LB1836MEVB

LB1836MEVB is a evaluation board for LB1836M bidirectional motor driver IC. It is a 2 channel low voltage, low saturation voltage type bidirectional motor driver IC that is optimal for use as a 2 phase stepping motor driver. 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 LB1836M can directly control a motor from signals from a microcontroller. The LB1836M is ideally suited for the stepping motor, two phase excitation, and 1-2 phase excitation drive. The LB1836M includes a built in thermal shutdown circuit so that IC scorching or burning is prevented in advance, even if the IC outputs are shorted.

• Low voltage operation (2.5Vmin)
• Low saturation voltage (upper transistor + lower transistor residual voltage; 0.40V typ at 400mA)
• Parallel connection (Upper transistor + lower transistor residual voltage; 0.5V typ at 800mA)
• Separate logic power supply and motor power supply
• Brake function
• Spark killer diodes built in
• Thermal shutdown circuit built in
• Compact package
