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. 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. 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 new introduction or other application different from current conditions on the usage of automotive device, communication device, office equipment, industrial equipment etc. , please consult with us about usage condition (temperature, operation time etc.) 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. LV8121V Overview The LV8121V is a three-phase brushless motor driver that uses a PWM drive technique. The motor speed is controlled by changing the PWM duty that based on an analog voltage input. This motor driver includes an automatic return constraint protection circuit and is optimal for driving fan motors. Features • PWM control based on an analog voltage input (the CTL voltage), synchronous rectification • One Hall-effect sensor FG output • Automatic return constraint protection circuit (ON/OFF=1/15) • Start/Stop switching circuit, Forward/Reverse switching circuit • Current limiter circuit, Low-voltage shutdown protection circuit, Thermal shutdown protection circuit Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit VCC max VCC pin 36 V Supply voltage VG max VG pin 42 V Output current IO max t ≤ 500ms 3.5 A Allowable power dissipation Pd max Mounted on a specified board * 1.7 W Operation temperature Topr -30 to +100 °C Storage temperature Tstg -55 to +150 °C Junction temperature Tj max 150 °C * Specified board : 114.3mm × 76.1mm × 1.6mm, glass epoxy board Caution 1) Absolute maximum ratings represent the values which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.
