Overview

The TLC3702IP is a dual micropower voltage comparator featuring LinCMOS technology and a push-pull CMOS output stage. It is designed to operate from a single supply ranging from 3V to 16V, offering high input impedance and very low bias currents. This part is particularly useful for battery-powered systems where minimizing current consumption is critical.

Why Choose This Part

The primary advantage is the extremely low input bias current of 5pA, which allows for high-impedance sensing circuits without loading the source. The push-pull output eliminates the need for an external pull-up resistor, saving board space and reducing power consumption compared to open-drain alternatives.

Applications

Battery Supply Supervisors
Monitoring battery voltage levels with minimal current draw to trigger low-battery alerts.
Pulse-Width-Modulated Motor Control
Generating PWM signals for motor speed control in power-sensitive industrial designs.
Two-Phase Clock Generation
Creating non-overlapping clock signals for digital logic or switched-capacitor circuits.
Micropower Switching Regulators
Acting as the control element in low-power DC-DC converters to maintain regulation.

Getting Started

When prototyping, use the 8-pin PDIP package directly in a standard breadboard or IC socket. Ensure the input voltage stays within the specified range of -0.2V to 14.5V and decouple the VDD pin with a 0.1uF ceramic capacitor near the IC to minimize switching noise from the push-pull output stage.
