lb11867fv no.a0195-6/9 *6. rmi pin minimum speed setting pin. perform pull-up with 5vreg when this pin is not to be used. if the ic power supply is likely to be turned off first when the pin is used with external power supply, be sure to insert the current limiting resistor to prevent inflow of large current. (the same applies to the vth pin.) *7. vth pin speed control pin. connect this pin to gnd when it is not used (at full speed). for the control method, refer to the timing chart. for control with pulse input, insert the current limiting resistor and use the pin with the frequency of 20k to 100khz (20khz to 50khz recommended). *8. sense pin current limiting detection pin. when the pin voltage exceeds 0.2v, the current is limited and the operation enters the lower regeneration mode. connect this pin to gnd when it is not to be used. *9. fg pin rotation speed detection pin. this is an open collector output, which can detect th e rotation speed from the fg output according to the phase changeover. keep this pin open when it is not to be used. *10. ct pin pin to connect the lock detection capacitor. the constant-current charge and discharge circuits incorporated cause locking when the pin voltage becomes 3.0v and unlocking when it is 1.1v. connect the pin to gnd when it is not to be used (locking not necessary). *11. s-s pin pin to connect the soft-start setting capacitor. connect the capacitor between 5vreg and s-s pin. this pin enables setting of the soft start tim e according to the capac ity of the capacitor. see the timing char. connect the pin to gnd when it is not to be used.
lb11867fv no.a0195-7/9 control timing chart (speed control) (1) minimum speed setting (stop) mode the low-speed fan rotation occurs at th e minimum speed set with the rmi pin. when the minimum speed is not set (rmi pin pulled up to 5vreg), the motor stops. (2) low speed ? high speed pmw control is made by comparing the cpwm oscillation voltage (1.1v ? 3.0v) and vth voltage. both upper and lower output trs are turned on when the vth voltage is low. the upper output tr is turned off when the vth voltage is high, regenerating the coil current in the lower tr. therefore, as the vth voltage decreases, the output on-duty increases, causing increase in th e coil current, raising the motor rotation speed. the rotation speed can be monitored with the fg output. (3) full speed mode the full speed mode becomes effective when the vth voltage is 1.1v or less. (set vth = gnd when the speed control is not to be made.) 0v 3.0v 1.1v cpwm f=30khz (cp=220pf) 0% 100% fg onduty vth voltage rmi voltage minimum speed setting rotation (stop mode) low speed high speed pwm control speed variable full speed
