LM2901QPWRG4HE

Overview

The LM2901QPWRG4HE is a quad differential comparator from Texas Instruments, designed for automotive applications. It features an open-collector output and operates on a single or dual power supply ranging from 2V to 30V (±1V to ±15V). The device is housed in a 14-TSSOP package with a width of 4.40mm. It supports an operating temperature range of -40°C to +125°C and draws a maximum static current of 2.5mA. The input offset voltage is typically 7mV at 5V, with an input bias current of 250nA.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Quad differential configuration for multi-channel signal processing
• Open-collector output compatible with CMOS and TTL logic families

Applications

• Automotive electronic control units
• General-purpose analog signal comparison
• Voltage threshold detection circuits

Procurement Notes

Verify the specific suffix HE against official Texas Instruments documentation to confirm it denotes a prototype or specific variant status distinct from standard production parts like QDRQ1 or QPWRG4Q1. Ensure the component meets all required automotive reliability standards before integration into final designs.

Selection Notes

Select this component when automotive durability and wide supply voltage ranges are required. The TSSOP-14 package offers space efficiency for surface-mount assemblies. Consider the open-collector output requirements for pull-up resistor implementation in the circuit design.

Part Context

This part belongs to the LM2901 family of quad comparators. It shares functional similarities with other automotive-grade variants such as LM2901QDRQ1 and LM2901QPWRG4Q1, differing primarily in packaging or specific manufacturing lot characteristics defined by the manufacturer's internal coding.

Replacement Considerations

LM2901QPWRG4Q1 and LM2901QDRQ1 are confirmed public substitutes within the same automotive family.
