LB11690
The LB11690 and LB11690H 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.
Functions and Features
• Three-phase bipolar PWM drive (high and low side
n-channel FET drive)
• Maximum supply voltage: 45 V
• Gate drive voltage: about 10 V (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作者: 南京驰邦科技 时间: 2005-5-23 10:32 标题: 电动车无刷电机控制用LB11690 SANYO原装LB11690，我有现货，需要请来电询价，量大优惠，刘先生，13813890958。
