Product details
Overview
TB62215AFTG,C8,EL from Toshiba is a clock-in controlled bipolar stepping motor driver IC using PWM chopper current control, supporting full/half/quarter-step operation with 40 V maximum motor supply voltage and 3.0 A peak output current. It integrates thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR) protection circuits, and is designed for precision motion control in industrial automation and office equipment.
For engineers reviewing the TB62215AFTG,C8,EL datasheet, TB62215AFTG,C8,EL pinout, TB62215AFTG,C8,EL application, or TB62215AFTG,C8,EL equivalent, key selection considerations include its QFN48 package thermal performance, dual-channel current-sense architecture (RSA/RSB), OSCM-based chopper frequency tuning, and compatibility with 10–38 V motor supplies and 2–5.5 V logic interfaces.
Technical Context
The TB62215AFTG,C8,EL implements a mixed-decay PWM chopper architecture with user-configurable oscillation frequency via external R/C on the OSCM pin (1.2–2.0 MHz typical), yielding a chopper frequency of ~100 kHz. Its internal VCC regulator powers logic circuitry from VM, eliminating need for separate logic supply.
Motor phase current is regulated via two independent current-sense inputs (RSA and RSB), each paired with dedicated VREFA/VREFB reference pins to set peak current per channel. Step resolution (full/half/quarter) and direction (CW/CCW) are controlled digitally through DMODE1/DMODE2 and CW/CCW pins, while ENABLE places outputs in high-impedance state for power-saving stop mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Motor Supply Voltage | 10–38 V - Supports wide-range DC motors including 24 V industrial stepper systems. |
| Peak Output Current | 3.0 A - Absolute max rating; usable continuous current depends on PCB thermal design and ambient temperature. |
| Output ON-Resistance | 0.6 Ω (typ., high + low side) - Minimizes conduction loss and heat generation at rated current. |
| Chopper Frequency | ~100 kHz - Set by OSCM pin; balances current ripple reduction vs. internal switching loss. |
| Logic Input Thresholds | VIN(H) ≥ 2.0 V, VIN(L) ≤ 0.8 V - Compatible with standard 3.3 V and 5 V microcontroller GPIOs. |
| Protection Functions | TSD (140–170 °C), ISD (3.0–5.0 A), POR - Autonomous fault response without host intervention required. |
| Step Resolution Modes | Full / Half / Quarter - Configured via DMODE1/DMODE2; enables torque/speed/resolution trade-offs. |
Pinout & Package
Package: QFN48-P-0707-0.50 (7.0 mm × 7.0 mm, 0.5 mm pitch, exposed thermal pad). Mounting requires soldering all four corner pins and the exposed pad to PCB GND for optimal thermal dissipation and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK | Clock input | Edge-triggered step advance signal; minimum pulse width 300 ns (H), 250 ns (L). |
| ENABLE | Output stage enable | Low = high-impedance OFF state; must be held low during VM power sequencing. |
| RSA / RSB | Current sense inputs | Differential sensing of motor phase A/B current; connect to external sense resistors. |
| OUTA+/OUTA− / OUTB+/OUTB− | H-bridge outputs | Four dedicated power terminals per phase; multiple pins per function improve current handling and thermal spreading. |
| VREFA / VREFB | Current reference inputs | Analog voltage (0–3.6 V) sets peak current: IOUT = VREF / 5.0 / RSENSE. |
| OSCM | Oscillator frequency set | RC network (e.g., 270 pF + 3.6 kΩ) sets chopper clock; 1.2–2.0 MHz range. |
| VM | Motor power supply | Main high-voltage rail (10–38 V); feeds both H-bridge and internal regulator. |
| VCC | Internal regulator monitor | 5.0 V ±250 mV output; powers logic core; no external supply needed. |
Key Features
| Feature | Design Value |
|---|---|
| PWM constant-current drive | Enables precise microstepping (full/half/quarter) with stable torque across speed range. |
| Integrated protection suite | TSD, ISD, and POR prevent latch-up or destruction under overload, short-circuit, or thermal stress. |
| BiCD monolithic process | Combines high-voltage BJT and low-RDS(on) MOSFETs in single die for efficiency and integration. |
| Configurable chopper frequency | External RC on OSCM allows optimization of current ripple vs. switching loss for specific motor inductance. |

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 |
|---|---|---|---|
| STSPIN220TR | Lower max VM (45 V), lower peak current (1.6 A), integrated current regulation but no external OSCM tuning. | Better suited for compact, low-power applications; lacks quarter-step mode and dual VREF flexibility. | Choose STSPIN220TR when board space and cost are prioritized over high-current capability and fine-grained chopper control. |
| MP6500GQ-Z | Higher VM rating (46 V), 2.5 A peak, fixed 1/8-step mode only, no MO angle monitor output. | Optimized for high-speed, low-latency motion; missing electric angle feedback limits closed-loop use cases. | Choose MP6500GQ-Z for high-throughput indexing where simple step/direction interface suffices and thermal margin is adequate. |
Compared with STSPIN220TR and MP6500GQ-Z, the TB62215AFTG,C8,EL offers superior configurability (quarter-step, OSCM tuning, dual VREF), higher current drive (3.0 A), and integrated angle monitoring (MO pin), making it preferred for precision industrial motion where resolution, thermal robustness, and diagnostic visibility matter.

FAQ
What is the recommended external component configuration for the OSCM pin on the TB62215AFTG,C8,EL?
The TB62215AFTG,C8,EL OSCM pin uses an external resistor and capacitor to set chopper frequency. A typical configuration is 3.6 kΩ resistor and 270 pF capacitor, yielding ~1.6 MHz oscillator frequency and ~100 kHz chopper frequency. This balances current ripple reduction and internal switching losses. Values must be selected within the specified OSCM frequency range (1.2–2.0 MHz) to ensure stable PWM operation; deviations may cause erratic current regulation or increased thermal stress in the TB62215AFTG,C8,EL.
How does the TB62215AFTG,C8,EL handle thermal protection, and what triggers its thermal shutdown?
The TB62215AFTG,C8,EL incorporates a junction temperature-based thermal shutdown (TSD) circuit that activates when die temperature reaches 140–170 °C. Upon triggering, the device disables all output transistors and enters standby mode. Recovery requires either VM power cycle or setting DMODE1/DMODE2 to standby mode. The TSD is a safety backup-not intended for continuous operation-and proper PCB thermal design (exposed pad to GND, copper area ≥ 200 mm²) is essential to avoid activation during normal use of the TB62215AFTG,C8,EL.
Can the TB62215AFTG,C8,EL drive stepper motors with asymmetric winding resistance or inductance?
Yes, the TB62215AFTG,C8,EL supports asymmetric motor windings via independent current control per phase: VREFA sets peak current for phase A (OUTA+/OUTA−), and VREFB sets peak current for phase B (OUTB+/OUTB−). Each channel uses its own sense resistor (RSA/RSB) and reference voltage, enabling torque balancing or compensation for mismatched windings. This capability is confirmed in the TB62215AFTG,C8,EL datasheet section "Calculation of the Predefined Output Current" and makes the TB62215AFTG,C8,EL suitable for custom or legacy motor integration.
What is the function of the MO pin on the TB62215AFTG,C8,EL, and how is it used in system design?
MO (Motor Angle Monitor) is an open-drain digital output on the TB62215AFTG,C8,EL that indicates electrical angle position-low during initial angle (45°), toggling per step in full/half/quarter modes. It provides real-time feedback for closed-loop verification or stall detection without external encoder. Pull-up resistor (10–100 kΩ to VCC) is required. In system design, MO enables synchronization with host controller timing, error detection (e.g., missed steps), and dynamic resolution adjustment-all using the native TB62215AFTG,C8,EL interface without added components.
Does the TB62215AFTG,C8,EL require an external logic supply, or is VCC internally generated?
The TB62215AFTG,C8,EL includes an internal VCC regulator powered from the VM rail, generating a stable 5.0 V ±250 mV supply for internal logic. No external logic supply is required-the VCC pin is an output, not an input. This simplifies system design by eliminating a separate 5 V rail. However, the VCC pin must be decoupled with a 1 µF ceramic capacitor to GND near the device, as specified in the TB62215AFTG,C8,EL application guidelines, to maintain noise immunity and regulator stability.
