Without the datasheet’s thermal resistance data (junction-to-ambient, ( R_\theta JA \approx 35^\circ C/W ) for DIP with no heatsink), beginners often drive 1.5A through all four channels continuously, causing thermal shutdown. The datasheet provides the necessary thermal derating curves.
Before diving into technical details, here is the most reliable source for the A68064 datasheet:
Warning: Avoid random “datasheet.net” or “pdf1.alldatasheet.com” clones unless cross-referenced. They often host scanned copies from the 1990s with missing pages or OCR errors.
Even with the correct a68064 datasheet link, issues can arise. Here is a troubleshooting table based on the fault conditions explicitly listed in the datasheet.
| Symptom | Likely Cause | Datasheet Reference | Fix | |---------|--------------|---------------------|-----| | Outputs stay off, FAULT pin low | Overcurrent or thermal shutdown | Section: "Protection Circuits" | Check load impedance; measure if >2A. Allow cooling. | | One channel works, others not | Individual channel OCP trip | Section: "OCP Blanking Time" | Increase blanking time capacitor on VREG (if external). Otherwise, reduce inrush. | | IC heats up quickly | High ( R_DS(on) ) due to insufficient gate drive | Section: "VDD vs RDS(on)" graph | Ensure VDD ≥ 4.5V for minimum resistance. | | Motor steps irregularly | PGND and LGND shared with high current | Section: "Grounding Recommendations" | Separate PGND and LGND, connect only at IC pin 2 and 8. | | FAULT triggers at startup only | Inrush current exceeding OCP threshold | Section: "OCP Response Time" | Add soft-start via PWM of ENABLE pin or add series inductor. |
If you are designing a new circuit or cannot source the A68064, modern equivalents are superior in performance and size. Consider the following modern alternatives:
Summary: The A68064 is a legacy DMOS full-bridge motor driver. While reliable, it is obsolete. For new designs, a modern TI DRV or newer Allegro driver is recommended.

The A68064 is a versatile component primarily used in power management and switching. While documentation varies, it is most commonly described as a high-performance N-channel MOSFET or a thyristor diode in a TO-220 package. Typical Value (Reference Only) Package Type TO-220 (Standard for heat dissipation) Voltage Rating Up to 800V Current Rating 10A (Continuous) Operating Temperature -40°C to 105°C Primary Use AC/DC Power Control, Motor Drivers Pinout Configuration (TO-220 Package)
For the MOSFET version of the A68064, the pinout follows the standard three-pin configuration: Gate (G): Used to trigger or control the switching state.
Drain (D): Connects to the high-voltage load or power supply.
Source (S): Typically connected to the circuit ground or the low side. Summary: The A68064 is a legacy DMOS full-bridge
Metal Tab: The exposed tab is internally connected to the Drain and is used for mounting to a heat sink to prevent overheating. Common Applications
Engineers often use the A68064 in systems where mechanical robustness and high power handling are required:
Motor Control: Providing stable switching for DC and AC motor drives.
Power Supplies: Used in switching regulators and UPS systems.
Industrial Automation: Reliable for high-speed switching in PLC interface circuits.
Display Drivers: Acting as a latch driver to maintain stable data for LED or LCD segments. Alternatives and Equivalents
If the original A68064 is unavailable, professionals often look for equivalents in the TO-220 footprint with similar voltage and current ratings. Common replacements include standard high-voltage MOSFETs from manufacturers like STMicroelectronics or ON Semiconductor, though you should always verify the Gate Trigger Voltage in the original datasheet before swapping.
When the A68064 arrived on a dusty pallet at the small lab on the edge of town, no one noticed at first. It was just another microcontroller chip in a sea of components — a rectangular slab of matte black with a row of gold legs, labelled A68064 in a neat stencil that suggested industrial confidence.
