1 / 6 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. 30712 SY 20111213-S00004 No.A2015-1/6 LB1948MC Overview The LB1948MC is a two-channel low saturation voltage forward/reverse motor driver IC. It is optimal for motor drive in 12V system products and can drive either two DC motors, one DC motor using parallel connection, or a two-phase bipolar stepping motor with 1-2 phase excitation mode drive. Features • Supports 12V power supply systems • Low saturation voltage: VO(sat) = 0.5V (typical) at IO = 400mA • Zero current drawn in standby mode • Braking function • Supports parallel connection: IO max = 1.6A, VO(sat) = 0.6V (typical) at IO = 800mA • Built-in spark killer diode • Built-in thermal shutdown circuit • Miniature package: MFP-10S (6.4mm × 5.0mm) Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max -0.3 to +20 V Output voltage VOUT -0.3 to +20 V Input voltage VIN -0.3 to +18 V Ground pin source current IGND Per channel 800 mA Allowable power dissipation Pd max Mounted on a specified board* 870 mW Operating temperature Topr -20 to +85 °C Storage temperature Tstg -40 to +150 °C * Specified board: 114.3mm × 76.1mm × 1.6mm, glass epoxy board. Caution 1) Absolute maximum ratings represent the value 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. Please contact us for the further details. Monolithic Digtal IC 12V Low Saturation Voltage Drive Forward/Reverse Motor Driver Ordering number : ENA2015 |
