Ordering number : ENA2062 LV8063FA Bi-CMOS IC Fan Motor Driver http://onsemi.com Single-Phase Full-Wave Driver Overview The LV8063FA is the driver IC with BTL linear output for single-phase fan motor, and that drives at high efficiency, low power, and low noise by suppressing the reactive power. The BTL output can be combined with the PWM control by an external signal, which is optimum for the note PC, the CPU cooler, etc. that requires low power dissipation and low noise. Functions • Single-phase full-wave operating by BTL output (BTL amplifier gain : +43dB) • Speed control available by PWM pin • Hall bias output pin (VHB = 1.05V typ) • Built-in Quick Start circuit • FG(rotation signal) output pin (Open drain output) • Built-in thermal-shutdown (TSD) circuit • Built-in lock protection and automatic return circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max OUT pin output current IOUT max1 In regular mode IOUT max2 In lock-detection mode 1 A OUT pin output voltage handling VOUT max 7 V FG output voltage handling VFG max 7 V FG output current IFG max 5 mA HB output current IHB max 10 mA Allowable power dissipation 7 V 0.7 A Pd max1 Independent IC 0.2 W Pd max2 IC on board * 0.4 W Operating temperature Topr -30 to +95 °C Storage temperature Tstg -55 to +150 °C * Specified substrate : 20mm × 10mm × 0.8mm, Paper phenol Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

Similarly, if there no nearby capacitors on the fan power supply line, the capacitor Cr is also required to increase reliability. *2 The Hall element is biased at a constant voltage of approximately 1.05Vfrom the HB pin. Thus LV8063TT provides a stable Hall output with excellent temperature characteristics. If the Hall output is needed to adjust the amplitude, use the resistor R1 as shown in the figure. *3 When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure. *4 This pin must be left open if unused. *5 When a PWM signal seems to be the open collector (a drain) output, please connect suitable pulling up resistance so that a H/L level is decided.
