Sales Briefcase
  • The L99SM81V is an automotive grade integrated driver for bipolar two-phase stepper motors capable of current controlled micro-stepping with programmable amplitude. The device features a 5 V voltage regulator to supply external sensors.

    The integrated Serial Peripheral Interface (SPI) makes it possible to adjust device parameters, control all operating modes and read out diagnostic information. Digital I/Os are also optionally usable for more flexible and reliable application control.

    主要特性

    • AEC-Q100 qualified
    • Stepper motor driver with up to 1.35 A current capability
    • Programmable stepping mode:
      • Full step, Half step, Mini step, 1/8 Micro step, 1/16 Micro step
    • Current regulation by integrated PWM control with fully integrated current sensing
    • Equivalent 10 bit resolution on current regulation loop:
      • Two 4-bit programmable full scale current amplitudes: one for RUN and one for HOLD mode
      • 6-bit DAC for reference current generation (whatever programmed full scale amplitude)
    • 4 programmable decay modes:
      • Slow-mode, mixed-mode and 2x automatically selected decay-modes
    • 3x programmable inputs for direct control of step clock, direction, hold and step modes
    • 1x programmable analog output for Tj measurement or band-gap reference
    • 2x programmable digital outputs for internally generated PWM ON duty cycles, error signals, coils voltage measurement synchronization signals
    • Programmable MOSFETs switching speed: four options for EMC and power dissipation trade-off optimization
    • PWM frequency wobbling for reduction of conducted EM energy
    • Outputs protection and diagnosis (open load, short to battery, short to GND)
    • Integrated ADC for coil voltage measurement and stall detection
    • 5 V low drop voltage regulator short-circuit protected
    • Very low current consumption in standby mode (typ. 10 µA)
    • Thermal warning and shutdown
    • ST SPI 4.0 interface for control and diagnostics
