Gate Drivers ICs

LMD18400N/NOPB Description

The LMD18400N/NOPB from Texas Instruments is a high-performance, 4-channel independent high-side gate driver IC designed for demanding power electronics applications. Housed in a 20-pin DIP (Through Hole) package, this device operates over a wide supply voltage range of 7V to 28V, making it suitable for diverse industrial and automotive systems. With peak output current capability of 3A (source/sink), it ensures robust driving of MOSFETs and IGBTs. Although marked as Obsolete, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH unaffected status. The logic input thresholds (0.8V VIL, 2V VIH) ensure compatibility with TTL and CMOS logic levels.

LMD18400N/NOPB Features

• High-Side Drive: Independent 4-channel configuration for flexible system design.
• High Current Output: 3A peak source/sink current enables fast switching of power devices.
• Wide Voltage Range: 7V–28V supply range accommodates various power rails.
• Robust Construction: Through-hole mounting (20DIP) ensures mechanical durability.
• Logic Compatibility: TTL/CMOS-compatible inputs (0.8V/2V thresholds) simplify interfacing.
• Reliability: MSL 1 (Unlimited) moisture sensitivity and industrial-grade ECCN (EAR99) certification.

LMD18400N/NOPB Applications

• Motor Control: Ideal for driving high-side switches in H-bridge motor drivers for industrial automation.
• Power Supplies: Used in switching regulators and DC-DC converters requiring high-side drive.
• Automotive Systems: Suitable for electronic load switches and actuator drivers in 12V/24V automotive networks.
• Industrial Loads: Drives solenoids, relays, and inductive loads with high efficiency.

Conclusion of LMD18400N/NOPB

The LMD18400N/NOPB excels in high-current, high-side switching applications, offering a blend of performance, durability, and logic compatibility. While obsolete, its 3A drive strength, wide voltage range, and independent channels make it a pragmatic choice for legacy or cost-sensitive designs in motor control, power conversion, and automotive systems. Engineers valuing reliability and simplicity will find it a compelling solution despite newer alternatives.
