LB11948T Datasheet Monolithic Digital Ic Pwm Constant Current Control 1-2 Phase Excitation Stepping Motor Driver

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : ENN7947A Monolithic Digital IC LB11948T .. PWM Constant Current Control 1-2 Phase Excitation Stepping Motor Driver Overview The LB11948T is a low saturation voltage output PWM current control bipolar drive stepping motor driver. It is optimal for use as the driver for the miniature low-voltage stepping motors used in portable electronic equipment such as portable thermal printers.

Key Features

  • PWM current control (external excitation).
  • Simultaneous on state prevention function (through current prevention).
  • Thermal shutdown circuit.
  • Noise canceller function.
  • Low-power mode control pin Specifications Maximum Ratings at Ta = 25°C Parameter VS supply voltage Logic system supply voltage Peak output current Continuous output current Emitter output voltage Input voltage Allowable power dissipation Operating temperature Storage temperature Note ∗.
