Ordering number : ENA1913A LB11620GP Monolithic Digital IC Brushless Motor Driver Overview The LB11620GP is a direct PWM drive pre-driver IC that is optimal for three-phase power brushless motors. A motor driver circuit with the desired output capability (voltage and current) can be implemented by adding discrete transistors or other power devices to the outputs of this IC. Since the LB11620GP is provided in a miniature package, it is also appropriate for use with miniature motors as well. Features • Three-phase bipolar drive • Direct PWM drive (input of either a control voltage or a variable-duty PWM signal) • Built-in forward/reverse switching circuit • 5V regulator output (VREG pin) • Built-in current limiter circuit (0.25V (typical) reference voltage) • Built-in under voltage protection circuit • Built-in automatic recovery type constraint protection circuit (ON: OFF=1: 18) with protection operating state discrimination output (RD pin) • Hall signal pulse outputs Specifications Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Supply voltage 1 VCC max VCC pin Output current IO max Allowable power dissipation Pd max Operating temperature Storage temperature Ratings Unit 18 V UL, VL, WL, UH, VH, WH pins 30 mA *Mounted on a circuit board. 1.0 W Topr -30 to +100 °C Tstg -55 to +150 °C * Mounted on a circuit board: 40.0mm×50.0mm×0.8mm, glass epoxy board.
