Microchip MD1810K6-G: High-Voltage, High-Speed Power MOSFET Driver

In the realm of power electronics, the efficiency and performance of switching systems are paramount. The Microchip MD1810K6-G stands out as a critical component engineered to meet these demanding requirements. This high-voltage, high-speed power MOSFET driver is designed to deliver robust performance in applications where precise control and rapid switching of power MOSFETs are essential.

The MD1810K6-G is capable of operating with supply voltages up to 18V, making it suitable for a wide range of high-power scenarios. Its ability to drive both high-side and low-side N-channel MOSFETs in half-bridge configurations provides designers with exceptional flexibility. The device incorporates advanced level-shift circuitry, ensuring reliable operation in high-voltage environments while maintaining signal integrity.

One of the key features of this driver is its high-speed switching capability, with propagation delays typically under 25 ns. This minimizes switching losses and enhances overall system efficiency, which is crucial for applications like switch-mode power supplies (SMPS), motor control, and Class D audio amplifiers. Additionally, the driver offers robust protection features, including under-voltage lockout (UVLO) for both the high-side and low-side sections, which safeguards the system from operating under insufficient voltage conditions.

The integration of shoot-through protection further prevents simultaneous conduction of the high-side and low-side MOSFETs, a common cause of failure in bridge circuits. With a peak output current of 2.5A, the MD1810K6-G can quickly charge and discharge large MOSFET gate capacitances, ensuring sharp switching transitions and reducing electromagnetic interference (EMI).

Housed in a compact 6-pin SOT-23 package, this driver combines high performance with a small footprint, making it ideal for space-constrained applications. Its wide operating temperature range from -40°C to 125°C ensures reliability in harsh environments.
