TC78S122FTG,EL

Overview

The TC78S122FTG,EL is a bipolar stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It integrates control logic and power stages using power MOSFET technology within a 48-HTSSOP package with exposed pad. The device supports step resolutions of 1, 1/2, and 1/4 steps. It operates with a supply voltage range of 4.5V to 5.5V and handles load voltages from 8V to 38V. The output current capability is rated at 2A per phase. The junction temperature range extends from -20°C to 150°C.

Feature Summary

Integrates full control and power stages for bipolar stepper motors
Supports multiple step resolutions including full, half, and quarter steps
Utilizes power MOSFET output configuration for efficient driving

Applications

General purpose stepper motor control systems
Automation equipment requiring precise positioning
Office automation devices

Procurement Notes

Verify the specific suffix FTG against EL when sourcing, as packaging or tape specifications may differ between distributors. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 48-HTSSOP footprint matches your PCB design constraints. Check official datasheets for thermal dissipation requirements given the exposed pad design.

Selection Notes

Select this component for applications requiring integrated bipolar stepper motor control with moderate current demands. The wide junction temperature range suits environments with thermal variations. Verify that the 2A output rating aligns with the connected motor's phase current requirements. Consider the 48-pin package size relative to available board space.

Part Context

This part belongs to the TC78S122 series of stepper motor drivers from Toshiba. It is designed for general-purpose applications where integrated control and power stages simplify system design. The family typically offers solutions for bipolar stepper motors with varying pin counts and current capabilities depending on the specific model variant.
