LB11693

Ordering number : ENN8095 www.DataSheet4U.com SANYO Semiconductors DATA SHEET Monolithic Digital IC LB11693 Overview Three-Phase Brushless Motor Driver for 24 V Fan Motors The LB11693 reduces motor noise by imparting a slope to the output current when switching the phase to which power is applied. This motor driver includes an automatic recovery constraint protection circuit and is optimal for driving 24 V fan motors. Functions and Features Soft phase switching + direct PWM drive PWM control based on both a DC voltage input (the CTL voltage) and a pulse input Provides a 5 V regulator output One Hall-effect sensor FG output Integrating amplifier Automatic recovery constraint protection circuit (on/off = 1/14), RD output Current limiter circuit LVSD circuit Thermal protection circuitt Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Output current Allowable power dissipation 1 Allowable power dissipation 2 Operating temperature Storage temperature Symbol VCC max IO max Pd max1 Pd max2 Topr Tstg T ≤ 500 ms Independent IC With an infinite heat sink Conditions Ratings 30 1.8 3 20 –30 to +100 –55 to +150 Unit V A W W °C °C Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious phys...
