62 / 88 page  RPM-Based Fan Controller with Multiple Temperature Zones & Hardware Thermal Shutdown Datasheet DS20005251A-page 62 2013 Microchip Technology Inc. 7.26 Gain Register The Gain Register stores the gain terms used by the proportional and integral portions of the RPM- based Fan Speed Control Algorithm. These terms will affect the FSC closed loop acquisition, overshoot, and settling as would be expected in a classic PID system. 7.27 Fan Spin Up Configuration Register The Fan Spin Up Configuration Register controls the settings of Spin Up Routine. Bit 7 - 6 - DRIVE_FAIL_CNT[1:0] - Determines how many update cycles are used for the Drive Fail detection function as shown in Table 7.42, "DRIVE_FAIL_CNT[1:0] Bit Decode". This circuitry determines whether the fan can be driven to the desired tach target. Table 7.39 Gain Register ADDR R/W REGISTER B7 B6 B5 B4 B3 B2 B1 B0 DEFAULT 45h R/W Gain Register - - GAIND[1:0] GAINI[1:0] GAINP[1:0] 2Ah Table 7.40 Gain Decode GAIND OR GAINP OR GAINI [1:0] RESPECTIVE GAIN FACTOR 10 00 1x 01 2x 1 0 4x (default) 11 8x Table 7.41 Fan Spin Up Configuration Register ADDR R/W REGISTER B7 B6 B5 B4 B3 B2 B1 B0 DEFAULT 46h R/W Fan Spin Up Configuration DRIVE_FAIL_ CNT [1:0] NOK ICK SPIN_LVL[2:0] SPINUP_TIME [1:0] 19h Table 7.42 DRIVE_FAIL_CNT[1:0] Bit Decode DRIVE_FAIL_CNT[1:0] NUMBER OF UPDATE PERIODS 10 00 Disabled - the Drive Fail detection circuitry is disabled (default) 01 16 - the Drive Fail detection circuitry will count for 16 update periods |
