SERIAL INTERFACE RECEIVER AND AN OFFSET CALIBRATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240347114 titled 'SERIAL INTERFACE RECEIVER AND AN OFFSET CALIBRATION METHOD THEREOF
The abstract describes a parallel e-fuse device with two e-fuses transferring different fuse currents to an output terminal.
- The first e-fuse includes a power transistor to control the fuse current, a clamp amplifier for charging the transistor's gate, and a balance amplifier for discharging the gate.
- The clamp amplifier generates the charging current based on the difference between the feedback voltage and a reference voltage.
Potential Applications: - Circuit protection in electronic devices - Power management systems - Overcurrent protection in automotive applications
Problems Solved: - Efficient control of fuse currents - Reliable protection against overcurrent events
Benefits: - Enhanced safety in electronic systems - Improved reliability of power distribution - Cost-effective solution for overcurrent protection
Commercial Applications: - Integrated circuits - Automotive electronics - Industrial control systems
Questions about e-fuse technology: 1. How does the balance amplifier help in controlling the gate of the power transistor? The balance amplifier provides a sinking current to discharge the gate of the power transistor, ensuring precise control over the fuse current.
2. What are the advantages of using a clamp amplifier in an e-fuse device? The clamp amplifier helps in providing a charging current to the gate of the power transistor, ensuring efficient operation and reliable protection against overcurrent events.
