Why Procurement Teams Source TDA21570

Buyers normally source TDA21570 when an existing BOM requires the same manufacturer suffix for automotive, motor-drive and power-stage sourcing. 10,000 pcs is listed as production-oriented spot stock; LimChip should confirm live allocation, batch condition and lead time before purchase. Suited to buyers needing the exact TDA21570 ordering code — the 70A OptiMOS power stage in PG-IQFN-39 — rather than a generic power stage.

LimChip can confirm current price, date code, packing condition, lot traceability and shipment schedule for TDA21570.

Power Component Sourcing Checklist

Confirm voltage, current, thermal rating and protection features against the original BOM.
Match PG-IQFN-39 (PQFN 5 mm × 6 mm), reel format and automotive or industrial grade requirements when needed.
Confirm live allocation, quantity and 26+ before order release.

TDA21570 (70A OptiMOS power stage) is offered from stock; live quantity and lot split are confirmed by RFQ.
