TILM393PWRG3

Overview

The LM393PWRG3 is a dual differential comparator IC designed to operate from a single power supply over a wide range of voltages. It features two independent voltage comparators with an open-collector output stage, allowing for easy interfacing with various logic levels. This specific variant is provided in a small TSSOP-8 package, suitable for space-constrained PCB designs.

Why Choose This Part

The device offers a very wide supply range from 2V to 36V, making it compatible with both low-voltage digital systems and higher-voltage industrial rails. Its open-collector output configuration allows for wired-OR connections and level shifting between different voltage domains. Furthermore, the common-mode input voltage range includes ground, facilitating direct sensing of low-side currents.

Applications

Getting Started

When designing with the LM393PWRG3, remember that the open-collector output requires an external pull-up resistor to define the high-level logic voltage. Prototyping is best done using a TSSOP-8 to DIP adapter on a breadboard or by integrating it into a custom PCB with decoupling capacitors placed close to the VCC pin. Ensure the input differential voltage does not exceed the absolute maximum ratings specified in the Texas Instruments datasheet.
