L6480HTR STMicroelectronics 0.004 kW DC Motor Controller, 95 V, 2 Phase, Current Controller Function, 85 V

The STMicroelectronics L6480 device, realized in analog mixed signal technology, is an advanced fully integrated solution suitable for driving two-phase bipolar stepper motors with micro stepping. It integrates a dual full bridge gate driver for N-channel MOSFET power stages with embedded non dissipative overcurrent protection. Thanks to a unique voltage mode driving mode which compensates for BEMF, bus voltage and motor winding variations, the micro stepping of a true 1/128-step resolution is achieved. The digital control core can generate user defined motion profiles with acceleration, deceleration, speed or target position easily programmed through a dedicated register set._x000D_ Operating voltage: 7.5 V - 85 V_x000D_ Dual full bridge gate driver for N-channel MOSFETs_x000D_ Fully programmable gate driving_x000D_ Embedded Miller clamp function_x000D_ Programmable speed profile_x000D_ Up to 1/128 micro stepping
