1 / 7 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 '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. 92111 SY 20110901-S00001 No.A1978-1/8 LV8162TT Overview The LV8162TT is a driver IC for single-phase fan motors that achieves low-noise operation by using BTL linear output system. As it has a variable speed function in response to the external PWM input signal, it is best suited for driving CPU cooling fans in notebook PCs and other applications that require low power consumption, low noise, and a variable speed function. Functions • Single-phase full-wave operating by BTL output • Speed control available by PWM pin • Hall bias output pin • Built-in lock protection and automatic return circuit • Standby mode and quick start function • Start auxiliary function (50% futy start) • FG (rotation speed detection) signal pin and RD (lock detection) signal pin • Built-in thermal-shutdown (TSD) circuit Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max 7 V Maximum output current IOUT max 0.7 A OUT pin output withstand voltage VOUT max 7 V HB pin maximum output current IHB max 10 mA PWM pin withstand voltage VPWM max 7 V FG/RD pin maximum sink current IFG/IRD max 5 mA FG/RD pin output withstand voltage VFG/VRD max 7 V Allowable dissipation Pd max1 Independent IC 200 mW Pd max2 With specified substrate *1 400 mW Operating temperature Topr *2 -30 to +95 °C Storage temperature Tstg -55 to +150 °C Continued on next page.
