LV8064TT Overview
Ordering number : ENA1525 .. Bi-CMOS IC LV8064TT Overview Fan Motor Driver Single-Phase Full-Wave Driver 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 Specifications
