Microchip Technology TC4469EPD Quad CMOS Power MOSFET Driver

The TC4469EPD is a powerful quad CMOS power MOSFET driver from Microchip Technology, designed to simplify the task of controlling high-power MOSFETs in a wide range of applications. This driver is capable of converting TTL or CMOS input logic levels to high-current outputs at voltages up to 18V. Its robust design makes it an ideal choice for driving capacitive, inductive, and resistive loads, including motors, solenoids, high-power LEDs, and more.

Each driver within the TC4469EPD is capable of providing a 1.5A peak current output, which is suitable for driving large MOSFETs with high gate capacitances. The matched rise and fall times reduce the risk of cross-conduction and power loss, enhancing the efficiency of the overall system. This driver operates within a supply voltage range of 4.5V to 18V, making it versatile for various power systems.

One of the standout features of the TC4469EPD is its latch-up protection, which ensures device safety under extreme conditions. This is complemented by its high noise immunity, characterized by a 25nA typical latch-up current at 125°C, which is crucial for applications operating in electrically noisy environments.

The TC4469EPD comes in a 14-pin PDIP (Plastic Dual In-line Package), which is widely used and easy to handle in both prototyping and production environments. Its input compatibility with TTL and CMOS logic makes it a convenient choice for a range of microcontroller-based systems or any application where logic-level signal interfacing is required.

Whether you are designing an automated system, a power management module, or a high-frequency power converter, the TC4469EPD from Microchip Technology offers a reliable and efficient solution for driving your power MOSFETs. Its combination of high current capability, noise immunity, and latch-up protection ensures that your designs will perform reliably, even in the toughest conditions.
