1 / 19 page Ordering number : ENN7543 13004TN (OT) No. 7543-1/19 Overview 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 Package Dimensions unit: mm 3196A-DIP30SD 3235A-HSOP36 (1.04) 1.78 0.95 0.48 115 30 16 27.0 SANYO: DIP30SD (400 mil) [LB11690] (6.2) 36 1 0.8 17.8 2.7 0.3 0.25 (0.5) 2.0 SANYO: HSOP36 (375 mil) [LB11690H] LB11690, 11690H SANYO Electric Co.,Ltd.
