Description
Ordering number : EN5686 Monolithic Digital IC LB1821M Power Brushless Motor Pre-Driver IC for OA Equipment Overview The LB1821M is a pre-driver IC.
Features
* Direct PWM drive output Speed discriminator + PLL speed control circuit FG and integrating amplifiers Forward/reverse switching circuit Braking circuit (short braking) Speed lock detection output Full complement of on-chip protectApplications
* can handle a wider range of speed variations than would be possible if a fixed number of counts was used by changing the number of discriminator counts (which is related to the divisor in the VCO circuit). The number of counts can be switched between 64, 128, 256, and 512 by setting the N1 (pin 10)LB1821M Distributors
