The thermal protection circuit is implemented to prevent the IC from being thermally damaged or burned when exposed to an environment exceeding the guaranteed operating temperature range. Thermal design must be carried out so that the thermal protection circuit will never be activated while the fan is running in a stable condition. Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the Electrical Characteristics if operated under different conditions. www.onsemi.com 3 LB11660RV Package Dimensions unit : mm SSOP16 (225mil) CASE 565AM ISSUE A to GENERIC MARKING DIAGRAM* SOLDERING FOOTPRINT* 5.80 1.0 (Unit: mm) 0.32 XXXXXXXXXX YMDDD XXXXX = Specific Device Code Y = Year M = Month DDD = Additional Traceability Data 0.65 NOTE: The measurements are not to guarantee but for reference only. *For additional information on our Pb-Free strategy and soldering details, please download the ON Semiconductor Soldering and Mounting Techniques Reference Manual, SOLDERRM/D. www.onsemi.com 4 *This information is generic.

Since the current of a current limiter circuit is limited by the current determined by IO = VRf/Rf (where VRf = 0.5V typ, Rf: current-sensing resistance), the current limiter is actuated at IO = 1A when Rf = 0.5. The Rf resistor must be connected without fail, and its constant must be within the recommended operating range for current limiters. www.onsemi.com 6 LB11660RV *5 Wiring need to be short to prevent carrying of the noise. The Hall input circuit is a comparator having a hysteresis of 20mV. It is recommended that the Hall input level be more than three times (60mVp-p) this hysteresis. *6 < PWM oscillation frequency setting capacitor > The oscillation frequency is 23kHz when CP = 200pF and 46kHz when CP = 100pF, and this serves as the PWM fundamental frequency. For the most part, the PWM frequency can be obtained from the following formula: f [kHz]  (4.6106) ÷C [pF] *7 This is the open collector type output, which outputs ''L'' during rotation. It is set to 'OFF' when a lock is detected. This output is left open when not in use. *8 This is a Hall element bias pin, that is, the 1.25V constant-voltage output pin. *9 Lowest speed setting pin for speed control. The minimum output duty setting is made with R3 and R4. The R4 is left open to stop operation at a duty ratio of 0%.
