Technical content

Features

  • Low saturation voltage forward/reverse motor driver (VO sat = 0.25V at IO = 200mA)
  • Two H-bridge channels
  • Wide usable voltage range (Allowable voltage range : 2.5V to 9.5V, absolute maximum rating : 10.5V)
  • Supports PWM input (Low power consumption can be achieved in slow delay mode that uses IN1/IN2 = H/H logic.)
  • Motor (coil) current detection pin
  • Built-in thermal shutdown circuit
  • Miniature package (SSOP16 : 225mil) 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 Maximum output voltage V OUT max VS+ VSF V Maximum input voltage V IN max -0.3 to +8.0 V Ground pin source current IGND max Per channel 800 mA Allowable power dissipation Pd max When mounted on a circuit board * 740 mW Operating temperature Topr -20 to +85 °C Storage temperature Tstg -40 to +150 °C * Specified circuit board : 114.3 × 76.1 × 1.6mm3, glass epoxy Monolithic Digital IC 1-2 Phase Excitation Stepper 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.
