Product details
Overview
TB67H400AFNG from Toshiba is a monolithic PWM chopper-type dual-channel brushed DC motor driver IC fabricated in BiCD process, rated for 50 V supply and delivering up to 4.0 A per channel (Small mode) or 8.0 A in parallel Large mode, with integrated thermal shutdown, over-current detection, and internal VCC regulator - used in industrial automation motion control systems requiring precise current-regulated H-bridge operation.
For engineers reviewing the TB67H400AFNG datasheet, TB67H400AFNG pinout, TB67H400AFNG application, or TB67H400AFNG equivalent, key selection considerations include its dual-mode H-bridge configuration (Small/Large), programmable chopping frequency via OSCM, 0.49 Ω typical on-resistance, mixed-decay current control with fixed 37.5% decay timing, and dual-channel independent logic interface with digital blanking time control.
Technical Context
The TB67H400AFNG implements a dual-H-bridge architecture with two independent motor control channels (A and B), each supporting four operation modes (CW/CCW/Brake/Stop) and two drive modes (PWM-controlled constant current or direct PWM). Its internal oscillator (OSCM) sets the chopper reference frequency (fOSCM = 0.64–2.4 MHz), which divides by 16 to yield fchop (40–150 kHz), directly governing current ripple and decay behavior.
It integrates analog and digital blanking (Analog tBLK = 400 ns typ.; Digital tBLK = 3.6–5.4 μs depending on TBLKAB state) to suppress false over-current detection during switching transients, and features dedicated current-sense pins (RSA/RSB) with VREF-based peak current setting (IOUT(max) = VREF / 5.0 / RRS). HBMODE pin selects between independent dual-motor (Small mode) or paralleled single-motor (Large mode) operation, with distinct pin functional mapping in Large mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VM) | 10–47 V operating range; absolute max 50 V - defines compatible motor bus voltage and system power architecture. |
| Output Current Rating | 4.0 A per channel (Small mode); 8.0 A total (Large mode) - determines motor torque capability and heatsink sizing. |
| On-Resistance (HS+LS) | 0.49 Ω typical - directly impacts conduction loss (Pcond ≈ I² × Ron) and thermal design margin. |
| Chopping Frequency (fchop) | 40–150 kHz (typ. 70 kHz at fOSCM = 1.12 MHz) - higher values reduce current ripple but increase switching loss. |
| VREF Input Range | 0–4.0 V - sets peak output current via external sense resistor (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) - prevents false ISD triggering during H-bridge commutation. |
| Logic Input Thresholds | VIN(H) ≥ 2.0 V, VIN(L) ≤ 0.8 V - ensures compatibility with 3.3 V or 5 V microcontroller GPIOs. |
| Thermal Shutdown (TSD) | Triggers at 145–175 °C junction temperature - protects against sustained overload but requires external thermal management. |
Pinout & Package
Package: HTSSOP48-P-300-0.50 (48-pin thermally enhanced thin shrink small outline package, 0.5 mm pitch, exposed pad for GND and thermal dissipation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OSCM | Oscillator frequency setting | Connects external RC network (e.g., 5.1 kΩ + 270 pF) to set fOSCM and thus fchop. |
| INA1/INA2, INB1/INB2 | Motor direction control inputs | Set CW/CCW/Brake/Stop for each channel; all low enables standby mode. |
| PWMA/PWMB | Short-brake control inputs | Enable active short-braking of respective motor windings when high. |
| HBMODE | H-bridge operation mode select | Low = independent dual-channel (Small mode); High = paralleled single-channel (Large mode). |
| RSA/RSB | Current sense feedback | Connect to low-side sense resistors; feeds internal comparator for constant-current regulation. |
| VREF | Reference voltage input | Sets peak motor current via IOUT = VREF / 5.0 / RRS; 0–4.0 V range. |
| OUTA+/OUTA−, OUTB+/OUTB− | H-bridge output terminals | Drive motor windings; paired pins (e.g., OUTA+ ×2) must be shorted externally in PCB layout. |
| GND (×10 pins) | Ground return paths | Multiple dedicated GND pins minimize ground impedance and improve noise immunity and thermal conduction. |
| VM | Motor power supply input | High-current path (up to 8 A); requires wide copper pour and low-inductance routing. |
| VCC | Internal regulator monitor | Supplies internal logic; regulated 4.75–5.25 V output - decoupling capacitor required. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent H-bridge control | Enables simultaneous bidirectional control of two brushed DC motors with full four-quadrant operation per channel. |
| Configurable PWM chopper frequency | External OSCM RC network allows tuning fchop from 40–150 kHz to balance current ripple vs. switching loss. |
| Mixed-decay current regulation | Fixed 37.5% slow/fast decay ratio optimizes torque smoothness and efficiency in constant-current mode. |
| Integrated protection circuits | Thermal shutdown (TSD), over-current detection (ISD), and power-on reset (POR) provide fault containment without external components. |
| Parallel Large mode operation | HBMODE = H reconfigures both bridges into a single 8 A H-bridge, doubling current capacity for high-torque single-motor applications. |
| Dual-blanking time control | Analog (400 ns) + digital (3.6/5.4 μs) blanking prevents false ISD trips during transient voltage spikes at switch transitions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar brushed DC motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DRV8876PWPR | Single-channel 6.5 A H-bridge; integrated current sense amplifier (not resistor-based); no Large mode; 4.5–45 V VM range. | Best for space-constrained single-motor designs needing analog current monitoring; lacks dual-channel or parallel mode. | Select DRV8876PWPR when board area is limited and analog current telemetry is preferred over discrete sense resistors. |
| MP6532GQ-Z | Dual-channel 3.5 A (per channel); 4.5–35 V VM; no programmable fchop; fixed 25 kHz chopping; no HBMODE or Large mode. | Suitable for lower-voltage consumer robotics; simpler setup but less flexible current control and no high-current parallel option. | Choose MP6532GQ-Z for cost-sensitive, low-complexity dual-motor applications below 35 V where 70 kHz ripple reduction is not required. |
Compared with DRV8876PWPR and MP6532GQ-Z, the TB67H400AFNG uniquely supports both independent dual-motor control and reconfigurable 8 A single-motor operation, offers user-tunable chopping frequency, and delivers higher voltage (47 V) and current (8 A) capability - making it optimal for industrial-grade motion systems demanding flexibility and robustness.

FAQ
What is the maximum continuous output current for TB67H400AFNG in Small mode?
The TB67H400AFNG is rated for 4.0 A per channel in Small mode under absolute maximum conditions. However, Toshiba recommends limiting continuous operation to ≤2.8 A (70% of rating) to ensure safe thermal performance. Actual usable current depends on PCB copper area, ambient temperature, and airflow - derating is required above 25°C ambient at 9.2 mW/°C.
How does the HBMODE pin affect TB67H400AFNG functionality?
When HBMODE = L, TB67H400AFNG operates in Small mode with two independent H-bridges for dual-motor control. When HBMODE = H, it enters Large mode: channels A and B are internally paralleled into a single 8 A H-bridge, with only INA1/INA2/PWMA active - INB1/INB2/PWMB become invalid. External PCB connections (RSA/RSB, OUTA+/OUTB+, etc.) must be shorted per datasheet guidance.
Can TB67H400AFNG operate without an external current-sense resistor?
No - TB67H400AFNG requires external sense resistors (RSA and RSB) connected between OUTx− and GND to enable its constant-current PWM chopper function. The IC compares the voltage across these resistors to VREF to regulate peak motor current. Omitting them disables current limiting and risks device or motor damage under overload.
What is the purpose of the TBLKAB pin on TB67H400AFNG?
The TBLKAB pin selects digital blanking time duration to suppress false over-current detection during H-bridge switching transients. At TBLKAB = L, digital blanking is ~3.6 μs; at TBLKAB = H, it extends to ~5.4 μs. This timing is added to the fixed 400 ns analog blanking, ensuring reliable ISD operation during motor commutation and direction changes.
Does TB67H400AFNG include an internal voltage regulator?
Yes - TB67H400AFNG integrates an internal VCC regulator that supplies stable 4.75–5.25 V to internal logic circuits from the VM supply. The VCC pin is an output requiring a 10 µF ceramic decoupling capacitor to ground. This eliminates the need for an external 5 V rail while simplifying system power architecture.
How is the chopping frequency (fchop) calculated for TB67H400AFNG?
fchop is derived from the OSCM oscillator frequency: fchop = fOSCM / 16. fOSCM itself is set by external components on the OSCM pin: fOSCM ≈ 1 / [0.56 × (COSC × (ROSC + 500))]. For example, with COSC = 270 pF and ROSC = 5.1 kΩ, fOSCM ≈ 1.12 MHz → fchop ≈ 70 kHz. Accuracy is ±15% due to component tolerances and process variation.
