LB1948MC Motor Driver, Forward/Reverse, Low Saturation Voltage Drive, 12V Overview The LB1948MC is a two-channel low saturation voltage forward/reverse motor www.onsemi.com 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 Supports 12V power supply systems Low saturation voltage: V (sat) = 0.5V (typical) at I = 400mA O O Zero current drawn in standby mode Braking function Supports parallel connection: I max = 1.6A, V (sat) = 0.6V (typical) at O O MFP10SK (225mil) I = 800mA O Built-in spark killer diode Built-in thermal shutdown circuit GENERIC Miniature package: MFP10SK (6.4mm 5.0mm) MARKING DIAGRAM* Typical Applications Refrigerator XXXXXXXX Thermal printers YMDDD POS terminal Hot-water supplies Time Recorder XXXX = Specific Device Code Y = Year M = Month DDD = Additional Traceability Data ORDERING INFORMATION Ordering Code: LB1948MC-AH (MSL3) LB1948MC-BH (MSL1) Package MFP10SK (Pb-Free / Halogen Free) Shipping (Qty / packing) 1000 / Tape & Reel For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D.
