SLM1909 - Motor Driver

General Description

The SLM1909 is a 2-channel low saturation voltage forward/reverse motor driver IC.

It is optimal for motor drive in 12V and 24V system products and can drive a stepper motor in Full-step.

Key Features

  • DMOS output transistor adoption (upper and lower total Rdson = 0.65 Ω Typ. ).
  • VCC Max = 28V, IO Max = 1.2A, IO RMS = 0.8A.
  • 4V to 28V operating supply voltage range (The control system power supply is unnecessary. ).
  • The compact package (SOIC-10) is adopted.
  • Current consumption 0 when standby mode.

Motor Driver, Forward/Reverse, Low Saturation Voltage, 28V SLM1909 GENERAL DESCRIPTION The SLM1909 is a 2-channel low saturation voltage forward/reverse motor driver IC. It is optimal for motor drive in 12V and 24V system products and can drive a stepper motor in Full-step. Each H-bridge output consists of a pair of N-channel and P-channel MOSFETs, with circuitry that regulates the winding current. With proper PCB design, each H-bridge of the SLM1909 can drive up to 0.8A RMS continuously at 25°C. The device can support peak currents of up to 1.2A per bridge. Internal shutdown functions are provided for undervoltage lockout, and over temperature. A low-power sleep mode is also provided. The SLM1909 is available in a compact SOIC-10 package.
