Overview
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
• Supports 12V power supply systems
• Low saturation voltage: VO(sat) = 0.5V (typical) at IO = 400mA
• Zero current drawn in standby mode
• Braking function
• Supports parallel connection: IO max = 1.6A, VO(sat) = 0.6V (typical) at IO = 800mA
• Built-in spark killer diode
• Built-in thermal shutdown circuit
• Miniature package: MFP-10S (6.4mm × 5.0mm)

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time.
Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
