Product details
Overview
TB62262FTAG from Toshiba is a CLK-in controlled bipolar stepping motor driver IC using PWM chopper current regulation, fabricated in BiCD process with 40 V/1.5 A absolute max ratings, supporting full/half/quarter-step resolution and integrated thermal (TSD) and overcurrent (ISD) protection for industrial motion control applications.
For engineers reviewing the TB62262FTAG datasheet, TB62262FTAG pinout, TB62262FTAG application, or TB62262FTAG equivalent, key selection criteria include its QFN36 package with dual current-sense pins per phase, programmable chopping frequency via OSCM pin, 0.8 Ω typical high-side + low-side ON-resistance, and dedicated MO angle monitor output for closed-loop feedback integration.
Technical Context
The TB62262FTAG integrates a CLK decoder, step-resolution selector (DMODE1/DMODE2), and dual-channel PWM current control logic with independent VREFA/VREFB reference inputs. Its internal oscillator (OSCM) sets chopper frequency (40–150 kHz), while RSA/RSB sense resistors enable precise peak current regulation per phase.
It implements mixed-decay mode switching across CHARGE/SLOW/FAST states to maintain constant motor current under varying back-EMF conditions. Error detection outputs (TSD/ISD) drive external fault handling, and the built-in VCC regulator powers internal logic from VM supply.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bipolar stepper motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STSPIN220TR | 8 V–45 V VM range; 1.3 A max; integrated current sense; no MO pin; 3×3 mm QFN24 | Lacks angle monitor output and dual VREF inputs; simpler configuration but less diagnostic capability | Preferred for cost-sensitive, space-constrained designs where MO feedback is unnecessary. |
| DRV8825PWPR | 8.2 V–45 V VM; 2.2 A max; microstep up to 1/32; no integrated TSD/ISD; 28-pin HTSSOP | Higher current and finer microstepping, but requires external thermal/current protection circuitry | Chosen when higher torque or ultra-fine positioning is required and board area permits larger package. |
Compared with STSPIN220TR and DRV8825PWPR, the TB62262FTAG uniquely combines integrated angle monitoring (MO), dual independent VREF inputs for asymmetric phase tuning, and hardware-latched TSD/ISD protection - making it optimal for safety-critical or closed-loop-enhanced motion systems where diagnostics and reliability outweigh raw current rating.

FAQ
What is the maximum continuous output current supported by the TB62262FTAG?
The TB62262FTAG supports a typical continuous output current of 0.8–1.2 A per phase under standard operating conditions (Ta = 25°C, VM = 24 V, proper PCB heatsinking). Absolute maximum rating is 1.5 A, but sustained operation above 1.2 A requires aggressive thermal design due to power dissipation limits in the P-WQFN36 package. The actual usable current depends on ambient temperature, copper area, and airflow - refer to the PD-Ta derating curve in the datasheet for precise thermal modeling of TB62262FTAG.
How does the MO (Monitor Output) pin function in the TB62262FTAG?
The MO pin on the TB62262FTAG is an open-drain electric angle monitor output that reflects real-time rotor electrical angle during stepping. It toggles synchronously with current polarity changes in the motor windings and can be pulled up externally to generate a square wave whose duty cycle corresponds to step position. This signal enables stall detection, basic position tracking, or synchronization with external vision or timing systems - a feature not found in most competing stepper drivers. For TB62262FTAG, MO behavior is directly tied to DMODE-selected resolution and CW/CCW state.
Can the TB62262FTAG drive unipolar stepper motors?
No, the TB62262FTAG is designed exclusively for two-phase bipolar stepper motors. Its H-bridge architecture (OUTA+/OUTA− and OUTB+/OUTB−) requires center-tap–free windings and bidirectional current control. Unipolar motors have center-tapped coils and rely on single-direction current per half-winding, which is incompatible with TB62262FTAG's output structure and current-sensing scheme (RSA/RSB). Attempting to connect a unipolar motor may result in improper excitation, excessive heating, or device malfunction.
What external components are required for basic operation of the TB62262FTAG?
For basic operation, the TB62262FTAG requires: (1) two identical current-sense resistors (e.g., 0.51 Ω) connected between RSA/RSB and GND; (2) VREFA/VREFB set to desired reference voltage (0–3.6 V) via DAC or resistor divider; (3) OSCM network (e.g., 270 pF capacitor + 3.6 kΩ resistor) to set chopper frequency; (4) 100 µF bulk capacitor on VM and 0.1 µF ceramic capacitors near VCC and GND pins. The exposed thermal pad must be soldered to a large GND copper area. These values are validated in the TB62262FTAG example application circuit.
Does the TB62262FTAG support automatic current decay mode selection?
Yes, the TB62262FTAG implements mixed-decay mode automatically - dynamically blending slow and fast decay based on real-time current error to minimize ripple and acoustic noise. Unlike fixed-decay drivers, it does not require external configuration for decay behavior. The internal control logic monitors current through RSA/RSB and adjusts U1/U2/L1/L2 transistor states across CHARGE → SLOW → FAST phases within each chopper cycle. This adaptive decay is inherent to TB62262FTAG's architecture and operates across all step resolutions without user intervention.
