LB1838MEVB

LB1838MEVB is a evaluation board for LB1838M bidirectional motor driver IC. 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. 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. The LB1838M is ideally suited for the stepping motor, two phase excitation, and 1-2 phase excitation drive. The LB1838M 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 at 400mA)
• Built in through current prevention circuit
• Built in spark killer diodes
• Built in thermal shutdown circuit
• Compact package
