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 VCC max -0.3 to +10.5 V Maximum supply voltage VS max -0.3 to +10.5 V Maximum output voltage VOUT max VS+ VSF V Maximum input voltage VIN 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 Stepping Motor Driver
