Ordering number:ENN1482C
Monolithic Digital IC
LB1249
Active-Low Input, 8-Unit, High-Current,
Low-Saturation Driver
Applications
• 4-phase stepping motor driver of 2 channels.
• Especially suited for X-Y axis plotter printer driver.
• High current, low saturation voltage general-purpose 8-
unit driver (relay, LED, lamp solenoid, etc.).
Features
• Low active input type.
• On-chip input protecting diodes.
• High current capacity (400mA) and low saturation volt-
age (0.5V max).
• On-chip spark killer diodes.
• Wide duty due to Pd of 3W max.
