Product details

Overview

TB62215AHQ from Toshiba is a clock-in controlled, two-phase bipolar stepping motor driver IC fabricated in BiCD process, delivering 40 V/3.0 A output capability with PWM chopper current control, full/half/quarter-step resolution, and integrated thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR) protection - used in precision motion control for industrial automation actuators, optical positioning stages, and medical infusion pump drives.

For engineers reviewing the TB62215AHQ datasheet, TB62215AHQ pinout, TB62215AHQ application, or TB62215AHQ equivalent, this page delivers verified technical context, HZIP25 package-specific pin functions, real-world step resolution behavior, current-sense resistor design implications, and validated alternative options for motor driver selection in thermally demanding embedded motion systems.

Technical Context

The TB62215AHQ implements a dedicated clock-input decoder with built-in oscillator (OSCM) for chopping frequency tuning via external RC network (f_OSCM = 0.64–2.4 MHz, f_chop = f_OSCM/16), enabling precise current regulation across full/half/quarter-step modes. Its dual-channel predriver supports mixed-decay mode operation with charge/slow/fast timing states.

It integrates a 5.0 V internal VCC regulator, low on-resistance output stage (R_on(H+L) = 0.6 Ω typ.), and analog current sensing via RSA/RSB pins with VREF input (0–3.6 V) to set peak motor current (I_OUT(max) = VREF × gain / R_S, gain = 1/5.0 typ.). Thermal shutdown triggers at T_j = 140–170 °C; over-current detection activates at I_OUT ≥ 3.0–5.0 A.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage Rating	40 V max - supports 24 V nominal motor supplies with margin for back-EMF spikes in inductive loads.
Continuous Output Current	3.0 A max - absolute rating; derated to ≤2.1 A typical under 85°C ambient with HZIP25 thermal design.
Step Resolution Modes	Full / Half / Quarter - selected via DMODE1/DMODE2 logic inputs; quarter-step enables 4× microstepping granularity.
Chopping Frequency Range	40–150 kHz - adjustable via OSCM pin; 100 kHz typical (f_OSCM = 1.6 MHz) balances ripple reduction and gate loss.
Current Sense Accuracy	±5% - ensures repeatable torque output across temperature and unit-to-unit variation when using matched RS resistors.
Thermal Shutdown Threshold	140–170 °C - junction-based protection with hysteresis; recovery requires VM power cycle or DMODE standby entry.
Logic Input Compatibility	VIH = 2.0–5.5 V, VIL = 0–0.8 V - compatible with 3.3 V and 5 V microcontrollers without level shifting.

Pinout & Package

HZIP25-P-1.00F package: 25-pin single-ended through-hole mount with integral heat sink tab (FIN), 7.6 g typical weight, designed for high-power dissipation (P_D = 3.2 W at T_a = 25°C). Mount FIN directly to PCB ground plane for optimal thermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1, 3–4, 8, 11, 13, 15, 23	GND	Seven dedicated ground terminals - must be connected to a common low-impedance ground plane; critical for noise immunity and thermal conduction.
10, 12, 14, 16	OUTA+, OUTA−, OUTB−, OUTB+	Four motor phase outputs - drive two-phase bipolar stepper windings; require symmetric trace routing and Kelvin sense layout for current accuracy.
9, 17	RSA, RSB	Current sense inputs - connect to low-side sense resistors (typ. 0.1–1 Ω); sensitive analog nodes requiring guard traces and local decoupling.
5, 6, 7, 19, 22, 24, 25	CLK, ENABLE, RESET, VM, VCC, VREF, OSCM	Digital control, power, and configuration pins - CLK accepts up to 100 kHz; VM supports 10–38 V; VREF sets peak current; OSCM sets chopper frequency.
18, 20–21	NC	No-connect pins - must remain unconnected; no routing or copper under these pads per Toshiba layout guidance.

Key Features

Feature	Design Value
PWM constant-current drive	Enables stable torque across speed range via real-time current regulation; eliminates current droop in inductive windings.
Built-in mixed-decay mode	Automatically blends slow/fast decay during current recirculation - reduces audible noise and improves step accuracy at low speeds.
Integrated error protection	TSD, ISD, and POR circuits autonomously disable outputs on fault - prevents latch-up and secondary damage during overload or thermal stress.
On-resistance <0.6 Ω (H+L)	Minimizes conduction loss and self-heating - critical for maintaining 3 A capability in HZIP25's 3.2 W thermal envelope.
External OSCM tuning	Allows chopper frequency optimization (40–150 kHz) for specific motor inductance and EMI requirements without changing IC.

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
STK672-440	Higher voltage rating (50 V), but no integrated OSCM tuning or MO angle monitor; uses external oscillator.	Lacks quarter-step resolution and electric angle feedback - suitable only for full/half-step systems without stall detection.	Choose STK672-440 only if 50 V motor supply is required and MO feedback is unnecessary; verify external oscillator stability.
DRV8825	Lower voltage (45 V) and current (2.2 A) ratings; microstepping up to 1/32-step; no integrated TSD/ISD - relies on external thermal management.	Supports finer microstepping but lacks autonomous fault protection - requires host MCU supervision for overtemperature/overcurrent.	Prefer DRV8825 for ultra-fine positioning where thermal headroom is ample and firmware can manage fault responses.

Compared with STK672-440 and DRV8825, the TB62215AHQ uniquely combines HZIP25's 3.2 W thermal capacity, integrated quarter-step + MO feedback, and autonomous TSD/ISD - making it optimal for industrial motion systems where reliability under sustained load is non-negotiable.

FAQ

What is the maximum continuous motor current supported by the TB62215AHQ in its HZIP25 package?

The TB62215AHQ has an absolute maximum output current rating of 3.0 A, but its practical continuous current is thermally limited. In the HZIP25 package (P_D = 3.2 W at T_a = 25°C), sustained operation above ~2.1 A requires aggressive heatsinking and airflow. Derating to 1.8 A is recommended for reliable 85°C ambient operation without forced cooling - confirmed by Toshiba's Operation Ranges table and thermal resistance modeling.

How does the OSCM pin configure chopper frequency in the TB62215AHQ?

The OSCM pin sets the internal oscillator frequency (f_OSCM) via an external RC network: f_OSCM ≈ 1/[0.56 × C × (R + 500)]. With typical values C = 270 pF and R = 3.6 kΩ, f_OSCM = 1.6 MHz, yielding a chopper frequency f_chop = f_OSCM/16 = 100 kHz. This direct RC tuning allows designers to optimize trade-offs between current ripple (lower f_chop) and switching loss (higher f_chop) for their specific motor inductance.

Can the TB62215AHQ operate in quarter-step mode without external microcontroller intervention?

Yes - the TB62215AHQ implements native quarter-step resolution using only its DMODE1 and DMODE2 logic inputs. When both pins are driven high (H/H), the internal step resolution selector configures the driver for quarter-step operation, generating four electrical steps per full mechanical step. No external sequencing logic or firmware is needed; the CLK input advances position, and CW/CCW selects direction - all fully hardware-managed.

What is the function of the MO (Monitor Output) pin on the TB62215AHQ?

The MO pin on the TB62215AHQ outputs a digital signal synchronized to the motor's electrical angle - high during positive current half-cycles and low during negative ones. It provides real-time rotor position feedback without encoders, enabling stall detection (loss of MO toggling), phase alignment verification, and closed-loop correction in host systems. Its VOH/VOL specs (3.3–5.0 V / 0–0.5 V) ensure compatibility with standard logic interfaces.

Does the TB62215AHQ require external current-sense resistors, and how are they connected?

Yes - the TB62215AHQ requires two external low-value sense resistors (one per phase) connected between the RSA/RSB pins and GND. These resistors (typically 0.1–1 Ω) convert motor current into a voltage sensed by the IC's internal comparators. The peak current is calculated as I_OUT(max) = VREF × (1/5.0) / R_S; for example, with VREF = 3.0 V and R_S = 0.51 Ω, I_OUT = 1.18 A. Kelvin connections and ground-plane isolation are mandatory for accuracy.
