Product details
Overview
TB67S215FTAG from Toshiba is a PWM-controlled, clock-input bipolar stepping motor driver IC designed for two-phase stepper motors. It delivers 40 V/2.5 A absolute maximum output, supports full/half/quarter-step resolution, integrates thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on reset (POR), and operates from a single VM supply using its built-in VCC regulator - ideal for compact motion control in industrial automation and precision positioning systems.
For engineers reviewing the TB67S215FTAG datasheet, TB67S215FTAG pinout, TB67S215FTAG application, or TB67S215FTAG equivalent, key selection considerations include its mixed-decay PWM current control architecture, external RC-tunable chopper frequency (40–150 kHz), dual-channel RS-sense interface, and QFN36 package with exposed thermal pad requiring ground connection.
Technical Context
The TB67S215FTAG implements a two-channel H-bridge output stage with low-RDS(on) MOSFETs (0.53–0.75 Ω total per channel), driven by a step decoder that accepts CLK_IN, CW/CCW, and D_MODE1/D_MODE2 inputs to configure rotation direction and step resolution. Its internal oscillator (1.36–1.84 MHz) feeds a 1/16 divider to generate the PWM chopping frequency.
Current regulation uses analog feedback via dual RS sense pins (RS_A1/RS_A2, RS_B1/RS_B2), with threshold set independently per channel through VREF_A and VREF_B (GND–3.6 V range). Error protection includes TSD (140–170 °C), ISD (3.1–5.0 A trip), and POR (VMR = 7.0–9.0 V), all forcing output disable until reset via D_MODE standby or power cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Supply Voltage (VM) | 10–35 V typical operating range; supports up to 40 V absolute max - enables direct use with 24 V industrial rails without external regulators. |
| Output Current Capability | 2.0 A continuous per phase (typical); 2.5 A absolute max - requires thermal design to sustain >1.5 A in QFN36 package. |
| PWM Chopping Frequency | 40–150 kHz adjustable via OSCM pin (RC network) - higher frequencies reduce audible noise and improve current regulation stability. |
| Step Resolution Modes | Full, half, and quarter step via D_MODE1/D_MODE2 logic - provides 200, 400, or 800 steps/rev for enhanced positional accuracy. |
| Current Sense Interface | Dual independent RS pins per channel (RS_A1/RS_A2, RS_B1/RS_B2) - allows Kelvin sensing to reject PCB trace resistance errors. |
| Protection Functions | Thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on reset (POR) - each forces output disable until recovery condition met. |
| VREF Input Range | GND to 3.6 V with 1/5.0 gain - sets peak current as IOUT = VREF/5 ÷ RRS, enabling precise current calibration (e.g., 1.8 A with 3 V VREF and 0.33 Ω sense resistor). |
Pinout & Package
Package: P-WQFN36-0606-0.50-002 - 6 mm × 6 mm, 0.5 mm pitch, 36-pin quad flat no-lead with exposed thermal pad (must be soldered to GND plane).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK_IN (Pin 1) | Step clock input | Rising-edge-triggered timing source - each edge advances motor one electrical step; max 100 kHz input rate. |
| ENABLE (Pin 2) | Output stage enable | Active-high control - 'H' enables H-bridges; 'L' places outputs in high-impedance state for power-off or coasting. |
| CW/CCW (Pin 33) | Rotation direction select | Logic level determines motor spin direction - 'H' = clockwise, 'L' = counterclockwise; latched on CLK rising edge. |
| RS_A1/RS_A2 (Pins 6,7) | Phase A current sense | Differential sense inputs - shorted externally to measure voltage across A-phase sense resistor; used for PWM current feedback. |
| OUT_A1/OUT_A2 (Pins 8,9) | Phase A (+) outputs | High-side driver outputs - connect to motor A winding terminals; paired with OUT_A1−/OUT_A2− for full H-bridge drive. |
| OUT_A1−/OUT_A2− (Pins 11,12) | Phase A (−) outputs | Low-side driver outputs - complete A-phase H-bridge; must be routed with matched impedance to minimize shoot-through risk. |
| VREF_A/VREF_B (Pins 31,30) | Current threshold reference | Analog voltage inputs setting peak current per channel - VREF_A controls Phase A, VREF_B controls Phase B independently. |
| OSCM (Pin 32) | Oscillator frequency set | RC network connection point - sets internal oscillator frequency (1.36–1.84 MHz), which determines final chopper frequency (fchop = fOSC/16). |
| GND (Pins 4,10,13,15,18,29) | Ground reference | Multiple dedicated GND pins - must be shorted together and connected to large copper pour under exposed pad for thermal and noise performance. |
| VM (Pin 23) | Motor power supply | Main high-current input - supplies both H-bridge outputs and internal regulator; requires low-ESR bulk capacitance near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-decay PWM control | 37.5% fixed slow-decay portion per chopper cycle - balances torque ripple reduction and current regulation accuracy across speed ranges. |
| Single-supply operation | Built-in VCC regulator powered from VM - eliminates need for separate logic supply; VCC pin (25) monitors regulated 5 V output. |
| Electric angle monitor (MO_OUT) | Open-drain output reflecting real-time rotor position - provides diagnostic feedback for closed-loop verification or stall detection. |
| Independent channel current tuning | VREF_A and VREF_B allow asymmetric current settings - supports microstepping optimization or torque balancing between phases. |
| Robust fault protection | Three-tier safety: ISD responds to overcurrent at RS pins, TSD triggers at junction temp ≥140 °C, POR holds outputs off until VM stabilizes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar stepping motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN820 | Integrated current sense amplifier (no external RS resistors required); lower max VM (45 V vs. 40 V); SPI interface instead of parallel D_MODE/CLK_IN. | Requires MCU with SPI support; eliminates sense resistor layout but adds firmware complexity for mode configuration. | Choose STSPIN820 when system-level integration (SPI control, diagnostics) outweighs simplicity of TB67S215FTAG's hardware-configured step modes. |
| MP6500 | Higher continuous current rating (2.5 A vs. 2.0 A typ.); integrated 5 V LDO (not VCC regulator); no MO_OUT diagnostic pin. | Lacks electric angle monitoring; requires external 5 V rail or separate regulator; simpler feature set focused on cost-sensitive motion control. | Choose MP6500 when MO_OUT feedback is unnecessary and higher sustained current is critical in thermally optimized layouts. |
Compared with STSPIN820 and MP6500, the TB67S215FTAG offers unique hardware-based step resolution selection, real-time MO_OUT rotor position feedback, and single-VM operation with integrated VCC regulation - making it optimal for deterministic, low-firmware-overhead stepper systems where diagnostics and layout simplicity are prioritized.

FAQ
What is the maximum continuous output current supported by the TB67S215FTAG?
The TB67S215FTAG supports 2.0 A continuous output current per phase under typical operating conditions (Ta = 25 °C, VM = 24 V). While its absolute maximum rating is 2.5 A, sustained operation above 2.0 A requires careful thermal design - including proper PCB copper area, ground pad soldering, and ambient temperature control - to prevent triggering thermal shutdown. The TB67S215FTAG datasheet explicitly recommends limiting current to ≤80 % of absolute max (≈2.0 A) for reliable long-term use.
How does the TB67S215FTAG achieve microstepping without an external controller?
The TB67S215FTAG implements hardware-based microstepping using its internal step decoder and D_MODE1/D_MODE2 pins. These logic inputs directly configure full-step (L/L), half-step (L/H), or quarter-step (H/H) operation - no firmware or external sequencing logic is needed. The IC internally generates the required current waveforms using PWM current feedback and mixed-decay control, making the TB67S215FTAG a self-contained solution for precise open-loop positioning.
Can the TB67S215FTAG operate from a single 24 V supply, and how is logic power derived?
Yes, the TB67S215FTAG can operate from a single 24 V VM supply thanks to its integrated VCC regulator. This regulator derives a stable ~5 V internal supply from VM and outputs it on the VCC pin (Pin 25), which powers the logic circuitry and can also supply external components like optocouplers or level shifters. No separate logic rail is required - simplifying power architecture and reducing BOM count in compact designs using the TB67S215FTAG.
What is the function of the MO_OUT pin on the TB67S215FTAG, and how is it used?
The MO_OUT pin on the TB67S215FTAG is an open-drain electric angle monitor output that reflects real-time rotor position relative to the commanded step sequence. It pulses low during each electrical step transition and remains high otherwise - providing observable feedback for stall detection, synchronization verification, or closed-loop correction. To use it, connect a pull-up resistor (e.g., 10 kΩ to 5 V) and monitor the signal with an MCU GPIO or oscilloscope while operating the TB67S215FTAG.
How is the PWM chopping frequency set on the TB67S215FTAG, and what is its operational range?
The PWM chopping frequency on the TB67S215FTAG is set via the OSCM pin (Pin 32) using an external RC network. The internal oscillator frequency (1.36–1.84 MHz) is divided by 16 to yield the final chopper frequency, resulting in a tunable range of 40–150 kHz. For example, using R = 3.6 kΩ and C = 270 pF yields ~100 kHz - allowing engineers to optimize for torque smoothness, EMI, or audible noise suppression based on their specific motor and application requirements with the TB67S215FTAG.
