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.
Package Dimensions
unit:mm 3097-MFP16FS
[LB1833M]
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.

Sample Application Circuit
Note : Use one of the FRAME-GND pins for grounding. when the Cufoild side is soldered, heat radiation can be more improved.
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 give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
