LV8063TT

Ordering number : ENA1850 Bi-CMOS IC LV8063TT Overview Fan Motor Driver Single-Phase Full-Wave Driver The LV8063TT 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 Maximum supply voltage OUT pin output current Symbol VCC max IOUT max1 IOUT max2 OUT pin output voltage handling FG output voltage handling FG output current HB output current Allowable power dissipation VOUT max VFG max IFG max IHB max Pd max1 Pd max2 Operating temperature Storage temperature Topr Tstg Independent IC IC on board * In regular mode In lock-detection mode Conditions Ratings 7 0.7 1 7 7 5 10 0.2 0.4 -30 to +95 -55 to +150 Unit V A A V V mA mA W W °C °C * Specified substrate : 20mm × 10mm × 0.8mm, Paper phenol Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.).

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.
