It delivers an 800 kHz -3 dB bandwidth, which is sufficient for tracking load transients in switching power supplies and motor drive phases without significant phase lag. Supply current is 800 µA, keeping the quiescent overhead low in always-on monitoring paths.
The device is surface mounted in an 8-SOIC package, a standard footprint for board-level current-sense amplifiers.
It is ROHS3 compliant, suitable for lead-free assembly flows.
Design engineers need to verify compatibility with their power rails.
Sourcing buyers and brokers must know lifecycle status to avoid supply chain risks.
Transactional buyers need immediate availability for production or replacement.
Buyers compare prices across distributors for cost optimization.
Engineers and sourcing look for alternatives when the part is unavailable or for second sourcing.
Design and replacement technicians need physical dimensions and pin mapping for PCB layout and substitution.
