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.
