Product details
Overview
TB67H410NG from Toshiba Electronic Devices & Storage Corporation is a PWM chopper-type dual-channel brushed DC motor driver IC fabricated in BiCD process, rated for 50 V maximum VM supply and delivering up to 2.5 A per channel (Small mode) or 5.0 A combined (Large mode), with integrated thermal shutdown, over-current detection, and internal regulator - used in industrial automation actuators, robotic joint controllers, and precision motion stages.
For engineers reviewing the TB67H410NG datasheet, TB67H410NG pinout, TB67H410NG application, or TB67H410NG equivalent, key selection considerations include its SDIP24 package thermal performance, dual-bridge vs. parallel H-bridge configuration flexibility, analog/digital blanking time control, current-sense resistor–based current regulation, and compatibility with 3.3 V/5 V logic interfaces.
Technical Context
The TB67H410NG implements a dual H-bridge architecture with independent control of Bridge A (INA1/INA2/PWMA) and Bridge B (INB1/INB2/PWMB), supporting four operation modes per bridge: CW, CCW, brake, and stop. Its PWM chopper operates at 40–150 kHz (typ. 70 kHz), with fixed 37.5% mixed-decay timing and digitally programmable blanking via TBLKAB pin.
It integrates an internal 5.0 V ±2.5% regulator powered from VM, enabling single-supply operation; current regulation uses external sense resistors (RSA/RSB) and user-configurable VREF (0–4.0 V), with gain of 1/5.0 (typ.). HBMODE pin selects between Small mode (dual independent motors) and Large mode (single high-current motor using paralleled bridges).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VM Supply Range | 10 V to 47 V - supports 12 V/24 V industrial rails; absolute max 50 V (non-recoverable damage if exceeded) |
| Output Current Rating | 2.5 A per channel (Small mode) or 5.0 A total (Large mode) - requires thermal derating above 25°C ambient (14.2 mW/°C) |
| On-Resistance (HS+LS) | 0.8 Ω (typ.) - enables <1.2 W conduction loss at 2.5 A, critical for thermally constrained SDIP24 layout |
| Chopping Frequency | 70 kHz (typ.), adjustable 40–150 kHz via OSCM external RC - higher fchop reduces current ripple but increases gate loss |
| VREF Input Range | 0 V to 4.0 V - sets peak output current as IOUT(max) = VREF × (1/5.0) / RRS; e.g., 3.0 V + 0.51 Ω → 1.18 A |
| Digital Blanking Time | 3.6 µs (TBLKAB=L) or 5.4 µs (TBLKAB=H) - suppresses false over-current detection during motor commutation transients |
| Logic Input Thresholds | VIN(H) ≥ 2.0 V, VIN(L) ≤ 0.8 V - compatible with both 3.3 V and 5 V microcontroller GPIO without level shifters |
| Protection Features | Thermal shutdown (Tj ≥ 160°C typ.), over-current detection (ISD threshold 3.0 A typ.), and power-on reset (VMR = 8.0 V typ.) - all force standby mode until cleared |
Pinout & Package
P-SDIP24-0723-1.78-001: 24-pin plastic small-outline dual in-line package (SDIP), 7.23 mm × 15.4 mm body, 1.78 mm height, through-hole mount, 1.3 g typical weight. Designed for high-power dissipation with multiple GND pins (Pins 1, 3, 6, 19, 22, 24) and dedicated VM (Pin 7) and sense-return paths.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 19, 22, 24 | GND | Power ground return for motor current, sense circuitry, and logic - must be connected to single-point PCB ground plane |
| 2, 23 | OUTB− / OUTA− | Bridge B / A low-side output - connects to motor winding negative terminal; shares current path with RSA/RSB sense |
| 4, 21 | OUTB+ / OUTA+ | Bridge B / A high-side output - connects to motor winding positive terminal; forms full H-bridge with corresponding OUTx− |
| 5, 20 | RSB / RSA | Bridge B / A current sense output - connects to external shunt resistor (RRS); voltage drop scaled by 1/5.0 for current feedback |
| 7 | VM | Motor power supply input - supplies both H-bridge power stage and internal regulator; must be decoupled near pin |
| 8 | VCC | Internal regulator output monitor - provides stable 5.0 V for logic; not intended as system VCC source |
| 9 | VREF | Reference voltage input - sets current limit threshold; 0–4.0 V range allows precise analog current programming |
| 10 | HBMODE | H-bridge mode select - Low = Small mode (dual independent motors), High = Large mode (parallel bridges for 5 A) |
| 11 | OSCM | Oscillator frequency set - external RC network (e.g., 270 pF + 5.1 kΩ) sets fOSCM ≈ 1.12 MHz → fchop ≈ 70 kHz |
| 12–13, 16–17 | INA1/INA2, INB1/INB2 | Bridge A/B direction control inputs - define CW/CCW/brake/stop per bridge; require simultaneous Low for standby |
| 14–15 | PWMA / PWMB | Bridge A/B short-brake inputs - active-High forces rapid motor current decay; independent of INA/INB state |
| 18 | TBLKAB | Digital blanking time select - configures tBLK duration to reject noise during commutation; critical for reliable ISD operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridges with parallel mode | Configurable via HBMODE pin: two 2.5 A motors (Small) or one 5 A motor (Large) - eliminates need for external paralleling |
| Integrated current regulation with external RRS | Uses VREF and sense-resistor feedback to maintain constant peak current; eliminates external op-amp/current-loop components |
| Programmable chopping frequency | fchop set by external OSCM RC (40–150 kHz range) - balances current ripple, EMI, and switching losses per application |
| Dual-stage blanking (analog + digital) | Analog tBLK = 400 ns (fixed) + digital tBLK = 3.6/5.4 µs (selectable) - prevents false ISD triggering during motor turn-on/off |
| Single-supply operation with on-chip regulator | Internal 5.0 V regulator powered from VM - removes need for separate logic rail, simplifying power tree in 24 V systems |
| Comprehensive fault protection | Independent TSD (160°C typ.) and ISD (3.0 A typ.) circuits that force standby mode - enables safe recovery without MCU intervention |

FAQ
What is the maximum continuous output current supported by the TB67H410NG in Small mode?
The TB67H410NG supports up to 2.5 A per channel continuously in Small mode (HBMODE = Low), provided thermal design maintains junction temperature below 120°C. At 25°C ambient, derating is 14.2 mW/°C; actual usable current depends on PCB copper area, airflow, and heatsinking - Toshiba recommends limiting to ≤1.75 A (70% of absolute max) for sustained operation.
How does the HBMODE pin affect the TB67H410NG's operation and pin functionality?
When HBMODE = Low, the TB67H410NG operates in Small mode: Bridge A (INA1/INA2/PWMA) and Bridge B (INB1/INB2/PWMB) function independently. When HBMODE = High, it enters Large mode: Bridges A and B parallel to deliver 5.0 A total, with INB1/INB2/PWMB disabled and OUTA+/OUTA−/OUTB+/OUTB−/RSA/RSB internally joined - requiring external PCB traces to connect matching pins.
Can the TB67H410NG operate from a single 24 V supply without an external logic regulator?
Yes. The TB67H410NG integrates an internal regulator that generates a stable 5.0 V (±2.5%) output from the VM supply (Pin 7), powering all logic circuitry. This allows full operation from a single 24 V rail - VCC (Pin 8) is a monitor node, not a power input, and no external 5 V regulator is needed for logic-level interfacing.
What is the purpose of the TBLKAB pin on the TB67H410NG, and how does it impact motor control reliability?
The TBLKAB pin selects digital blanking time (3.6 µs at L, 5.4 µs at H) to suppress false over-current detection during motor commutation transients. Combined with fixed 400 ns analog blanking, it prevents ISD circuit mis-triggering caused by back-EMF spikes or inductive kickback - ensuring stable PWM chopper operation in noisy industrial environments where the TB67H410NG is deployed.
How is output current programmed on the TB67H410NG, and what external components are required?
Output current is programmed using VREF (Pin 9) and external sense resistors RSA/RSB (Pins 20/5). Peak current is calculated as IOUT(max) = VREF × (1/5.0) / RRS. For example, with VREF = 2.5 V and RRS = 0.25 Ω, TB67H410NG delivers 2.0 A. No op-amps or DACs are needed - VREF can be set via voltage divider or DAC, and RRS must be low-inductance, ±1% tolerance.
