Product details
Overview
TB67S111PG from Toshiba Electronic Devices & Storage Corporation is a full-parallel-input unipolar stepper motor and solenoid driver IC with four independent N-channel sink outputs, 80 V output voltage rating, 1.5 A per channel absolute maximum output current, and integrated thermal shutdown (TSD) and overcurrent detection (ISD). It drives industrial valve actuators and small unipolar stepper motors in automated dispensing systems.
For engineers reviewing the TB67S111PG datasheet, TB67S111PG pinout, TB67S111PG application, or TB67S111PG equivalent, this page delivers verified electrical parameters, real-world thermal behavior, functional pin mapping, and validated alternative drivers for solenoid and unipolar motor control designs.
Technical Context
The TB67S111PG implements a BiCD silicon monolithic architecture enabling high-voltage (80 V) and high-current (1.5 A/ch) switching while integrating logic-level input interface, internal VCC regulator, and open-drain ERR fault signaling. Its 4-channel sink topology supports direct parallel control of unipolar stepper windings or independent solenoids without external transistors.
Each output features a low-RDS(on) MOSFET (0.25 Ω typ.), regenerative diode (VFN = 1.1 V typ. at 1.5 A), and dedicated ISD sensing with 3.0 A threshold (design value). TSD activates at 170 °C junction temperature with 5.0 μs masking time and automatic recovery after 320 μs off-time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output configuration | 4-channel N-ch sink driver with COM terminal; enables unipolar stepper phase control or independent solenoid actuation |
| Motor supply range (VM) | 10–40 V operating; 45 V absolute max - supports 24 V industrial rails with margin for back-EMF spikes |
| Output voltage withstand | 80 V max - handles inductive kickback from solenoids and stepper windings without external clamping |
| Per-channel output current | 0.75 A typical / 1.5 A absolute max - sufficient for 12–24 V solenoids ≤1.2 W or 5–7.5° unipolar steppers |
| Logic input compatibility | VIH = 2.0–5.5 V; VIL = 0–0.8 V - interfaces directly with 3.3 V or 5 V microcontrollers without level shifting |
| Thermal protection | TSD threshold = 170 °C (typ.); auto-recovery after 320 μs - prevents permanent damage during transient overload |
| Overcurrent detection | ISD threshold = 3.0 A (design value); 1.25 μs blanking time - suppresses false triggers from PWM switching noise |
Pinout & Package
Package: DIP16-P-300-2.54A (16-pin dual in-line package, 300 mil width, 2.54 mm pitch, 1.11 g typical weight).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Internal regulator monitor | Supplies regulated 5.0 V (±0.25 V) to logic core; must be decoupled with 0.1 μF ceramic capacitor |
| ERR (Pin 2) | Open-drain fault output | Pulls low during TSD activation; requires external 10–100 kΩ pull-up to VCC for system-level fault monitoring |
| IN1–IN4 (Pins 3,6,7,8) | Digital control inputs | Directly enable/disable OUT1–OUT4; high = ON, low = OFF; hysteresis ≥100 mV prevents noise-induced toggling |
| GND (Pins 4,5,12,13) | Ground reference | Four dedicated GND pins minimize ground bounce; all must connect to single-point PCB ground plane |
| OUT1–OUT4 (Pins 14,11,10,9) | N-ch sink outputs | Each switches load to GND; rated 80 V/1.5 A; RDS(on) = 0.25 Ω ensures <0.6 W conduction loss at 1.5 A |
| COM (Pin 15) | Common return path | Connects to positive side of solenoids or unipolar stepper center tap; must route with low-inductance trace |
| VM (Pin 16) | Motor power input | High-current input (up to 6 A total); requires thick copper pour and separate power plane from logic ground |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 4-channel sink driver | Eliminates need for external MOSFETs or Darlington arrays when driving 24 V solenoids or 5–7.5° unipolar steppers |
| Built-in overcurrent detection (ISD) | Per-channel current limiting with 3.0 A threshold and 1.25 μs noise immunity window prevents false trips during PWM commutation |
| Thermal shutdown with auto-recovery | Triggers at 170 °C junction temperature and restores operation after 320 μs off-time - avoids latching faults in intermittent duty cycles |
| Low RDS(on) output stage | 0.25 Ω typical on-resistance reduces power dissipation to 0.56 W per channel at 1.5 A, easing thermal design |
| VCC regulator with pull-up capability | Stable 5.0 V internal supply powers logic and serves as pull-up source for ERR pin - removes need for external regulator |
Applications
| Industrial Valve Control | Automated Fluid Dispensing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar solenoid and unipolar motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB67S109AFG | Same BiCD process, 4-channel sink, but rated for 40 V VM (vs. 45 V abs max) and 1.2 A/ch (vs. 1.5 A abs max); no ERR pin | Lacks thermal fault reporting; lower voltage/current headroom limits use in high-back-EMF or 36 V systems | Select when cost sensitivity outweighs need for fault visibility and 24 V+ margin; verify thermal derating on PCB |
| STSPIN220 | 3-channel sink driver with integrated current regulation (not fixed ISD); 45 V VM, 1.3 A/ch; SPI interface instead of parallel INx | Requires microcontroller SPI communication and current-sense resistor; no native parallel control mode | Choose for closed-loop current control or space-constrained designs where serial interface is acceptable |
Compared with TB67S111PG, TB67S109AFG sacrifices fault signaling and margin for lower BOM cost, while STSPIN220 trades parallel simplicity for programmable current control and smaller QFN packaging - neither offers pin-compatible replacement, and both require layout and firmware changes.

FAQ
What is the maximum continuous output current per channel for the TB67S111PG?
The TB67S111PG has an absolute maximum output current rating of 1.5 A per channel, but its typical continuous output current is 0.75 A under standard operating conditions (Ta = 25°C, VM = 24 V). Sustained operation above 0.75 A requires careful thermal management, including PCB copper area optimization and ambient temperature control, to prevent triggering thermal shutdown.
Does the TB67S111PG support unipolar stepper motor full-step sequencing?
Yes, the TB67S111PG supports full-step unipolar stepper motor operation using its four independent sink outputs (OUT1–OUT4) and common (COM) terminal. By applying parallel logic signals to IN1–IN4, the device directly controls each winding in sequence - for example, activating IN1 only energizes phase A, while IN1+IN2 energizes A+B, matching standard unipolar full-step patterns.
How does the ERR pin function on the TB67S111PG?
The ERR pin on the TB67S111PG is an open-drain N-channel MOSFET output that pulls low during thermal shutdown detection (TSD). In normal operation, it remains in high-impedance state. To use it, connect a 10–100 kΩ pull-up resistor to VCC. When TSD activates, the internal MOSFET turns on, pulling ERR low - providing a hardware-level fault signal for microcontroller interrupt or system watchdog monitoring.
Can the TB67S111PG drive loads with supply voltages above 24 V?
Yes, the TB67S111PG supports motor supply (VM) voltages from 10 V to 40 V in normal operation, with an absolute maximum rating of 45 V. It is qualified for 24 V industrial systems but can also operate reliably at 36 V, provided thermal limits are respected and back-EMF transients remain within the 80 V output voltage withstand rating - always verify worst-case inductive kickback in your specific load.
What is the purpose of the COM pin on the TB67S111PG?
The COM pin on the TB67S111PG serves as the common high-side connection point for solenoid coils or unipolar stepper motor center taps. All four OUTx pins are low-side (sink) switches; COM connects to the positive rail of the load, completing the current path when any OUTx is active. Proper low-inductance routing of COM is critical to avoid voltage spikes and ensure stable switching performance.
