LB1948MC

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.
