Power management integrated circuit (PMIC) is an integrated circuit integrated with multiple functions of power management. Power management of a given system can be divided into AC power management and DC power management. Power management includes a variety of functions such as power supply regulation, power conversion, voltage conversion, voltage regulation, power control and so on. PMIC can be classified into DC-DC converter, battery charger, AC-DC converter, gate driver, and so on. The MIC4451BN gate driver is one of the PMIC gate drivers, and it is designed to drive and protect a variety of digital circuits. It contains an adjustable BiCMOS gate driver, a junction N-MOSFET, and a Charge-pump circuit.
