1 / 5 page 31110 SY / 91207 MS PC 20070831-S00003 No.A0927-1/5 http://onsemi.com Semiconductor Components Industries, LLC, 2013 June, 2013 LB1838JM Overview The LB1838JM is a low-saturation two-channel bidirectional motor driver IC for use in low-voltage applications. It has a wide operating temperature range of -40 to 80 °C and is ideal for 2-phase excitation bipolar stepping motor driver IC used in automotive components (other than critical safety parts), consumer and industrial products, and many other applications. Features • Low voltage operation (2.5V min) • Low saturation voltage (upper transistor + lower transistor residual voltage ; 0.40V typ at 400mA). • Through-current prevention circuit built in • Separate logic power supply and motor power supply • Spark killer diodes built in • Thermal shutdown circuit built in • Compact package (14-pin MFP) Specifications Absolute Maximum Ratings at Ta = 25 °C Parameter Symbol Conditions Ratings Unit VCC max -0.3 to +10.5 V Maximum supply voltage VS max -0.3 to +10.5 V Output supply voltage VOUT VS to VSF V Input supply voltage VIN -0.3 to +10 V GND pin flow-out current IGND Per channel 1.0 A Pd max1 Independent IC 550 mW Allowable power dissipation Pd max2 * Mounted on a board. 800 mW Operating temperature Topr -40 to +85 °C Storage temperature Tstg -55 to +150 °C * Mounted on a substrate : 30 ×30×1.5mm 3, glass epoxy board. Monolithic Digital IC Low-Saturation Bidirectional Motor Driver for Low-Voltage Drive Ordering number : ENA0927A Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. |
