Overview
The LP2901IDRQ1 is an automotive catalog quad, low-power, general-purpose differential comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V and features a maximum average input bias current of 0.025 µA at 25°C. The device has a maximum input offset voltage of 5000 µV and contains four functional channels. It is housed in a 14-pin SOIC package with dimensions of 8.65 mm length and is rated for operation between -40°C and 85°C.
Feature Summary
- Automotive-grade qualification for reliable performance in vehicle environments
- Low-power design suitable for battery-operated applications
- General-purpose differential comparison capability across wide supply ranges
Applications
- Automotive sensor signal conditioning
- Battery management system monitoring
- Industrial control circuit protection
Procurement Notes
Verify the specific suffix DRQ1 against official Texas Instruments documentation to confirm the exact package type, tape-and-reel quantity, and temperature grade. Ensure the component meets AEC-Q100 standards if required for your specific automotive application tier. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.
Selection Notes
Select this component when automotive reliability and low quiescent current are primary requirements. Compare the 5000 µV maximum offset voltage against LM2901 variants if higher precision is needed. Verify that the 14-SOIC package fits your PCB layout constraints and thermal management strategy compared to WQFN alternatives.
Part Context
This part belongs to the LP2901 family of low-power comparators designed for automotive use. It shares architectural similarities with the LM2901 series but includes specific enhancements for automotive durability and extended temperature stability. The Q1 suffix indicates compliance with automotive quality standards.
Replacement Considerations
LM2901IDRQ1 offers similar functionality with potentially different offset voltage specifications. LP2901N provides a through-hole alternative. Verify pinout compatibility and electrical parameter margins before substitution.
