Manufacturer:PANASONIC Description:The TC650/TC651 acquire and convert their junction temperature (TJ) information from an on-chip solid-state sensor with a typical accuracy of 1C. The temperature data is digitally stored in an internal register. The register is compared with pre-defined threshold values. The six threshold values are equally distributed over a pre-defined range of temperatures (see Table 3-1 and Table 3-2). The TC650/TC651 control the speed of a DC brushless fan using a fractional speed control scheme. The output stage requires only a 2N2222-type small-signal BJT for fans up to 300mA. For larger current fans (up to 1 Amp) a logic-level N-channel MOSFET may be used. In addition to controlling the speed of the fan, the TC650/TC651 include an on-chip over-temperature alarm (TOVER) that gives a low signal when the temperature of the chip exceeds TH by 10C, (typical). This feature eliminates the need for a separate temperature sensor for over-temperature monitoring. |
