LB1851M

The LB1851M is a 3-phase brushless motor driver 1C ideally suited for use in VCR capstan motor driver,drum motor driver, and DAT motor driver applications.No products described or contained herein are intended for use in surgical implants, life-support systems,aerospace equipment,nuclear power control systems, vehicles, disaster/crime-prevention equipment and the like, the failure of which may directly or indirectly pause injury, death or property loss.

Features of the LB1851M are:(1)120 voltage linear type; (2)less power dissipation because of speed control based on motor voltage control(suitable for use in portable sets); (3)torque ripple compensation circuit on chip; (4)small capacitance of external capacitor because of soft switching method (chip capacitor); (5)Thermal shutdown circuit on chip; (6)FG amp on chip.

The absolute maximum ratings of the LB1851M can be summarized as:(1)maximum supply voltage1:7V;(2)storage temperature:-55 to 125;(3)operating temperature:-20 to 75;(4)output current:1.5A;(5)allowable power dissipation:1.0 W.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics. Before ordering, purchasers are advised to contact the Sensitron Semiconductor sales department for the latest version of the datasheet(s).In cases where extremely high reliability is required (such as use in nuclear power control, aerospace and aviation, traffic equipment,medical equipment, and safety equipment), safety should be ensured by using semiconductor devices that feature assured safety or by means of users' fail-safe precautions or other arrangement.In no event shall Sensitron Semiconductor be liable for any damages that may result from an accident or any other cause during operation of the user's units according to the datasheet(s).
