Hetek HKTD80N03 redefines the power boundary of 18V power tools with its unconventional 80A high-current design. As a national-level high-tech enterprise, we have achieved the perfect integration of an ultra-low on-resistance of 4.8mΩ and TO-252 packaging through the ASM fully automated production line at our manufacturing base in South China. Compared with traditional solutions, it reduces power consumption by 15%, completely solves the overheating problem of impact drills and angle grinders during continuous high-load operation, and extends battery life by up to 20%.

Core Challenges in Motor Drive for Power Tools

Motor drive systems in power tools face three major technical bottlenecks:

1. Peak current impact: 3-5 times peak current surge during startup (up to 60A in conventional 18V lithium battery systems), which easily causes failure of switching devices.
2. Heat dissipation constraints: Limited heat dissipation space in metal-enclosed equipment leads to junction temperatures exceeding 150°C during continuous high-current operation.
3. Wide battery voltage fluctuation: The battery voltage ranges from 14V to 24V, requiring devices to have sufficient voltage tolerance margin. Traditional MOSFETs suffer from conduction losses exceeding 2W under 80A operating conditions, significantly reducing tool runtime.

Precise Matching of Key Features to Application Scenarios

HKTD80N03 perfectly adapts to power tool requirements through three core features:

• 80A continuous drain current provides 1.3 times peak current redundancy, easily handling motor startup surges.
• Ultra-low 4.8mΩ on-resistance results in approximately 3W power consumption at full load, a 40% reduction compared to similar products.
• TO-252 package with low thermal resistance, combined with PCB copper layout, controls junction temperature below 120°C.
• 30V voltage rating is specifically designed for 18V lithium battery systems, with a 33% voltage margin reserved to effectively withstand voltage spikes from switching inductive loads.

Application Design Recommendations

In drive circuit design:

• Gate drive voltage should be controlled within 10V±1V to ensure optimal on-resistance performance.
• A source series resistor is recommended for overcurrent protection.
• A pull-down resistor should be paralleled in the gate circuit to prevent false turn-on during power-up.
• PCB layout should minimize power loop paths, with top-layer copper area of over 20 mm³ reserved as a heat dissipation zone.
• It is advised to use parallel fast recovery diodes rated at 30V/100A or higher to absorb inductive spikes.

Summary

With its three major advantages—high current capacity, low loss, and strong heat dissipation—the HKTD80N03 stands as the ideal choice for motor drive in 18V-class power tools. Leveraging Hetek’s large-scale manufacturing base with guaranteed 产能 and advanced production processes, its perfect integration of 80A current handling capability and 4.8mΩ on-resistance not only meets the power demands of high-performance tools but also significantly extends battery life through improved energy efficiency, enabling the creation of next-generation "powerful and long-lasting" power tools.
