LB1948M

2004.2.4 Ordering number : ENN7714 www.DataSheet4U.com SANYO Semiconductors DATA SHEET Monolithic Digital IC LB1948M Overview Low saturation voltage drive forward/reverse 12 V motor driver The LB1948M 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. Applications 12V low saturation voltage forward/reverse motor 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: IOmax=1.6A, VO (sat)=0.6V (typical) at IO= 800mA Built-in spark killer diode Thermal shutdown circuit Miniature package: MFP-10S (6.5 × 5.1mm) Specifications Absolute Maximum Ratings at Ta=25°C Parameter Maximum supply voltage Output voltage Input voltage Ground pin source current Allowable power dissipation Operating temperature Storage temperature Symbol VCC max VOUT VIN IGND Pd max1 Pd max2 Topr Tstg Per channel Independent IC Mounted on a circuit board* Conditions Ratings –0.3 to +20 –0.3 to +20 –0.3 to +18 800 350 870 –20 to +85 –40 to +150 Unit V V V mA mW mW °C °C *: On the stipulated circuit board (114.3 × 76.1 × 1.6tmm, glass epoxy) Any and all SANYO products described or contained herein do not have specifications that can...
