TA8428K/FG is a motor driver chip from Toshiba. It has four working modes: forward, reverse, stop, and brake. The maximum output current can reach 3.0A.
The TA8428K/FG IC provides a full‑bridge driver solution for brushed DC motors, allowing forward, reverse, stop and brake operation. It integrates a PNP voltage comparator, diode for back‑EMF absorption, and internal over‑current and thermal shutdown circuits.
The device operates from a 7.0 V to 27.0 V supply, delivers up to 3.0 A peak current (K type) or 2.4 A peak (FG type), and includes detailed pin descriptions, absolute‑maximum ratings, and example application circuits for motor control designs. This manual is written in Japanese.
