Product details
Overview
TB62213AFTG from Toshiba is a two-phase bipolar stepping motor driver IC using PWM chopper control, fabricated in BiCD silicon monolithic process. It delivers 40 V/3.0 A output capability, supports Full/Half/¼-step excitation modes, and integrates on-chip VCC regulator enabling single VM supply operation - used in precision motion control for industrial automation actuators.
For engineers reviewing the TB62213AFTG datasheet, TB62213AFTG pinout, TB62213AFTG application, or TB62213AFTG equivalent, this page provides verified technical context, real-world stepping motor drive specifications, QFN48 package layout guidance, thermal and overcurrent protection behavior, and validated alternative options for motor control system design.
Technical Context
The TB62213AFTG implements mixed-decay PWM current control with dual H-bridge outputs, driven by a programmable chopper oscillator (fOSCM = 1.2–2.0 MHz) that sets fchop = fOSCM/16 (40–150 kHz). Its step decoder accepts IN_A1/IN_A2/PHASE_A and IN_B1/IN_B2/PHASE_B logic inputs to generate phase currents with 2-bit D/A torque control.
Current regulation uses external sense resistors (RS_A, RS_B) and VREF_A/VREF_B reference pins, where IOUT = VREF/5/RRS. Protection includes thermal shutdown (TSD, 140–170°C), overcurrent shutdown (ISD, 3.0–5.0 A per phase), and power-on reset (POR) for VM and VCC - all disabling outputs until STANDBY toggled or rebooted.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Rating | 40 V - supports stepper motors with up to 38 V nominal supply (VM = 10–38 V operating range) |
| Continuous Output Current | 2.4 A per phase (typ.) - enables driving NEMA 17–23 size bipolar steppers at full torque without forced cooling |
| Chopper Frequency | 100 kHz (typ.) - balances low audible noise and efficient switching loss; adjustable via OSCM external RC network |
| On-Resistance (HS+LS) | 0.6 Ω (typ.) - reduces conduction loss and thermal load in QFN48 package under 2.4 A load |
| VREF Decay Rate | 1/5.0 (typ.) - defines fixed gain between VREF voltage and output current setpoint (IOUT = VREF/5/RRS) |
| Logic Input Threshold | VIN(H) ≥ 2.0 V, VIN(L) ≤ 0.8 V - compatible with 3.3 V and 5 V microcontroller GPIO without level shifting |
| Thermal Shutdown Threshold | 150 °C (typ.) - junction temperature limit with hysteresis; disables outputs until STANDBY cycle or power reset |
Pinout & Package
Package: QFN48-P-0707-0.50 (7.0 mm × 7.0 mm, 0.50 mm pitch, exposed thermal pad). Thermal pad must be soldered to solid ground plane for heat dissipation; total weight is 0.14 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT_A+, OUT_A− (Pins 10,11,16,17) |
Phase A H-bridge output terminals | Dual parallel pins per terminal reduce trace inductance and current density; connect directly to motor coil A |
| OUT_B+, OUT_B− (Pins 20,21,26,27) |
Phase B H-bridge output terminals | Dual parallel pins per terminal ensure balanced current sharing and minimize thermal stress during 2.4 A operation |
| RS_A, RS_B (Pins 7,8,29,30) |
Current sense resistor connections | Paired pins per channel require short, low-inductance routing to sense resistors (e.g., 0.51 Ω) for accurate PWM regulation |
| VREF_A, VREF_B (Pins 42,41) |
Reference voltage inputs for current setting | Set peak phase current via external voltage (0–3.6 V); each controls one motor phase independently |
| OSCM (Pin 43) |
Oscillator frequency programming node | Connects to external R1 (3.6 kΩ) and C (270 pF) to fix fOSCM = 1.6 MHz → fchop = 100 kHz |
| STANDBY (Pin 4) |
Global enable/disable control | Pull low to disable oscillator and outputs; eliminates quiescent current (IM1 ≤ 3.0 mA) during idle |
| VM (Pin 32) |
Main motor power supply input | Accepts 10–38 V DC; requires ≥100 µF bulk capacitance and 0.1 µF ceramic bypass near pin |
| GND (Pins 5,15,18,19,22,40) |
Ground return paths | Six dedicated GND pins - must be tied to single-point ground plane beneath thermal pad to minimize noise and voltage drop |
Key Features
| Feature | Design Value |
|---|---|
| BiCD monolithic integration | Enables 40 V/3.0 A rating with <0.8 Ω total H-bridge RDS(on) in compact QFN48, eliminating discrete MOSFET drivers |
| Three-step resolution support | Hardware-selectable Full/Half/¼-step via IN/PHASE logic sequences - no firmware interpolation needed for microstepping |
| Single-supply operation | VCC regulator powered from VM eliminates need for separate 5 V rail; VCC pin (34) monitors internal regulator status |
| Programmable chopping frequency | fchop adjusted from 40–150 kHz via OSCM RC network - allows optimization for EMI, torque ripple, and efficiency |
| Dual independent current control | VREF_A and VREF_B allow asymmetric current tuning per phase - compensates for motor winding mismatch or load imbalance |

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 |
|---|---|---|---|
| TB62208AFG | Lower voltage rating (36 V max), 2.5 A max output, same QFN48 package and pinout | Suitable for 24 V systems with lower torque requirements; lacks VREF_B independent control | Select when VM ≤ 24 V and phase current ≤ 2.0 A; verify OSCM component values match |
| STK672-410 | Higher integration (integrated current sense resistors), 40 V/2.8 A, HTSSOP28 package | Requires no external RS resistors but offers only single VREF; smaller PCB footprint but higher thermal resistance | Prefer for cost-sensitive, space-constrained designs where 2.8 A suffices and layout simplicity outweighs thermal performance |
Compared with TB62208AFG, the TB62213AFTG provides higher VM tolerance (40 V vs. 36 V) and independent VREF control per phase - critical for asymmetric load compensation. Versus STK672-410, TB62213AFTG's QFN48 offers superior thermal dissipation (1.3 W vs. ~0.9 W) and flexible external current sensing, supporting higher continuous current in thermally demanding environments.

FAQ
What is the maximum continuous output current per phase for the TB62213AFTG?
The TB62213AFTG delivers 2.4 A per phase continuously under typical conditions (Ta = 25°C, VM = 24 V). This value is derated above 25°C ambient at 10.4 mW/°C. The absolute maximum rating is 3.0 A, but sustained operation at that level requires aggressive thermal management via the QFN48 exposed pad and multilayer PCB copper pour.
How does the TB62213AFTG achieve single-supply operation without an external VCC regulator?
The TB62213AFTG integrates an on-chip VCC regulator powered directly from the VM supply. When VM is applied within 10–38 V, the internal regulator generates stable 5.0 V (±2.5%) for logic and gate drive circuits - confirmed by VCC pin (34) monitoring. This eliminates need for external 5 V rails in systems like portable medical devices or battery-powered CNC tools.
Can the TB62213AFTG drive unipolar stepper motors?
No, the TB62213AFTG is designed exclusively for two-phase bipolar stepper motors. Its dual H-bridge architecture (OUT_A+/−, OUT_B+/−) requires center-tap–free windings and cannot interface with unipolar 5- or 6-wire motors. Attempting unipolar use will result in incorrect phase sequencing and potential output stage damage.
What happens when the TB62213AFTG enters thermal shutdown (TSD)?
When junction temperature exceeds 150°C (typ.), the TB62213AFTG disables all outputs while retaining their last state. Recovery requires toggling the STANDBY pin (low→high) or performing a full power cycle. During TSD, the device remains powered but ceases motor current delivery - preventing coil overheating and irreversible magnet demagnetization in the connected stepper.
How is the chopper frequency set on the TB62213AFTG, and what is its operational range?
The chopper frequency (fchop) is derived from the OSCM oscillator frequency (fOSCM) via fchop = fOSCM/16. fOSCM is set externally using a resistor (R1 = 3.6 kΩ) and capacitor (C = 270 pF) on pin OSCM (43), yielding fOSCM = 1.6 MHz → fchop = 100 kHz (typ.). The configurable range spans 40–150 kHz, allowing EMI reduction or efficiency tuning without changing firmware.
