The a68064!
Note: Ensure you verify the specific manufacturer if your component is a different part number, such as the Tyco Electronics 68064 crimping tool which shares the same numerical designation. A68064 | Teccor | Varactors - Lisleapex a68064 datasheet link
Used as a latch driver for memory systems and display interfaces. The a68064
| 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. | | Symptom | Likely Cause | Datasheet Reference
