LB1838M
Monolithic Digital IC
Low-Voltage, Low-Saturation
Bidirectional Motor Driver
Overview
The LB1838M is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications.
The LB1838M is a bipolar stepper-motor driver IC that is ideal for use in printers, cameras and other portable devices.
Functions
• Low voltage operation (2.5V min)
• Low saturation voltage (upper transistor + lower transistor residual voltage: 0.40V at 400mA)
• Built-in through-current prevention circuit
• Separate logic power supply and motor power supply
• Built-in spark killer diodes
• Built-in thermal shutdown circuit
• Compact package: MFP14S
