ON Semiconductor LB1838MEVB Bidirectional Motor Driver IC Evaluation Board Stepper Evaluation Board for LB1838M-TRM-E

The LB1838M is 2-channel low-voltage, low saturation voltage type bidirectional motor driver IC that is optimal for use as 2-phase stepping motor driver in printers, floppy disk drives, and cameras and other portable equipment. The output circuits are of the bipolar type, with pnp transistors in the upper side and npn transistors in the lower side, and they achieve low saturation output and low power characteristics despite being provided in a miniature package. The LB1838M can directly control a motor from signals from a microcontroller.

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
Built-in spark killer diodes
Built-in thermal shutdown circuit
Compact package: MFP14S
