Document Type and Number:
WIPO Patent Application WO/2023/020020
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present disclosure are an electro-static protection device and an electronic apparatus. The electro-static protection device comprises: a P-type substrate; an N-well, which is located in the P-type substrate; a PMOS transistor, wherein the PMOS transistor comprises a gate electrode, and a first P-type heavily doped region and a second P-type heavily doped region, which are located on two sides of the gate electrode; and a pulse monitoring unit, wherein the gate electrode of the PMOS transistor is controlled by the pulse monitoring unit. The first P-type heavily doped region is connected between the P-type substrate and the N-well in a spanning manner; the P-type substrate is connected to a first bonding pad; and the second P-type heavily doped region is connected to a second bonding pad.
