LV8064TT
Bi-CMOS IC
Fan Motor Driver
Single-Phase Full-Wave Driver
Overview
The LV8064TT is a single-phase bipolar fan motor driver IC. It features quiet operation that suppresses reactive current
through BTL output system. The speed control range can be adjusted to desired values by the external application program,
so that it can rotate fan at lower speeds than conventional drivers in the same driver voltage control range. It is optimal for
use in applications that require low noise and power saving, including CPU coolers.
Functions
• Single-phase full-wave drive with BTL output (BTL amplifier gain = 43dB)
• Speed control gain adjusted by SET pin
• Constant-voltage output pin for Hall bias (VREG = 1.05V typ)
• FG output pin (open collector output)
• Lock protection and auto return circuits built-in
• Built-in thermal protection circuit
