Features

  • Low voltage operation (2.5V min.)
  • Low saturation voltage (upper transistor + lower transistor residual voltage; at IO = 500mA, VO(sat) = 0.75V typ.)
  • Low current drain at standby mode (ICCO = 0.1μA typ. or less)
  • Separate logic power supply and motor power supply
  • Brake function
  • Built-in spark killer diodes Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum supply voltage V CC max -0.3 to +10.5 V VS max -0.3 to +10.5 V Output applied voltage V OUT -0.3 to V CC+ VSF V Input applied voltage V IN -0.3 to +10.0 V Ground pin flow-out current I GND 1.0 A Allowable power dissipation Pd max Mounted on a specified board 820 mW Operating temperature Topr -20 to +75 °C Storage temperature Tstg -40 to +125 °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.
