SiLM9409 - Forward/Reverse Low Saturation Voltage Motor Driver

General Description

The SiLM9409 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 = 0.9 Ω Typ. ).
  • VCC (Max) = 26V, IO (Max) = 1.2A, IO (RMS) = 0.8A.
  • 5V to 26V operating supply voltage range (The control system power supply is unnecessary. ).
  • The compact package (SSOP10) is adopted.

SiLM9409 Motor Driver, Forward/Reverse, Low Saturation Voltage GENERAL DESCRIPTION The SiLM9409 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 Hbridge of the SiLM9409 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. The SiLM9409 is available in a compact SSOP10 package.
