1 / 6 page Low-saturation, current-controlled bidirectional motor driver Overview The LB1843V is a low-saturation bidirectional motor driver with output current limitation and detection functions. This design is ideal for controlling the loading motor in a video camera. Features . Output current limiter and detector built in . Low-saturation voltage bidirectional bridge circuit built in: VOsat = 0.40 V typ. at 400 mA . Practically no current drain (0.1 µA or less) in standby mode . Input-linked reference voltage built in . Thermal shutdown circuit built in . Requires little space, since few external components are needed and the IC is contained in a small SSOP-20 package Package Dimensions unit : mm 3179A-SSOP20 [LB1843V] SANYO : SSOP20 Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum supply voltage VCC max 10.5 V Maximum output current Im max 800 mA Applied input voltage VIN –0.3 to +10 V Allowable power dissipation Pd max With board ( 50 × 35 × 1.6 mm3 ) 800 mW Operating temperature Topr –20 to +80 °C Storage temperature Tstg –40 to +150 °C Allowable Operating Ranges at Ta = 25°C Parameter Symbol Conditions Ratings Unit Supply voltage VCC 3.0 to 9.0 V VM voltage VM 2.2 to VCC V High-level input voltage VIH 3.0 to 9.0 V Low-level input voltage VIL –0.3 to +0.7 V LIR input voltage VLIR 0.5 to VCC–1.0 V Output current limitation Ilimit 50 to 350 mA Ordering number: EN 4385B Monolithic Digital IC LB1843V SANYO Electric Co.,Ltd.
