产品概述

The LMD18245T/NOPB is a 3A 55V DMOS Full-bridge Motor Driver incorporates all the circuit blocks required to drive and control current in a brushed type DC motor or one phase of a bipolar stepper motor. The multi-technology process used to build the device combines bipolar and CMOS control and protection circuitry with DMOS power switches on the same monolithic structure. It controls the motor current via a fixed off-time chopper technique. An all DMOS H-bridge power stage delivers continuous output currents up to 3A (6A peak) at supply voltages up to 55V. The DMOS power switches feature low RDS(ON) for high efficiency and a diode intrinsic to the DMOS body structure eliminates the discrete diodes typically required to clamp bipolar power stages. An innovative current sensing method eliminates the power loss associated with a sense resistor in series with the motor.
  • Internal clamp diodes
  • Low-loss current sensing method
  • Digital or analog control of motor current
  • TTL and CMOS compatible inputs
  • Thermal shutdown (outputs off) at TJ = 155°C
  • Over-current protection
  • No shoot-through currents
  • Green product and no Sb/Br

应用

工业, 医用, 电机驱动与控制

警告

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
