LB1838M: Motor Driver, Low Saturation, Bidirectional, for Low Voltage Drive
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.
特性- Low voltage and wide 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
