LM2901BIPWR

Overview

The LM2901BIPWR is a quad differential voltage comparator manufactured by Texas Instruments, housed in a 14-pin TSSOP package. It operates on a single supply voltage ranging from 2V to 36V. The device features an extended industrial temperature range of -40°C to +125°C and includes dedicated ESD clamps providing a ±2kV Human Body Model rating. Electrical characteristics include a maximum input offset voltage of ±5.5mV over the full temperature range, a typical quiescent current of 800µA to 1mA, and a propagation delay of 1µs.

Feature Summary

• Drop-in replacement for legacy LM239, LM339, and LM2901 devices
• Integrated ESD protection with ±2kV HBM rating
• Low input bias current and low supply current consumption
• Output compatible with TTL, MOS, and CMOS logic families

Applications

• Vacuum robots
• Single phase UPS systems
• Server power supplies
• Cordless power tools
• Wireless infrastructure equipment

Procurement Notes

Verify that the specific ordering suffix IPWR corresponds to the TSSOP-14 package variant. Confirm the B-version designation ensures the specified improved electrical parameters and extended temperature range are met. Ensure compatibility with existing PCB footprints designed for standard LM2901 or LM339 packages before finalizing procurement.

Selection Notes

Select this component when upgrading from older LM2901 or LM339 generations to benefit from lower offset voltage and faster response times. The wide supply voltage range supports both low-voltage battery applications and higher voltage industrial systems. Verify that the open-collector output configuration aligns with the pull-up requirements of the downstream circuitry.

Part Context

This device belongs to the LM2901B family, representing the next-generation iteration of the industry-standard LM2901 comparator series. It shares pinout compatibility with previous versions while offering enhanced performance metrics such as reduced propagation delay and improved input ruggedness through integrated electrostatic discharge protection mechanisms.
