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 VCC max -0.3 to +10.5 V Maximum supply voltage 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. Please contact us for the further details. Monolithic Digital IC Low-Voltage, Low-Saturation Bidirectional Motor Driver Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Oper ating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
