ELECTROSTATIC PROTECTION CIRCUIT, POWER MANAGEMENT CHIP, AND DISPLAY TERMINAL - A simplified explanation of the abstract

This abstract first appeared for US patent application 17622792 titled 'ELECTROSTATIC PROTECTION CIRCUIT, POWER MANAGEMENT CHIP, AND DISPLAY TERMINAL

Simplified Explanation

The patent application describes an electrostatic protection circuit, a power management chip, and a display terminal. The electrostatic protection circuit consists of a level shift unit, a power management unit, and a clamping module. The clamping module receives an electrostatic detection signal and outputs a fault detection signal. The output terminal of the clamping module maintains a high electrical potential until the power management unit stops operating.

  • The electrostatic protection circuit includes a level shift unit, power management unit, and clamping module.
  • The clamping module receives an electrostatic detection signal.
  • The clamping module outputs a fault detection signal.
  • The output terminal of the clamping module maintains a high electrical potential until the power management unit stops operating.

Potential Applications:

  • Electronics manufacturing: The electrostatic protection circuit can be used in electronic devices to protect them from electrostatic discharge during manufacturing processes.
  • Consumer electronics: The circuit can be integrated into consumer electronic devices to prevent damage caused by electrostatic discharge.

Problems Solved:

  • Electrostatic discharge damage: The circuit prevents damage to electronic devices caused by electrostatic discharge, which can occur during manufacturing or regular use.

Benefits:

  • Enhanced device protection: The circuit provides effective protection against electrostatic discharge, ensuring the longevity and reliability of electronic devices.
  • Improved manufacturing processes: By incorporating the circuit into manufacturing processes, the risk of electrostatic discharge damage to electronic components is minimized, leading to higher production yields and reduced costs.


Original Abstract Submitted

An electrostatic protection circuit, a power management chip, and a display terminal are provided. The electrostatic protection circuit includes a level shift unit and a power management unit. The electrostatic protection circuit also includes a clamping module. An input terminal of the clamping module receives an electrostatic detection signal. An output terminal of the clamp module outputs a fault detection signal. The output terminal of the clamp module continues to output a high electrical potential when the electrostatic detection signal transits from a low electrical potential to the high electrical potential until the power management unit stops operating.
