Toshiba's original ADMD technology tracks input current more closely than the conventional mixed-decay mode, making highly efficient motor control possible at high rpm.
Products incorporating the ADMD technology:
TB67S101A TB67S102A TB67S103A TB67S105 TB67S109A TB67S261 TB67S265 TB67S269
Toshiba's original ACDS technology enables motor drive with highly accurate constant current without requiring external current-sensing resistors.
The reduced part count also helps reduce the board area and the bill-of-material (BOM) cost.
Products incorporating the ACDS technology：
TB67S141 TB67S142 TB67S145 TB67S149 TB67S179
Fabricated using a state-of-the-art high-voltage analog process (130-nm BiCD process), Toshiba's stepping motor drivers combine low-voltage control circuitry with high-voltage DMOS output drivers on the same monolithic structure. Consequently, high-voltage motor drivers rated at 84 V can be housed in the small WQFN48 (7 mm × 7 mm) package, which helps reduce the solution size.
