SAA1042 Stepper Motor Driver, DIP16
The SAA1042 drives a two–phase stepper motor in the bipolar mode. The device contains three input stages, a logic section and two output stages. The IC is contained in a 16 pin dual–in–line heat tab plastic package for improved heatsinking capability. The center four ground pins are connected to the copper alloy heat tab and improve thermal conduction from the die to the circuit board.
• Drive Stages Designed for Motors: 6.0 V and 12 V: SAA1042V
• 500 mA/Coil Drive Capability
• Built–In Clamp Diodes for Overvoltage Suppression
• Wide Logic Supply Voltage Range
• Accepts Commands for CW/CCW and Half/Full Step Operation
• Inputs Compatible with Popular Logic Families: MOS, TTL, DTL
• Set Input Defined Output State
• Drive Stage Bias Adaptable to Motor Power Dissipation for
Optimum Efficiency
