SiLM9409
SiLM9409 is Forward/Reverse Low Saturation Voltage Motor Driver manufactured by Sillumin.
DESCRIPTION
The Si LM9409 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 Si LM9409 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 Si LM9409 is available in a pact SSOP10 package.
