Overview
The LM393WPT is a dual low-power voltage comparator manufactured by ROHM Semiconductor, housed in an 8-pin TSSOP package. It operates on a single supply from +2V to +36V or split supplies of ±1V to ±18V. The device features a typical supply current of 0.4mA and includes two independent comparators with open-collector outputs. Input common-mode voltage range extends to ground, allowing for ground sensing applications.
Feature Summary
- Operates with wide single-supply voltage ranges
- Features input/output ground sense capability
- Provides low power consumption characteristics
- Includes open collector output structure
Applications
- Consumer Electronics
- Current Sense Application
- Battery Monitor
- Multivibrator
Procurement Notes
Verify the specific suffix WPT corresponds to the TSSOP-8 (TSSOP-B8J) package configuration as defined in the ROHM datasheet. Confirm that the operating temperature range aligns with the -40°C to +85°C specification for the LM393 series before finalizing procurement specifications.
Selection Notes
Select this component when a dual comparator with low supply current is required for single-supply systems. Ensure the application utilizes open-collector outputs compatible with TTL, DTL, ECL, MOS, or CMOS logic levels. Verify that the input common-mode voltage requirements include ground potential within the operational range.
Part Context
This part belongs to the ROHM Signature Series of monolithic ICs integrating independent comparator circuits. It shares functional similarities with the LM2903xx, LM339xx, and LM2901xx families but is distinguished by its specific package type and commercial temperature rating.
Replacement Considerations
Public confirmed substitute part numbers include LM2903PT and LM339PT.
