Microchip Technology TC4428EPA Overview

The TC4428EPA is a robust, high-speed, dual-channel power MOSFET driver manufactured by Microchip Technology, designed to convert TTL or CMOS input logic levels to a higher voltage and current output with minimal propagation delay. This device is specifically engineered to drive highly capacitive or low-impedance loads, making it an ideal choice for a wide range of applications, including motor control, switching power supplies, and high-speed line drivers.

Each driver channel of the TC4428EPA is capable of sourcing and sinking up to 1.5A of peak current while operating from a supply voltage range of 4.5V to 18V. The input logic level is compatible with standard CMOS or LSTTL outputs, down to 3.3V logic. The device offers enhanced latch-up protection and is designed with an inherently matched rise and fall times to provide a balanced output.

The TC4428EPA features a non-inverting and inverting driver, which can be used in tandem for push-pull applications or individually for driving two separate loads. The device's high current-driving capability and wide operating voltage range make it a versatile solution for driving power MOSFETs and IGBTs in high-side and low-side configurations.

Packaged in an 8-pin PDIP (Plastic Dual In-line Package), the TC4428EPA is characterized for operation from -40°C to +85°C, ensuring reliable performance in a broad range of industrial and consumer environments. Its robust design includes built-in protection features such as over-temperature and over-current protection, safeguarding the device and the downstream components from potential damage.

The integration of the TC4428EPA into your design will enhance system reliability and efficiency while reducing the component count and simplifying the power management design. Microchip Technology's commitment to quality and long-term availability makes the TC4428EPA a trustworthy and durable solution for your high-power driving needs.
