Hot plug circuit, interface circuit and electronic equipment assembly

Abstract

The invention discloses a hot plug circuit, an interface circuit and an electronic equipment assembly. The hot plug circuit comprises a switch module, a capacitor module, a capacitor control module and a current limiting module, wherein a first end of the switch module is a power input terminal; a second end of the switch module is a power output terminal; a third end of the switch module is connected with a second end of the capacitor module, a fourth end of the capacitor control module and a first end of the current limiting module; a first end of the capacitor module is a power output terminal; a first end of the capacitor control module is a power input terminal; a second end of the capacitor control module is a grounding terminal; a third end of the capacitor control module is an enabling terminal; and a second end of the current limiting module is a grounding terminal. By using the hot plug circuit provided by the invention, the soft start effect can be improved during electrification and quick cut-off can be realized during power failure.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a hot-swappable circuit, an interface circuit and electronic equipment components. Background technique [0002] Hot-swapping means hot-swapping, which allows users to insert and unplug electronic equipment components, such as boards and cards, without cutting off the power supply of the equipment, without causing equipment or peripheral devices to fail, thereby improving the recovery and expansion capabilities of the system wait. [0003] If the load on the component is a capacitive load, without cutting off the power supply of the device, the moment the component is inserted into the device, the sudden connection of the power supply will have a large instantaneous impact on the component, and arc discharge will occur at the connector, and even Cause damage to the equipment; when the component is pulled out, there may be instant contact and instant disconnection at the conn...
