G7951S11U
G7951S11U - Brand New GMT IC Chips
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The G7951 contains 3 precise digital thermometers, one fan controllers,
hardware and software thermal shutdown.
The thermometers report the temperature of 3 remote sensors. The remote
sensors are diode-connected transistors typically a low-cost, easily mounted
2N3904 NPN type or the diode built-in in CPU. Remote accuracy is ±1°C for
multiple transistor manufacturer. The G7951 also support offset adjust
function via SMBus to fix the error due to different CPU diode or parasitic
resistors.
The 2-wire serial interface accepts standard System Management Bus (SMBusTM)
Write Byte, Read Byte, Send Byte, and Receive Byte commands. G7951 SMBus
address is 7ah for write and 7bh for read. And supports writting protection
function by command 20h to prevent error behavior of µP.
