Self-destruction circuit of tablet personal computer storage device

Abstract

The invention discloses a self-destruction circuit of a tablet personal computer storage device. The self-destruction circuit comprises a detecting unit, a switching unit and a destruction unit. The detecting unit is used for detecting whether a tablet personal computer is illegally disassembled or not and generating a corresponding computer disassembling signal; the switching unit is electrically connected to the detecting unit and used for connecting a direct current power source to the destruction unit according to the corresponding computer disassembling signal and providing input voltage to the destruction unit; the destruction unit comprises a voltage boosting circuit which is electrically connected to the switching unit and used for boosting the input voltage provided by the switching unit so that destruction voltage can be generated and outputting the destruction voltage to signal pins of the tablet personal computer storage device. Device cost can be reduced, circuit integration is convenient, and the self-destruction circuit can be widely applied to the tablet personal computer and other precise devices which are small in size and high in requirement.

Description

[0001] technical field [0002] The invention relates to a self-destruction circuit, in particular to a self-destruction circuit of a tablet computer storage device. [0003] Background technique [0004] With the development of informatization, the scope of use of tablet computers has also been greatly popularized. People will store data in the storage devices of tablet computers in the form of electronic documents, such as NAND Flash, Tf-Card, etc. In order to prevent stored data from being stolen, the existing technology can protect data through various software or hardware configurations, such as dismantling self-destruct circuit, the purpose of this dismantling self-destruct circuit is to prevent the storage device from being obtained by disassembling the storage device on the data. At present, the self-destruction circuit of the dismantling machine on the market mainly uses the programmer to control the relay to charge the large capacitor and discharge it instantaneo...

Problems solved by technology

However, this type of self-destruct circuit requires a capacitor of several thousand microfarads. Take the SIKOREL125 25v3000uf 3300uf of EPCOS (Siemens) as an example. The volume of this capacitor is 21x38mm (diameter*height). It reduces the cost and is not convenient for circuit integration, so it is obviously not suitable for small size and high precision devices such as tablet computers.
