Overview
The LM393PT is a dual voltage comparator manufactured by ROHM Semiconductor, housed in an 8-pin TSSOP package. It operates on a single supply from +2V to +36V or dual supplies of ±1V to ±18V. The device features two independent channels with open-collector outputs and supports ground-sensed inputs. Key electrical characteristics include a typical supply current of 0.4mA, input bias current of 25nA, and small signal response time of 1.3µs. The operating temperature range extends from -40°C to +85°C.
Feature Summary
- Operates with wide single or dual power supply voltages
- Features low supply current consumption
- Supports input common-mode voltage including ground level
- Provides open-collector output configuration
Applications
- Consumer Electronics
- Current Sense Application
- Battery Monitor
- Multivibrator
Procurement Notes
Verify the specific manufacturer designation for the LM393PT suffix, as it may vary between vendors such as ROHM or STMicroelectronics. Confirm that the component matches the required TSSOP-8 physical dimensions and pinout. Ensure the selected part meets the specified -40°C to +85°C operating temperature range for your application environment.
Selection Notes
Select this component when a low-power, dual-channel comparator is needed for single-supply operation. The open-collector output requires an external pull-up resistor to function correctly. Consider the input offset voltage and response time specifications against the precision and speed requirements of the target circuit design.
Part Context
This device belongs to the LM393 series of monolithic integrated circuits containing two independent comparators. It is designed for general-purpose voltage comparison tasks where low power consumption and wide supply voltage flexibility are prioritized. The TSSOP-8 package offers a compact solution for surface-mount applications.
