Field Effect Transistors (FETs) are the key components to translating electrical signals into control. Though originally developed as amplifiers, they are now integral in so many modern electronic devices. In particular, they are used as gates that control indication applications like switching relays, motors and solenoids. FETs require a constant drive source in order to keep channels of operation open and closed as needed, and that is where PMIC - Gate drivers come in. FAN3225TMX-F085, a highly reliable PMIC driver for FETs, is specifically designed for automotive, industrial, and consumer applications.

FAN3225TMX-F085 is suitable for a variety of automotive and consumer applications, such as Power Door Lock, Power Seat Height Adjust, Cruise Control, and HVAC systems. It is also suitable for industrial applications such as motor drives, robotic systems and other industrial control systems. Its flexibility and low cost make it an ideal choice for replacing legacy 8- and 16-bit devices.

Features of FAN3225TMX-F085

FAN3225TMX-F085 features a wide operating voltage range of 8 ~ 28V and programmable output current range of 0.1 ~ 6A. Its low input voltage of 0.9V and wide output control of 0.25 ~ Vdd (8 ~ 28V) provide optimum performance with low power dissipation. FAN3225TMX-F085 also offers protection features against over temperature and over current, making it robust and reliable. Other features include an integrated LDO, error amplifier, power-On-Reset circuitry, and integrated protection circuit.

Working Principle of FAN3225TMX-F085

FAN3225TMX-F085 is a voltage regulator and gate driver IC. It receives a signal from the micro-processor in order to perform an operation. The signal is converted into a control voltage and this voltage is sent to the gate of the FET, turning it ON or OFF based on the signal received. The output current range is set by an external current sense resistor and is adjustable using an external clock signal.

When the signal sent from the micro-processor is a logic high, the output voltage increases, causing the FET to turn ON. On the other hand, when the signal is a logic low, the FET turns OFF, providing a ground reference on the output. FAN3225TMX-F085 also features a power-On-Reset circuit to ensure any unintentional logic levels from the micro-processor are not misinterpreted. This is important for the reliable operation of the system.
