Not all alternative chips can achieve "seamless integration," but PT5619 delivers pleasant surprises in both compatibility and performance, allowing you to replace the chip without "major overhauls."

The most troublesome "PCB modification dilemma" is directly solved by PT5619! It has fully corresponding pins with **6288, requiring no changes to the PCB design. Simply plug it in and it works, eliminating the time and cost of redrawing the board, making samples, and testing.

What's more, PT5619 is compatible with three logic levels: 3.3V, 5V, and 15V. No matter which controller you used before, it can be easily adapted, truly achieving "plug-and-play."

Replacement is not just "making do"—it's "upgrading"! Compared to **6288, PT5619 excels in core performance:

• Stronger driving capability: Sink/source current reaches 1200mA/2000mA, enabling more stable driving of high-speed power MOSFETs and IGBTs. It handles scenarios like motor startup and high-load operation with greater ease.

• More comprehensive protection mechanisms: Built-in dead-time control and cross-conduction protection for upper and lower switches fundamentally prevent damage to half-bridge circuits. Both high-side and low-side integrate undervoltage lockout (UVLO) circuits, preventing power device damage caused by low supply voltage and ensuring safer equipment operation.

• Enhanced anti-interference capability: Adopting advanced high-voltage BCD process and common-mode noise cancellation technology, it operates stably even in high dv/dt noise environments. It also withstands a wide range of negative transient voltages, performing exceptionally reliably in complex environments such as power tools and outdoor power supplies.

Wide temperature adaptability: Operating temperature range covers -40℃ to 125℃, ensuring stable performance whether in cold outdoor environments in northern regions or inside high-temperature industrial equipment.

Many devices using **6288 are battery-powered, such as power tools and portable small appliances.

PT5619 is specifically designed with a standby mode, controlled via the ENB pin. Once in standby, its quiescent current drops to as low as 46μA (typical value), which can significantly extend battery life and enhance product competitiveness.

Not only can PT5619 replace **6288, but it also has a wide range of applications. It is competent for all scenarios requiring three-phase motor drive or three-phase inverter:

• Power tools: Electric drills, electric saws, angle grinders, etc. Its strong driving capability and high reliability meet the needs of frequent start-stop and high-load operation.

• Home appliance field: Three-phase motor drive for air conditioners and washing machines. Its strong anti-interference capability ensures the stable operation of home appliances.

• New energy products: Balance bikes, electric scooters, small energy storage inverters. Its low-power consumption feature is suitable for battery-powered scenarios, and its wide-temperature design can cope with outdoor environments.

• Industrial control: Three-phase servo motor drive and industrial inverters. It can work stably in complex industrial environments and reduce equipment failures.

What’s most reassuring right now is that PT5619 has ample stock. There’s no need to wait for months for delivery—whether it’s small-batch sampling or large-volume procurement, all needs can be met. Orders can even be shipped as quickly as the same day, helping you restart production lines rapidly and sparing you from worries about losing customers.

What’s more, as a professional chip manufacturer, Pucheng Technology ensures reliable quality. Every single chip undergoes rigorous testing, so you can feel confident even in bulk applications.
