LM393BIPWR

Overview

The LM393BIPWR is a dual differential comparator manufactured by Texas Instruments, housed in an 8-pin TSSOP surface-mount package. It operates on a single power supply ranging from 2V to 30V or dual supplies up to ±15V. The device features open-collector outputs compatible with CMOS and TTL logic families. Key electrical specifications include a maximum input offset voltage of 7.5mV at 25°C, a typical propagation delay of 1.3µs, and a quiescent current of 0.5mA per channel. It supports a common-mode input voltage range extending to ground.

Feature Summary

• Dual differential comparators integrated into a compact TSSOP-8 package
• Open-collector output configuration ensuring compatibility with various logic families
• Wide single-supply operating voltage range from 2V to 30V
• Input common-mode voltage range includes ground potential

Applications

• Temperature sensing circuits
• Voltage monitoring systems
• Supervisory threshold detection

Procurement Notes

Verify the 'B' suffix indicates the B-grade specification variant, specifically noting the tighter input offset voltage tolerance compared to standard grades. Confirm the IPWR suffix corresponds to the TSSOP-8 tape-and-reel packaging format. Ensure the component meets RoHS compliance requirements for the specific manufacturing batch before integration.

Selection Notes

Select this component when low power consumption and wide supply voltage flexibility are required. The B-grade rating offers improved offset voltage performance suitable for precision applications. The TSSOP-8 package is ideal for space-constrained designs requiring surface-mount technology. Verify that the open-collector output architecture aligns with the pull-up resistor requirements of the downstream circuitry.

Part Context

This part belongs to the LM393 family of low-power dual comparators. It serves as a general-purpose analog comparator solution within Texas Instruments' portfolio. The device is designed for applications requiring efficient voltage comparison with minimal power draw. It shares functional similarities with other members of the series but differs in grade-specific electrical characteristics and packaging options.

Replacement Considerations

LM393IPWR: Standard grade equivalent with identical pinout and functionality but higher input offset voltage. LM2903-Q1: Automotive-grade alternative offering enhanced reliability standards for automotive environments while maintaining similar electrical characteristics.
