Power management integrated circuits (PMICs) are integral components of most modern circuit designs. They help control and monitor the power supply of the circuit, as well as regulating the current and voltage output. Gate drivers are a type of PMIC that are used to drive MOSFETs and insulated-gate bipolar transistors (IGBTs) in electronic applications. They are commonly used in switching applications that require a high current or voltage. The MAX8791GTA+T is a high-performance gate driver ideal for power applications that are both heavy-duty and noise-sensitive. By understanding the advantages and applications of the MAX8791GTA+T as well as its working principle, designers can better utilize the product to their applications’ advantage.
