TC78S122FNG,EL

Overview

The TC78S122FNG,EL is a fully integrated bipolar stepper motor driver manufactured by Toshiba Semiconductor and Storage. It utilizes power MOSFET technology to deliver an output current of 2A with a supply voltage range of 4.5V to 5.5V and load voltages from 8V to 38V. The device supports step resolutions of 1, 1/2, and 1/4 steps via parallel interface control. Housed in a 48-HTSSOP package with exposed pad, it operates within a junction temperature range of -20°C to 150°C.

Feature Summary

Integrates full control logic and power stages for bipolar stepper motors
Supports selectable step resolutions including full, half, and quarter stepping
Utilizes power MOSFET output configuration for efficient drive capability

Applications

General purpose bipolar stepper motor control
Integrated motion control systems requiring compact packaging
Applications utilizing parallel interface command signals

Procurement Notes

Verify the specific ordering suffix EL against the manufacturer's latest datasheet to ensure correct packaging and material specifications. Confirm that the 48-HTSSOP exposed pad thermal requirements align with the target PCB layout design. Check RoHS3 compliance status and moisture sensitivity level classifications prior to assembly planning.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required. Ensure the system can accommodate the 4.5V to 5.5V logic supply and up to 38V load voltage. Verify that the parallel interface protocol matches the host controller outputs. Consider the 48-pin form factor for available board space constraints.

Part Context

This part belongs to the TC78S122 series of motor drivers designed for precision motion applications. It represents a consolidated approach to stepper motor driving by combining gate drive, logic, and protection circuits into one semiconductor package. The series targets designs needing reliable bipolar control without external discrete power components.
