Overview
The LM2901QPWRQ1 is a quad differential analog comparator designed for automotive applications, certified to AEC-Q100 standards. It operates within a supply voltage range of 2 V to 36 V and features open-collector outputs compatible with CMOS and TTL logic families. The device supports single or dual power supplies, with a maximum quiescent current of 2.5 mA per channel. It includes four independent comparators in a 14-TSSOP package, offering a typical response time of 1.3 µs and an input offset voltage of 7 mV at 5 V.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
- Quad differential architecture providing four independent comparison channels in a compact surface-mount package.
- Wide single-supply operating range from 2 V to 36 V, supporting diverse power system configurations.
Applications
- Automotive battery monitoring systems
- General-purpose signal processing in vehicle electronics
- Over-voltage and under-voltage detection circuits
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Confirm that the AEC-Q100 qualification level meets your specific automotive application requirements before finalizing procurement.
Selection Notes
Select this component when automotive reliability is mandatory and a wide supply voltage range is needed. The open-collector output requires external pull-up resistors, which must be accounted for in the design. Compare the 1.3 µs response time against system speed requirements to ensure adequate performance for the intended signal frequencies.
Part Context
This device belongs to the LM2901 family of quad comparators. The 'Q1' suffix indicates automotive qualification, while 'PWR' specifies the 14-TSSOP package. It serves as a robust alternative to standard commercial comparators in harsh automotive environments, offering similar electrical characteristics with enhanced durability and temperature stability.
Replacement Considerations
LM2901QPWRG4Q1 is a verified equivalent part number representing the same functional device with updated manufacturing specifications.
