1 / 5 page Specifications of any and all SANYO Semiconductor Co.,Ltd. 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 'sproductsor equipment. Any and all SANYO Semiconductor Co.,Ltd. products described or contained herein are, with regard to "standard application", intended for the use as general electronics equipment (home appliances, AV equipment, communication device, office equipment, industrial equipment etc.). The products mentioned herein shall not be intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee thereof. If you should intend to use our products for applications outside the standard applications of our customer who is considering such use and/or outside the scope of our intended standard applications, please consult with us prior to the intended use. If there is no consultation or inquiry before the intended use, our customer shall be solely responsible for the use. 31109 MS 20080221-S00008 / 83100RM(KI) No.6204-1/5 LB1867M Overview The LB1867M is a 2-phase unipolar brushless motor driver. With only a few peripheral parts, lockup protection and automatic recovery can be implemented. The IC can be configured for 12V or 24V operation and a wide range of variations, from Low speed to H-High speed and from 60cm to 120cm square using the same PCB. This makes it easy to design highly reliable fan motor installations. Features • Output protection Zener diode with variable withstand voltage Z1, Z2 pins open: VOLM = 57V (24V specification) Z1, Z2 pins shorted: VOLM = 32V (12V specification) External Zener diode connected across Z1 − VCC pins: support for fans with large drive current • External resistor allows configuration for 12V or 24V • Direct Hall element connection possible (built-in Hall amplifier with hysteresis supports core without auxiliary electrode) • Built-in output transistor with 1.0A output current (strengthened negative-current support for core without auxiliary electrode) • Built-in rotation detection function: Low during rotation and High during stop • Built-in lockup protection with automatic recovery • Built-in thermal shutdown Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum input current ICC max t ≤ 20ms 200 mA Maximum applied output voltage VOUT max Internal V Maximum output current IOUT max 1.0 A Maximum current flowing into RD pin IRD max 10 mA Maximum RD applied voltage VRD max 30 V Allowable power dissipation Pd max Mounted on a specified board * 800 mW Operating temperature Topr -30 to +80 °C Storage temperature Tstg -55 to +150 °C * Specified board: 20mm × 15mm × 1.5mm, glass epoxy board.
