Microcontroller chip: PIC16F1704
Location marker: U3
https://www.zeusbtc.com/Upload/image/202208/16595124231257596.jpgThe PIC16F1704 is an 8-bit microcontroller processor designed primarily for checking PIC circuits. For example, when the PIC pin voltage does not reach the standard value, you can reprogram the PIC by checking whether the connection between the test fixture cable and the hash board is normal. The chip operating temperature range is -40°C to 85°C.
EEPROM chip: ATH02402DMCN
Location Marker: U5

Available in an 8-pin TSSOP package, the operating voltage is between 1.7V and 3.6V. In addition, the chip has a built-in bidirectional data transmission protocol, which can store data for a long time.
MOS chip: TPHR9003NL
Position markers: Q2, Q3, Q6, Q7
https://www.zeusbtc.com/Upload/image/202208/16595124726671385.jpgThe MOS chip TPHR9003NL is mainly used to detect the voltage output of the voltage domain. By measuring the output of the power supply terminal of the hash board, it can be judged whether the MOS is short-circuited (measure the resistance between pins 1, 4, and
. If there is a 14V power supply, there will generally be a domain voltage output. Under normal circumstances, the voltage is unstable, and the lightning surge will damage the MOS.
Boost chip: MP1517DR
Location marker: U9
https://www.zeusbtc.com/Upload/image/202208/16595124922281522.jpgThe MP1517DR chip is a boost converter chip in a tiny 4mm*4mm 16-pin QFN package technology. The MP1517DR regulates the output voltage to 25V with up to 95% efficiency. The die temperature operating range is –40°C to +85°C. Its current mode regulation and external compensation components allow the MP1517DR control loop to be optimized over a wide range of input, output and load current conditions.
Boost converter chip: SY7208
Location marker: U10
