LV8064TT

Ordering number : ENA1525 www.DataSheet4U.com 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 Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output current Symbol VCC max IOUT max1 IOUT max2 Output withstand voltage FG output withstand FG output current REG output current Allowable dissipation VOUT max VFG max IFG max IREG max Pd max1 Pd max2 Junction temperature Operating temperature Storage temperature Tj max Topr Tstg Independent IC With specified substrate * During steady state During lock protection Conditions Ratings 7 0.7 1 7 7 5 10 0.2 0.4 +150 -30 to +95 -55 to +150 Unit V A A V V mA mA W W °C °C °C * Specified substrate : 20mm × 10mm × 0.8m...
