National Semiconductor LMD18200 Motor control IC Review
Posted: September 16th, 2010 | Author: Tom Scarince | Filed under: Motor Control | Tags: Neat Components, Servo Motor, Stepper Motor |Configuration: Single H-Bridge
Applications: PM DC, Servo, Stepper
Current (continuous): 3 amps
Current (peak): 6 amps
Voltage (max): 60V
Short circuit protection: Yes
Built-in chopper current limitation: No
Interface: Parallel
Datasheet: LMD18200
Thanks to its voltage and current capability, the LMD18200 is suitable for driving small PMDC sevo motors or a medium size stepper motor winding. It incorporates a unique lossless current sense output that can be used by an external circuit for chopper current control. The LMD18245 is a very similar part that adds a 4-bit linear DAC and built-in chopper circuit.
