INA240PMPWPSEP

Overview

The INA240PMPWPSEP is a space-enhanced, high- and low-side, bidirectional current-sense amplifier manufactured by Texas Instruments. It features a wide common-mode voltage range of -4 V to 80 V and utilizes a zero-drift architecture for high precision. The device operates on a single supply voltage between 2.7 V and 5.5 V with a maximum supply current of 2.4 mA. It provides enhanced PWM rejection capabilities to handle large common-mode transients in motor drive and solenoid applications. The component is housed in an 8-pin plastic package designed for space-constrained environments.

Feature Summary

• Space-enhanced plastic construction suitable for aerospace and defense applications
• Zero-drift architecture ensures high accuracy with minimal offset voltage drift over temperature
• Enhanced PWM rejection capability effectively suppresses output transients caused by rapid common-mode changes
• Bidirectional operation allows current sensing in both directions across a wide common-mode voltage range

Applications

• Aerospace and satellite power distribution systems
• Defense electronics requiring radiation-tolerant or space-grade components
• High-reliability industrial motor control systems
• Precision current monitoring in harsh environmental conditions

Procurement Notes

Verify the specific revision level and lot traceability documentation required for your project's quality standards. Ensure that the space-enhanced packaging meets your mechanical and thermal constraints. Confirm compatibility with your assembly processes regarding lead-free specifications and moisture sensitivity levels. Review the datasheet for any handling precautions specific to space-grade components.

Selection Notes

Select this part when standard commercial grade amplifiers do not meet the reliability requirements of your application. The zero-drift technology is critical for maintaining accuracy without frequent calibration. Consider the -4 V to 80 V common-mode range if your system operates below ground or at high voltages. Evaluate the enhanced PWM rejection if your design involves noisy switching environments.

Part Context

This component belongs to the INA240 family of current-sense amplifiers from Texas Instruments. While the standard INA240 series is widely used in industrial applications, the PMPWPSEP suffix indicates a specialized version optimized for space environments. It shares core electrical characteristics with the commercial variants but differs in manufacturing processes and qualification standards to withstand the rigors of space operations.

Replacement Considerations

Direct replacements are limited due to the space-enhanced nature of this part. Standard INA240 variants (e.g., INA240A2PWR) may fit electrically but lack the necessary space qualification. Check for other TI space-grade components in the same family if gain configurations differ.
