LB11691 Datasheet Monolithic Digital Ic Pre-driver Ic

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : ENA0879 www.DataSheet4U.com LB11691 Overview Monolithic digital IC Pre-Driver IC for Brushless Motor Drive in Electric Bicycles The LB11691 are three-phase bipolar PWM drive pre-driver ICs that allow the output circuits to be implemented using only n-channel FETs. These ICs can implement, at low cost, high-efficiency drive circuits in applications that use motors that require high drive currents. These ICs include a built-in Hall sensor signal F/V conversion circuit and can provide a voltage that is proportional to motor speed for use, for example, in speedometers for electric bicycles. These ICs also support use in applications that holds the speed controlled at a constant rate as the load varies.

Key Features

  • Three-phase bipolar PWM drive (high and low side n-channel FET drive).
  • Maximum supply voltage : 45V.
  • Gate drive voltage : about 10V (high and low side n-channel FETs).
  • Hall sensor signal F/V conversion circuit (one-shot multivibrator output).
  • Synthesized three-phase Hall sensor signal output.
  • Built-in current limiter and undervoltage protection circuits Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Supply voltage 1 Supply v.
