Sanyo LB1833M Specifications
Ordering number:EN3297
Monolithic Digital IC
LB1833M
Low-Saturation Bidirectional Motor Driver
for Low-Voltage Applications
Overview
The LB1833M is a low-saturation stepping motor driver
IC for use in low-voltage applications. It is especially
suited for use in portable equipment such as printer,
FDD, camera.
Features
• Capable of being operated from a low voltage (2.5V
min).
• Low saturation voltage.
(Upper transistor+low transistor residual voltage 1.0V
max at 400mA).
• Through current preventer on-chip.
• Logic power supply and motor power supply are
sepatate.
• On-chip spark killer diodes.
• Possible to increase the internal allowable power
dissipation because the package is compact (MFP16FS) and heat can be radiated easily to the outside.
