LB1843V

Ordering number: EN 4385B Monolithic Digital IC LB1843V 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. Package Dimensions unit : mm 3179A-SSOP20 [LB1843V] Features . Output current limiter and detector built in . Low-saturation voltage bidirectional bridge circuit built in: sat = 0.40 V typ. at 400 mA .V 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 O needed and the IC is contained in a small SSOP-20 package SANYO : SSOP20 Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply voltage Maximum output current Applied input voltage Allowable power dissipation Operating temperature Storage temperature Symbol VCC max Im max VIN Pd max Topr Tstg With board ( 50 × 35 × 1.6 mm ) 3 Conditions Ratings 10.5 800 –0.3 to +10 800 –20 to +80 –40 to +150 Unit V mA V mW °C °C Allowable Operating Ranges at Ta = 25°C Parameter Supply voltage VM voltage High-level input voltage Low-level input voltage LIR input voltage Output current limitation Symbol VCC VM VIH VIL VLIR Ilimit Conditions Ratings 3.0 to 9.0 2.2 to VCC 3.0 to 9.0 –0.3 to +0.7 0.5 to VCC–1.0 50 to 350 Unit V V V V V mA SANYO Electric ...
