Product details

Overview

TB62214AFNG,C8,EL from Toshiba is a BiCD monolithic two-phase bipolar stepping motor driver IC with PWM chopper control, rated for 40 V/2.0 A absolute maximum output, supporting clock-input excitation and mixed-decay constant-current drive. It integrates thermal shutdown (TSD), overcurrent shutdown (ISD), and power-on reset (POR) protection, and operates with a single VM supply via on-chip voltage regulation - used in precision motion control systems such as industrial automation actuators and CNC positioning stages.

For engineers reviewing the TB62214AFNG,C8,EL datasheet, TB62214AFNG,C8,EL pinout, TB62214AFNG,C8,EL application, or TB62214AFNG,C8,EL equivalent, key selection considerations include its HTSSOP48 package, 100 kHz max clock input frequency, 40 V/2.0 A output capability, mixed-decay PWM current control architecture, and excitation mode flexibility (two-phase, 1-2-phase, W1-2-phase).

Technical Context

The TB62214AFNG,C8,EL implements a dual H-bridge output stage using DMOS FETs fabricated in Toshiba's BiCD process, enabling high-voltage (40 V) and high-current (2.0 A per phase) operation. Its internal CR oscillator generates chopper frequencies from 40–150 kHz, synchronized to an external OSCM capacitor-resistor network.

Current regulation uses real-time RS-pin sensing with VREF-based threshold tuning (I_OUT = V_REF/5 ÷ R_S), and decay mode sequencing is fixed at 37.5% fast-decay / 62.5% slow-decay within each PWM cycle. Protection logic includes independent ISD per phase (trip threshold ≥2.0 A), TSD at 140–170°C, and POR monitoring of both VM and VCC rails.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage Rating	40 V - supports stepper motors with up to 38 V operating supply (VM range: 10–38 V)
Continuous Output Current	1.4 A per phase (typ.) - derated from 2.0 A absolute max due to thermal limits at Ta ≤85°C
Chopper Frequency	100 kHz (typ.) - enables precise current ripple control and low audible noise in motor windings
Max Clock Input Frequency	100 kHz - determines maximum step rate; timing-critical for microstepping coordination
VREF Decay Rate	1/5.0 (typ.) - sets current scaling factor between reference voltage and sense resistor (I_OUT = V_REF/5 ÷ R_S)
TSD Threshold	150°C (typ.) - junction temperature at which all outputs disable; recovery requires D_MODE pin reset or reboot
ISD Trip Threshold	3.0 A (typ.) - per-phase overcurrent detection level; includes 4-cycle masking to suppress switching noise false triggers

Pinout & Package

Package: HTSSOP48-P-300-0.50 - thermally enhanced 48-pin thin shrink small outline package with 0.50 mm pitch, exposed thermal pad (pin 25/29/20/24 GND), optimized for motor driver heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
OUT_A1 / OUT_A2 / OUT_B1 / OUT_B2	H-bridge output terminals	Drive A/B phase coils in bipolar configuration; OUT_A1/OUT_A2 form one full bridge, same for B-phase
RS_A1 / RS_A2 / RS_B1 / RS_B2	Current-sense return paths	Connect to low-side shunt resistors; voltage across RS pins (±1.5 V max) feeds internal current comparator
VREF_A / VREF_B	Reference voltage inputs	Set peak current per phase via I_OUT = V_REF/5 ÷ R_S; independent tuning for A/B phases
CLK / ENABLE / RESET / CW/CCW / D_MODE1 / D_MODE2	Digital control inputs	Enable step-by-step motion (CLK), direction (CW/CCW), excitation mode (D_MODEx), and safety reset (RESET)
MO_OUT	Monitor output	Open-drain electric angle indicator; pulses once per full electrical cycle - used for closed-loop verification
VM / VCC / GND (multiple)	Power distribution	VM supplies motor power (40 V max); VCC powers logic (5 V regulated); dedicated GND pins separate logic/motor return paths

Key Features

Feature	Design Value
Mixed-decay PWM current control	Fixed 37.5% fast-decay / 62.5% slow-decay ratio per chopper cycle - balances torque stability and power loss
Three excitation modes	Configurable via D_MODE1/D_MODE2 pins: two-phase (full-step), 1-2-phase (half-step), W1-2-phase (wave drive) - enables resolution and torque trade-offs
Integrated protection suite	Per-phase ISD, global TSD, and dual-rail POR - eliminates need for external fault-handling circuitry in basic implementations
Single-supply operation	On-chip VCC regulator powered from VM - reduces system BOM by removing separate 5 V rail for logic
BiCD DMOS output stage	1.0 Ω typical R_DS(on) (sum of upper + lower FETs) - minimizes conduction loss at 1.4 A continuous per phase

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 voltage rating (45 V vs. 40 V), integrated current sense amplifier, no MO_OUT monitor pin	Lacks electric angle feedback; requires external current sensing for closed-loop verification	Preferred when board space is constrained and MO_OUT functionality is not required
MP6500GQ-Z	Higher chopper frequency (up to 500 kHz), microstepping support, different pinout and register interface	Requires SPI configuration; not compatible with simple clock-input step control	Selected when sub-step resolution and programmable decay modes are needed over direct clock-driven simplicity

Compared with STSPIN220TR and MP6500GQ-Z, the TB62214AFNG,C8,EL offers native clock-input step control, electric angle monitoring (MO_OUT), and three hardware-selectable excitation modes - making it optimal for deterministic, low-software-overhead motion systems where timing transparency and fault visibility are prioritized over microstepping granularity.

FAQ

What is the maximum continuous output current per phase for the TB62214AFNG,C8,EL under standard operating conditions?

The TB62214AFNG,C8,EL delivers 1.4 A per phase continuously under typical conditions (Ta = 25°C, VM = 24 V, two-phase excitation). This value is thermally derated from the 2.0 A absolute maximum rating to ensure junction temperature remains below 120°C. At 85°C ambient, sustained 1.4 A operation requires adequate PCB copper area and thermal vias beneath the HTSSOP48 exposed pad - confirmed in Toshiba's thermal characterization data for TB62214AFNG,C8,EL.

How does the MO_OUT pin function in the TB62214AFNG,C8,EL, and what is its electrical interface?

The MO_OUT pin on the TB62214AFNG,C8,EL is an open-drain electric angle monitor that pulses low once per full electrical cycle (360°) of motor rotation. It operates with a 3.3–5.5 V pull-up and sinks up to 30 mA. In two-phase excitation, MO_OUT toggles every four CLK edges; in 1-2-phase, it toggles every eight. This signal enables encoderless position tracking and timing verification in the TB62214AFNG,C8,EL - critical for closed-loop diagnostics without adding external sensors.

Can the TB62214AFNG,C8,EL operate with only a single power supply, and how is logic voltage generated?

Yes, the TB62214AFNG,C8,EL operates from a single VM supply (10–38 V) thanks to its integrated on-chip voltage regulator that generates a stable 5 V rail for internal logic. This VCC output appears on pin 41 and must be decoupled with a 0.1 μF ceramic capacitor. The regulator eliminates the need for an external 5 V supply, simplifying power architecture - a core design feature of the TB62214AFNG,C8,EL confirmed in its functional block diagram and electrical characteristics table.

What are the valid excitation modes supported by the TB62214AFNG,C8,EL, and how are they selected?

The TB62214AFNG,C8,EL supports three hardware-selectable excitation modes: two-phase (full-step), 1-2-phase (half-step), and W1-2-phase (wave drive). Selection is made via logic levels on D_MODE1 (pin 5) and D_MODE2 (pin 7): LL = standby, LH = two-phase, HL = 1-2-phase, HH = W1-2-phase. These modes directly affect step resolution, torque profile, and power consumption - all verified in the TB62214AFNG,C8,EL's phase sequence diagrams and excitation mode tables.

Does the TB62214AFNG,C8,EL include built-in protection against overtemperature and overcurrent, and how do these functions recover?

Yes, the TB62214AFNG,C8,EL integrates thermal shutdown (TSD) tripping at 150°C (typ.) and per-phase overcurrent shutdown (ISD) with 3.0 A (typ.) trip threshold. Both protections force outputs into high-impedance state. Recovery requires either cycling power or setting both D_MODE1 and D_MODE2 pins low - a deliberate design to prevent automatic restart under fault conditions. This behavior is documented in the TB62214AFNG,C8,EL's detection features section and verified in its absolute maximum ratings table.
