Product details
Overview
TB62215AFNG,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/3.0 A rating, integrated thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR) - deployed in industrial automation motion control systems requiring precise open-loop positioning.
For engineers reviewing the TB62215AFNG,C8,EL datasheet, TB62215AFNG,C8,EL pinout, TB62215AFNG,C8,EL application, or TB62215AFNG,C8,EL equivalent, key selection considerations include its HTSSOP48 package thermal performance, 0.6 Ω (typ.) high-side + low-side MOSFET on-resistance, 10–38 V VM operating range, 100 kHz chopper frequency, and built-in step resolution decoding via DMODE1/DMODE2 pins.
Technical Context
The TB62215AFNG,C8,EL integrates a clock-input decoder, PWM chopper controller, dual H-bridge predriver, and current-sense comparator circuitry to deliver constant-current drive for two-phase bipolar stepper motors. Its BiCD process enables 40 V breakdown voltage and 3.0 A peak output current capability.
It features programmable chopping frequency via external OSCM resistor/capacitor, selectable step resolution (full/half/quarter) through DMODE1/DMODE2 logic inputs, and real-time electric angle monitoring via MO pin output. Built-in protection includes thermal shutdown at 150 °C (typ.), over-current detection at 4.0 A (typ.), and power-on reset circuitry.
Key Specifications

|---|---|
| Motor supply voltage (VM) | 10–38 V operating range; supports 24 V nominal industrial rails with 40 V absolute max rating. |
| Peak output current | 3.0 A (absolute max); derated to ≤2.1 A typical under thermal constraints per datasheet Note 1. |
| Output on-resistance | 0.6 Ω (typ.) total (high + low side); reduces conduction loss and heat generation at rated current. |
| Chopper frequency | 100 kHz (typ.); set by external OSCM components; balances current ripple vs. switching loss. |

| 10 (RESET) | Angle reset input | Low resets MO output and electrical angle to initial state (45°); synchronizes multi-device systems. |
| 11, 20, 24, 29, 46 (GND) | Ground terminals | Multiple dedicated GND pins including exposed pad; must be connected to single-point PCB ground plane for noise and thermal integrity. |
| 13–14, 22–23, 26–27, 32–33, 35–36 (RSA/RSB/OUTA+/OUTA−/OUTB+/OUTB−) | Motor interface terminals | Dual-channel H-bridge outputs with duplicated pins for current sharing; RSA/RSB sense motor phase current for PWM feedback. |
| 39 (VM) | Motor power supply | High-current input (10–38 V); routed with wide copper pour; decoupling capacitor required near pin. |
| 41 (VREFB), 48 (VREFA) | Current reference inputs | Accept 0–3.6 V analog voltage to set peak phase current via IOUT = VREF × (1/5.0) / RSENSE. |
| 42 (VCC) | Internal regulator monitor | Supplies regulated 5 V to internal logic; must be bypassed with 0.1 µF ceramic capacitor to GND. |

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 | Lower VM rating (45 V vs. 40 V), integrated current sense, no external OSCM tuning; 36-pin QFN. | Targeted at space-constrained consumer devices; lacks MO angle monitor output and discrete VREF inputs. | Choose STSPIN220TR only if board area is critical and MO feedback is unnecessary. |
| MP6500GQ-Z | Higher current rating (2.5 A continuous), fixed 1/8-step mode, no DMODE pins; 28-pin QFN. | Optimized for cost-sensitive printer/cartridge applications; lacks quarter-step and electric angle monitor. | Select MP6500GQ-Z when full/half-step suffices and thermal headroom exceeds 1.8 A RMS requirements. |
Compared with STSPIN220TR and MP6500GQ-Z, the TB62215AFNG,C8,EL uniquely supports user-configurable chopper frequency, electric angle monitoring (MO), and independent VREFA/VREFB adjustment - making it preferred for industrial motion systems requiring diagnostic visibility and fine-grained current control.

FAQ
What is the maximum continuous output current supported by the TB62215AFNG,C8,EL under standard PCB conditions?
The TB62215AFNG,C8,EL has an absolute maximum output current rating of 3.0 A, but the recommended continuous current is ≤2.1 A (70% of absolute max) under typical ambient conditions (Ta = 85°C) and standard 4-layer PCB layout with thermal vias to the exposed pad. Derating is required above 60°C ambient or with limited copper area. The TB62215AFNG,C8,EL datasheet specifies this limit in Absolute Maximum Ratings Note 1 and Operating Ranges.
How does the MO pin function in the TB62215AFNG,C8,EL, and what is its electrical behavior?
The MO pin on the TB62215AFNG,C8,EL is an open-drain electric angle monitor output that reflects the motor's electrical rotor position in real time. It outputs a logic-low signal synchronized to the step sequence, with VOH = 3.3–5.0 V (when pulled up externally) and VOL ≤ 0.5 V at 24 mA sink. Its timing aligns with full/half/quarter-step modes and is used for stall detection or motion verification. This behavior is documented in the TB62215AFNG,C8,EL Pin Explanations section and Function Explanation (Stepping Motor) page.
Can the TB62215AFNG,C8,EL operate without external current-sense resistors?
No, the TB62215AFNG,C8,EL requires external current-sense resistors (RSA and RSB) connected between the motor phase outputs and ground to implement PWM constant-current control. These resistors feed sensed voltage to the internal comparators, enabling real-time current regulation. Omitting them disables current limiting and risks device destruction due to unregulated motor current. The TB62215AFNG,C8,EL datasheet explicitly defines RSA/RSB as mandatory in the Pin Explanations and Calculation of Predefined Output Current sections.
What thermal management practices are required for reliable operation of the TB62215AFNG,C8,EL?
Reliable operation of the TB62215AFNG,C8,EL requires mounting the exposed thermal pad to a solid GND copper plane with ≥6 thermal vias (0.3 mm diameter), routing all GND pins to that plane, and maintaining VM/GND traces with ≥1 mm width. The datasheet mandates single-point grounding and warns against exceeding 120°C junction temperature. Thermal shutdown triggers at 150°C (typ.), but sustained operation above 120°C degrades reliability. These guidelines are specified in Notes, Package Dimensions, and Absolute Maximum Ratings sections of the TB62215AFNG,C8,EL documentation.
Is the TB62215AFNG,C8,EL pin-compatible with other variants in the TB62215A family, such as TB62215AFTG or TB62215AFG?
No, the TB62215AFNG,C8,EL is not pin-compatible with TB62215AFTG (QFN48) or TB62215AFG (HSOP28). Although all share identical functional blocks and logic-level pin definitions, their physical pinouts differ significantly: TB62215AFNG,C8,EL uses HTSSOP48 with rearranged pin order (e.g., OSCM at Pin 1, CW/CCW at Pin 3), while TB62215AFTG places CW/CCW at Pin 44 and TB62215AFG at Pin 1. PCB layout must be redesigned for each package. This is confirmed in the Pin Assignment and Pin Explanations pages for each variant in the TB62215AFNG,C8,EL datasheet.
