The LV8714TA is an extremely energy efficient dual stepper motor driver with operating voltage range from 4 V to 16.5 V. With low on resistance type power FETs, loss-less current sensing, synchronous rectification, and ultra-low standby current (<1µA), the device offers the best-in-class energy efficient system solution. Integrated regulators enable one-chip, single supply system solution. Built-in system protection functions such as over-current, thermal shutdown and low voltage shutdown enable a highly reliable system solution with smallest system solution footprint. Among wide variety of applications that the LV8714TA addresses are security camera systems, point of sale (PoS) terminals, document scanners and multi-function printers.
Features   Benefits
  • Quad H-bridges with PWM based constant-current control
  • One-chip solution that drives dual stepper or quad DC motors
  • Power FETs with low on resistance (Upper: 0.6Ω, Lower: 0.3Ω, Total of upper and lower: 0.9Ω @ Ta=25°C, Io=1.5A)
  • Minimizes power loss while in operation
  • Internal current sense mechanism without external power resistors
  • Loss-less current sensing that enhances energy efficiency
  • On-chip regulators for logic circuits and power FETs biasing
  • Single supply operation without external component
  • Power saving mode with ultra-low standby current (< 1µA) when idle
  • Enhances energy efficiency of the system solution
  • Built-in system protection functions such as thermal shutdown, low-voltage shutdown and over-current protection
  • Reliable system solution under harsh operating conditions
  • Full, Half, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128, 1/256 and over microstep drive is realizable by controlling VREF voltage
  • High convenience by abundant excitation mode, and low vibration by high resolution
