Frequently Asked Questions
What is the maximum supply voltage for the LMD18245T/NOPB?
The LMD18245T/NOPB supports a motor supply voltage (VM) up to 55V, making it suitable for industrial 24V and 48V bus architectures. It can deliver up to 3A continuous and 6A peak output current, giving designers headroom for high-torque startup conditions.
How does the LMD18245 control motor speed and direction?
The LMD18245 uses a full H-bridge topology controlled via PWM input signals. Direction is set by logic-level DIR pins while a PWM signal on the PHASE/ENABLE input regulates motor speed. An internal charge pump ensures proper high-side gate drive without an external bootstrap circuit.
What does the NOPB suffix mean for LMD18245T/NOPB?
NOPB stands for No Lead (Pb-Free). The LMD18245T/NOPB variant is RoHS-compliant and uses a lead-free solder finish, meeting EU Directive 2011/65/EU (RoHS 2) requirements. This is the recommended ordering option for new designs and all RoHS-restricted end markets.
What are common alternatives to the LMD18245T/NOPB?
Functionally similar alternatives include the L298N (STMicroelectronics, dual full-bridge, 46V/2A per channel), DRV8874 (Texas Instruments, 40V/4A, integrated current sense, smaller QFN package), and VNH5019A-E (STMicroelectronics, 41V/30A, automotive-grade). The DRV8874 is the modern TI replacement recommended for new designs requiring smaller footprint.
What package and pin count does the LMD18245T/NOPB use?
The LMD18245T/NOPB comes in a TO-220 11-pin through-hole package. The exposed metal tab provides a large thermal pad for heat sinking, supporting the 3A continuous rating without external heatsinks at moderate ambient temperatures. Pitch is 2.54mm (100 mil) standard.
