LB11876

Ordering number : EN8317 www.datasheet4u.com Monolithic Digital IC LB11876 Overview For Polygonal Mirror Motors Three-Phase Brushless Motor Driver The LB11876 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor in plain-paper copiers and similar products. It can support any motor voltage and motor current required by the use of appropriate external components. The LB11876 adopts direct PWM drive to achieve drive with minimal power loss. Functions This is a version of the LB11875 with a modified constraint protection function. Three-phase bipolar drive (direct PWM) PLL speed control circuit Dedicated external clock Clock divider switching function Hall sensor FG support Short-circuit braking function Built-in current limiter, thermal protection, constraint protection, and undervoltage protection circuits Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage Input current Output current LVSD pin apply voltage Symbol VCC max I13 max IO max LVSD max V13 pin UL pin, VL pin, WL pin, UH pin, VH pin, and WH pin Conditions Ratings 18 5 30 Unit V mA mA V 18 Continued on next page.
