TILM393BIPWR
Overview
The LM393BIPWR is a next-generation version of the industry-standard LM393 dual comparator, designed for improved performance in general-purpose voltage monitoring. It features two independent voltage comparators in a compact 8-TSSOP package, capable of operating from a wide supply range of 2V to 36V. The open-collector output architecture allows for easy level shifting and logical wired-AND connections in mixed-voltage systems.
Why Choose This Part
This 'B' version provides significant upgrades over the original LM393, including a higher supply voltage rating up to 36V and a lower input offset voltage. The 1us typical propagation delay and 600uA maximum quiescent current make it a reliable choice for power-sensitive and high-speed switching tasks.
Applications
Key Specifications
Getting Started
To implement the LM393BIPWR, ensure a pull-up resistor is connected to the open-collector output to define the high-level logic voltage. Prototyping can be performed using standard 8-pin TSSOP-to-DIP adapter boards on a breadboard. Observe proper decoupling with a 0.1uF capacitor placed close to the VCC pin to minimize switching noise.
