Overview

Ordering number : ENA0287 LB11693H Monolithic Digital IC 3-Phase Brushless Motor Driver for 24V Fan Motors http://onsemi.
com Overview The LB11693H 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 24V fan motors.
Functions • 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 circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Supply voltage range Output current Allowable power dissipation 1 VCC max IO max Pd max1 T ≤ 500mS Independent IC Allowable power dissipation 2 Pd ...
