Overview
The LB1256 is a 7-unit driver array, possessing high-current, low-saturating outputs. It has a motor driver circuit
equipped with a brake circuit. It is suited for low-voltage,
high-current driver use.
Features
• Has a large current capacity (400mA) and low saturation
voltage (0.5V max).
• Has a motor driver with a spark suppressor.
• Ideal for various battery-operated preinter drivers.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer's
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer's products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
