LV8161MU
Monolithic Linear IC
Single-Phase Fan Motor Driver
Overview
http://onsemi.com
LV8161MU is the driver IC with BTL linear output for single-phase fan motor, and that drives at low noise by
suppressing the reactive power. Moreover, it has the function to fix to the rotational speed corresponding to
the oscillatory frequency set with CIN/COUT pins, and that speed control is done by PWM. So, the output
signal forms BTL combined with PWM.
It is optimum for the small fan motor that requires low power dissipation, low noise, and the fixed rotational
speed.
Function
•
Single-phase full wave operating by BTL output
(BTL amplifier gain: +45.5dB)
•
The fixed rotational speed function
(possible to adjust the speed by the value of resistor
and capacitor connected to CIN/COUT pins)
•
Hall bias output pin (VHB = 1.03V (typ))
•
FG (rotation signal) output pin (Open drain output)
•
Built-in motor start-up assistance function
(PWM with 100% duty in output at start-up)
•
Built-in lock protection and automatic restart circuit
•
Built-in thermal-shutdown (TSD) circuit
