Overview
The TB6600FG is a bipolar sine micro-step stepper motor driver IC manufactured by Toshiba Semiconductor and Storage. It utilizes power MOSFET technology to drive two-phase bipolar stepper motors with an output current of 4 A. The device supports multiple step resolutions including 1, 1/2, 1/4, 1/8, and 1/16 steps. It operates within a load voltage range of 8 V to 42 V and functions at temperatures between -30°C and +85°C. The component is housed in a 64-HQFP (10x10) surface-mount package.
Feature Summary
- Integrates full control and power stages for bipolar stepper motor applications
- Supports five selectable micro-step resolution modes for smooth operation
- Includes built-in protection circuits such as thermal shutdown and under-voltage lockout
Applications
- General purpose stepper motor control systems
- Automation equipment requiring precise positioning
- Industrial machinery utilizing bipolar stepper actuators
Procurement Notes
Verify the specific ordering suffix and manufacturer part number against official Toshiba documentation to ensure compatibility with required packaging and specifications. Confirm that the selected variant matches the intended application requirements regarding voltage, current, and interface signals before procurement.
Selection Notes
Select this component when a surface-mount solution is required for driving bipolar stepper motors with up to 4 A output current. Ensure the design accommodates the 64-HQFP package dimensions and thermal dissipation needs. Verify that the system voltage falls within the specified 8 V to 42 V operating range.
Part Context
This part belongs to Toshiba's line of motor drivers and controllers. It is designed for applications requiring integrated control and power stages. The TB6600FG offers a compact surface-mount alternative to through-hole variants like the TB6600HG, maintaining similar functional capabilities within a different physical footprint.
Replacement Considerations
The TB6600HG is a documented substitute offering identical functionality in a through-hole HZIP-25 package. When replacing the TB6600FG with the TB6600HG, verify PCB layout changes due to the difference in package type and pin configuration.
