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

*1 When the diode Di is used to prevent device destruction from reverse connection, the capacitor Cr must be inserted to
assure a path for regenerative currents.
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.
