Product details

Overview

TB67S209FTG from Toshiba Electronic Devices & Storage Corporation is a BiCD monolithic two-phase bipolar stepping motor driver with integrated PWM chopper, 50 V/4.0 A rating, 0.49 Ω (typ.) total H-bridge on-resistance, and support for microstepping down to 1/32-step resolution. It serves as the core current-control interface between MCU logic signals and industrial-grade stepper motors in precision motion systems.

For engineers reviewing the TB67S209FTG datasheet, TB67S209FTG pinout, TB67S209FTG application, or TB67S209FTG equivalent, this page delivers verified functional architecture, thermal-aware current-setting equations, mixed-decay configuration logic, error-detection behavior (TSD/ISD/UVLO), and real-world layout-critical grounding guidance - all grounded in Toshiba's Rev. 2.3.A specification.

Technical Context

The TB67S209FTG implements a clock-in controlled stepping architecture with built-in oscillator (OSCM) and step-resolution decoder, enabling direct CLK-driven position advancement without external sequencer. Its BiCD process supports high-voltage VM operation (10–47 V) and peak output current up to 4.0 A, while internal VCC regulator (4.75–5.25 V) powers logic independently of motor supply.

Current regulation uses external RS sense resistors and programmable VREF (0–3.6 V) with 1/5.0 (typ.) gain to set I_OUT(max) = VREF × (1/5.0) / R_S; chopping frequency (f_chop) is derived from OSCM (0.64–2.4 MHz) via f_chop = f_OSCM/16, adjustable with external R/C components for ripple vs. thermal trade-offs.

Key Specifications

Parameter	Value and Actual Design Meaning
Motor Supply Voltage	10–47 V - Enables direct drive of 24 V and 48 V industrial stepper motors without external DC-DC conversion.
Peak Output Current	4.0 A (abs. max) - Supports NEMA 23–34 motors; derated to ≤3.0 A typical under continuous thermal conditions.
H-Bridge On-Resistance	0.49 Ω (typ., high + low side) - Reduces conduction loss and junction heating at rated current.
Step Resolution	Full, half (A/B), quarter, 1/8, 1/16, 1/32 - Configurable via DMODE0–2 pins; enables smooth motion and reduced resonance in CNC and robotics.
Chopper Frequency Range	40–150 kHz - Adjustable via OSCM pin; higher f_chop lowers current ripple but increases switching loss.
Error Protection	TSD (145–175 °C), ISD (4.1–5.7 A), UVLO - Latched shutdown with open-drain LO output for system-level fault reporting.
VREF Input Range	0–3.6 V - Sets motor phase current threshold with ±5% accuracy; compatible with DAC or potentiometer control.

Pinout & Package

P-WQFN48-0707-0.50-003 package: 7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad (must be soldered to GND plane). Requires strict PCB grounding per Toshiba layout guidelines - single-point GND termination, dedicated power-ground routing, and isolation of high-current VM/GND/OUT traces.

Pin/Terminal	Circuit Role	Design Meaning
CLK	Clock input	Edge-triggered step advance signal; max 100 kHz; defines timing resolution of motor positioning.
ENABLE	Output stage enable	Active-low control: 'L' disables H-bridges into high-impedance state, critical during VM power sequencing.
DMODE0–2	Step resolution select	3-bit binary input selecting full through 1/32-step mode; 'LLL' enters standby (OSCM disabled).
OUTA+/OUTA− OUTB+/OUTB−	H-bridge outputs	Dual full-bridge terminals driving two motor phases; each pair paralleled internally for current sharing and thermal distribution.
RSA/RSB	Current sense inputs	Low-side sense pins tied to external shunt resistors; used with VREF to set per-phase current limit.
LO	Error output	Open-drain fault indicator: pulled high externally; goes low on TSD/ISD activation for host MCU interrupt or latch.
VREF	Current reference	Analog voltage input setting peak phase current; 0–3.6 V range maps linearly to 0–100% current scale.
OSCM	Oscillator tuning	RC-set node determining chopping frequency; 270 pF + 5.1 kΩ yields ~1.12 MHz OSCM → ~70 kHz f_chop.

Key Features

Feature	Design Value
PWM constant-current drive	Eliminates torque variation across speed range by maintaining precise phase current regardless of back-EMF or load changes.
Selectable Mixed Decay	SMD0/SMD1 pins configure fast-decay ratio (12.5% to 100%), optimizing current settling time and motor noise in microstepping modes.
Built-in error detection	Independent TSD, ISD, and UVLO circuits feed into single open-drain LO pin - simplifies system-level fault monitoring without additional logic.
Integrated VCC regulator	Generates stable 5.0 V (±2.5%) from VM supply for internal logic, removing need for external LDO and reducing BOM count.
Angle monitor output (MO)	Provides real-time electrical angle feedback synchronized to CLK; supports closed-loop microstepping verification and stall detection.

FAQ

What is the maximum continuous output current supported by the TB67S209FTG under standard PCB conditions?

The TB67S209FTG supports up to 3.0 A continuous output current (per phase) under typical operating conditions (Ta = 25 °C, 4-layer PCB with θ_j-a = 25 °C/W), as specified in Table 8.1 Operation Ranges. While its absolute maximum rating is 4.0 A, sustained operation above 3.0 A requires aggressive thermal management - including optimized copper pour, forced airflow, or reduced ambient temperature - to prevent TSD activation. The actual usable current must be validated against measured junction temperature in the final layout.

How does the TB67S209FTG implement current regulation, and what components determine the set current value?

The TB67S209FTG uses external current-sense resistors (RSA/RSB) and the VREF pin to establish peak phase current via I_OUT(max) = VREF × (1/5.0) / R_S. For example, with VREF = 3.0 V and R_S = 0.51 Ω, the calculated current is 1.18 A. This equation assumes typical VREF gain of 1/5.0; gain tolerance is ±4% (1/4.8 to 1/5.2), and current accuracy is ±5% across temperature and supply variations. The TB67S209FTG continuously compares sensed voltage across RSA/RSB to the VREF-derived threshold during PWM on-time.

Can the TB67S209FTG operate without an external microcontroller, and what minimal external components are required?

Yes - the TB67S209FTG supports standalone operation using only a clock source (e.g., crystal oscillator or MCU GPIO), direction control (CW/CCW), and ENABLE/RESET signals. Required external components include: (1) VREF-setting resistor or DAC, (2) RSA/RSB current-sense resistors (typically 0.1–0.5 Ω), (3) OSCM RC network (e.g., 5.1 kΩ + 270 pF), (4) 10 kΩ pull-up on LO, and (5) proper decoupling capacitors on VM and VCC. No firmware or serial interface is needed for basic step/direction control.

What is the function of the MO (Monitor Output) pin on the TB67S209FTG, and how is it used in practice?

The MO pin outputs a square-wave signal synchronized to the motor's electrical angle, with frequency proportional to step rate and duty cycle reflecting phase current polarity. In practice, it enables real-time verification of stepping integrity - e.g., detecting missed steps or stalls by comparing MO edge count against expected CLK edges in firmware. When pulled up to 3.3 V or 5.0 V, MO delivers rail-to-rail logic levels compatible with most MCU inputs; its waveform matches the timing charts in Figures 6.1–6.7 for each resolution mode.

How does the Selectable Mixed Decay feature work on the TB67S209FTG, and why is it important for microstepping performance?

The TB67S209FTG's Selectable Mixed Decay uses SMD0/SMD1 pins to set the percentage of Fast Decay within each chopper cycle (12.5%, 37.5%, 50%, or 100%). This directly controls how quickly phase current decays after the charge period - critical for maintaining accurate current waveforms in microstepping. Too much slow decay causes current overshoot and resonance; too much fast decay increases ripple and acoustic noise. Tuning SMD0/SMD1 allows optimization for specific motor inductance and target speed, improving torque linearity and reducing vibration in 1/8–1/32 step modes.
