Stepper motor driver

29 April 2015 Power Electronics / Power Management

The new LV8714TA from ON Semiconductor is a highly energy efficient, dual stepper motor driver with operating voltages ranging from 4 V to 16,5 V. Featuring constant current control for its on-chip quad H-bridge channels, it is capable of driving two stepper or four DC motors independently. The device’s power FETs with total on-state resistance of only 0,9 Ω for one leg and synchronous rectification type switching allow its power consumption to be kept to a minimum while in full operation. It has a power saving mode with < 1 μA standby current and an internal current sense mechanism that ensures lossless current measurement without any external power resistor. On-chip regulators enable single supply operation of the device.
