quiescent current combined with a wide operating voltage range of 2.7V to 16V. It offers high reliability in industrial environments with a high CMRR of 88dB and PSRR of 105dB. The push-pull output simplifies PCB design by eliminating the need for pull-up resistors required by open-drain alternatives.

Applications

Portable Battery Monitoring
Used in undervoltage lockout and low-battery detection circuits where minimal current draw is essential to preserve battery life.
Consumer Medical Electronics
Ideal for wearable devices and handheld diagnostic tools that require high-impedance sensing and low power consumption.
Remote Security Sensors
Provides efficient threshold detection for motion, glass-break, or window sensors operating on coin-cell batteries.

Getting Started

Designers can evaluate this part on a breadboard using the 8-PDIP through-hole package. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VDD pin to maintain stability during output transitions. For rapid prototyping, generic 8-pin DIP to SOT-23 adapter boards can be used if migrating to surface-mount production variants later.
