Frequently asked questions
What is the closest functional second-source for TB67S109AFTG,EL?
The TB67S109AFNG,EL is a near-identical sibling — same output current (3 A), same load voltage range (10 V to 47 V), same half-bridge configuration, same microstep resolution (1/32), and same package (48-WQFN). The only difference is the suffix (FTG vs FNG), which may reflect a minor process or ordering variant; the two parts are functionally interchangeable in the same PCB footprint.
