Overview
The TB67S101AFNG,EL is a two-phase bipolar stepping motor driver utilizing a BiCD process. It features a PWM chopper for constant-current drive and supports full, half, and quarter step operations. The device integrates a low on-resistance MOSFET output stage with a typical value of 0.49Ω. Built-in error detection includes thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR). It operates within a load voltage range of 10V to 47V and accepts a logic supply of 4.75V to 5.25V. The component is housed in an HTSSOP-48 package.
Feature Summary
- Integrates advanced dynamic mixed decay mechanism for high-efficiency motor current control.
- Features a built-in VCC regulator specifically designed for internal circuit use.
- Supports customizable chopping frequency via external resistance and condenser components.
Applications
- Printer mechanisms
- Numerical control machine tools
- Industrial automation equipment
Procurement Notes
Verify the specific suffix EL against official Toshiba documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the required HTSSOP-48 footprint during PCB layout. Confirm that the design accommodates the specified thermal dissipation requirements for the selected operating conditions.
Selection Notes
Select this component when a fully integrated stepper driver with phase-in control interface is required. It is suitable for applications demanding high voltage and current ratings within a compact surface-mount package. Consider the available step resolutions and built-in protection features for robust system design.
Part Context
This part belongs to the TB67S101 series of stepping motor driver ICs from Toshiba Semiconductor and Storage. The series offers multiple package options including HSOP28, WQFN48, and HTSSOP48 variants. All members share the core BiCD technology and functional capabilities for controlling bipolar stepping motors.
Replacement Considerations
TB67S101AFTG,EL and TB67S101AFG,EL are confirmed substitutes within the same product family. These alternatives provide identical electrical performance but utilize different physical packages (WQFN48 and HSOP28 respectively). Verify mechanical fit and thermal management requirements before substitution.
