TB62214AFG,8,EL

Overview

The TB62214AFG,8,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes DMOS technology to provide integrated control and power stages for two-phase motors. The device supports full, half, and quarter step resolutions with a parallel interface. It operates within a supply voltage range of 4.75V to 5.25V and handles load voltages from 10V to 38V. The output current capability is rated at 2A per phase. The component is housed in a 48-QFN (7x7mm) package with an exposed pad for thermal management. It functions reliably across a junction temperature range of -20°C to 150°C.
