Title:
CHIP BURNING CIRCUIT AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/015110
Kind Code:
A1
Abstract:
A chip burning circuit (110) and system (10), wherein said circuit (110) is applied to the main board of an electronic device, a first switch (130) is provided on the outer surface of the electronic device, the first switch (130) being connected to a system power supply circuit (111) and controlling the electronic device to switch on or off, said circuit (110) comprising: a switch control circuit (112), connected to the first switch (130) and a universal serial bus (USB) circuit (120) respectively, wherein the USB circuit (120) is connected to a burning mainframe (200) by means of a USB connection circuit (300); a second switch (113), connected to the switch control circuit (112) and a processing chip (115) respectively; a chip power supply circuit (114), connected to the USB circuit (120) and the processing chip (115) respectively, such that when the USB circuit (120) is connected, power is supplied to the processing chip (115), and when the first switch (130) is closed and the USB circuit (120) is in a connected state, the switch control circuit (112) controls the second switch (113) to close so that the processing chip (115) carries out chip burning. By means of the chip burning circuit (110) being provided with the switch control circuit (112) and chip power supply circuit (114), startup and reuse of the burning function are achieved by the first switch (130), thus solving the problem whereby chips cannot be burned within electronic devices.
