摘要： A pad circuit includes a pad, a gate driving circuit, a voltage selection circuit, and an ESD detection/avoiding circuit. The gate driving circuit is used to discharge the ESD induced current. The ESD detection/avoiding circuit is used to isolate the ESD induced voltage. The voltage selection circuit selects a higher voltage from a power/ground terminal and the pad and outputs it to the gate driving circuit, so that the pad circuit can be used for the programming and 1/0 operations.

摘要： An electrostatic discharge (ESD) protection circuit is electrically connected to a core circuit for preventing ESD charges from reaching the core circuit. The ESD protection circuit includes a pad, a pass transistor, a transistor, a capacitor, a resistor, and a delay trigger unit. The pass transistor controls passage of charges from the pad to the core circuit. The transistor sinks ESD charges during an ESD zapping event. The capacitor and the resistor couple voltage at the pad to a control electrode of the transistor for turning on the transistor during the ESD zapping event. The delay trigger unit retards transmission of low voltage to a control electrode of the pass transistor for keeping the pass transistor turned off during the ESD zapping event.
摘要翻译：静电放电（ESD）保护电路电连接到核心电路，以防止ESD电荷到达核心电路。 ESD保护电路包括焊盘，传输晶体管，晶体管，电容器，电阻器和延迟触发单元。传输晶体管控制电荷从焊盘到核心电路的通过。在ESD切换事件期间，晶体管吸收ESD电荷。电容器和电阻器将焊盘处的电压耦合到晶体管的控制电极，用于在ESD切换事件期间导通晶体管。延迟触发单元延迟低电压传输到传输晶体管的控制电极，以在ESD切换事件期间保持传输晶体管截止。
