LP2901IDRG4Q1

Overview

The LP2901IDRG4Q1 is an automotive-grade, quad differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V and features a typical response time of 1.3 µs. The device includes four independent channels with open-collector outputs compatible with CMOS and TTL logic families. It maintains operation across an extended temperature range from -40°C to +125°C and adheres to AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive grade reliability certified under AEC-Q100 standards
• Quad differential architecture providing four independent comparison channels
• Wide single or dual power supply compatibility up to 36 V
• Open-collector output stage supporting CMOS and TTL interface levels

Applications

• Automotive sensor signal conditioning
• Voltage level monitoring in vehicle electronics
• General purpose analog-to-digital threshold detection

Procurement Notes

Verify the specific suffix 'DRG4' corresponds to the TSSOP-14 package variant when sourcing. Confirm that the Q1 designation indicates AEC-Q100 automotive qualification status. Ensure the component matches the intended thermal performance requirements for the target operating environment.

Selection Notes

Select this component for designs requiring multiple comparator functions within a compact surface-mount footprint. It is suitable for systems needing wide supply voltage tolerance and robust automotive environmental resilience. Consider the open-collector output requirement for external pull-up resistor implementation.

Part Context

This part belongs to the LM/LP2901 family of low-power quad comparators. The LP prefix typically denotes improved low-power characteristics compared to standard variants. The IDRG4Q1 suffix specifies the automotive qualification, TSSOP-14 packaging, and lead-free manufacturing process compliant with RoHS directives.
