### Overview of TC4426EOA713 The **TC4426EOA713** is a high-speed, dual-channel, inverting MOSFET driver manufactured by Microchip Technology. It is designed to bridge the gap between low-power control signals (from microcontrollers or PWM ICs) and high-power MOSFETs or IGBTs. --- ### Key Technical Specifications | Parameter | Value / Range | | :--- | :--- | | **Logic Type** | Inverting (Input High = Output Low) | | **Number of Channels** | 2 | | **Peak Output Current** | 1.5A | | **Supply Voltage (Vdd)** | 4.5V to 18V | | **Input Logic Low** | 0.8V (max) | | **Input Logic High** | 2.4V (min) | | **Rise / Fall Time** | 25ns / 25ns (into 1000pF load) | | **Package Type** | SOIC-8 (Surface Mount) | | **Operating Temp** | -40°C to +85°C | --- ### Internal Functional Components 1. **Input Buffer:** Features CMOS/TTL compatible inputs with hysteresis to prevent false triggering from noisy signals. 2. **Level Shifter:** Translates low-voltage logic signals up to the Vdd supply rail. 3. **Power Output Stage:** A specialized totem-pole stage capable of sourcing and sinking 1.5A peak current to quickly charge/discharge the gate capacitance of a MOSFET. 4. **Protection Circuitry:** Built-in latch-up protection (up to 0.5A reverse current) and ESD protection. --- ### Pin Configuration (SOIC-8) | Pin # | Name | Function | | :--- | :--- | :--- | | 1 | NC | No Internal Connection | | 2 | IN A | Control Input for Channel A | | 3 | GND | Ground | | 4 | IN B | Control Input for Channel B | | 5 | OUT B | Inverted Output B | | 6 | VDD | Power Supply (4.5V - 18V) | | 7 | OUT A | Inverted Output A | | 8 | NC | No Internal Connection | --- ### Typical Applications * **Switching Power Supplies (SMPS):** Driving the gates of power MOSFETs at high frequencies. * **DC-to-DC Converters:** Managing power flow efficiently by reducing switching losses. * **Motor Controllers:** Driving H-bridge circuits for small to medium DC motors. * **Pulse Transformer Drivers:** Providing the necessary current to drive inductive loads. --- ### Why use the "713" Suffix? The **713** suffix in the part number specifically indicates that the component is supplied in **Tape and Reel** packaging, which is intended for automated high-volume PCB assembly (Pick-and-Place machines).
