ASC7531A
Description
The a SC7531 is a high-precision CMOS temperature sensor and voltage monitor with Simple Serial Transport (SST) patible serial digital interface, intended for use in PC hardware monitor applications. munication of device capabilities, temperature and voltage readings take place over the high-speed bi-directional SST interface. The SST temperature sensor provides a means for an analog signal to travel over a digital bus enabling remote temperature sensing in areas previously not monitored in the PC. The temperature sensor supports an internal and external thermal diode. a SC7531A is used with 2N3904 transistor connected as a remote diode, a SC7531B is used with CPU substrate diode. The a SC7531 is available in MSOP-10 surface mount package.
