LB1948MC: Motor Driver, Forward / Reverse, Low Saturation Voltage, 12 V

The LB1948MC is a two-channel low saturation voltage forward/reverse motor driver IC. It is optimal for motor drive in 12V system products and can drive either two DC motors, one DC motor using parallel connection, or a two-phase bipolar stepping motor with 1-2 phase excitation mode drive.

Features
  • 20 V max operating voltage
  • Zero current drawn in standby mode
  • Braking function
  • Built-in spark killer diode
  • Built-in thermal shutdown circuit
  • Miniature package: MFP-10SK (6.2mm 5.0mm)
  • Low saturation voltage: VO(sat) = 0.5V (typical) at IO = 400mA
  • Supports parallel connection: IO max = 1.6A, VO(sat) = 0.6V (typical) at IO = 800mA
Benefits
  • Good safety margin for driving 12V motors
  • Saving energy
  • Safety design
  • Spark killer
  • Thermal protection
  • Small mounting space
