  PMIC - Gate Drivers are semiconductor devices whose function is to act as an interface between two circuits. This type of devices is used in applications such as motor control, voltage regulation, as a motor driver for high-power switching, or as a level translator. The MIC4469ZN is a high-performance gate driver for N-channel MOSFETs and IGBTs, which provide fast switching and require high drive current..

  The MIC4469ZN is suitable for a wide range of applications, including automotive and industrial motor control, DC-DC converters, Class D audio amplifiers, and switching power supplies. It operates over a wide input supply range from 6V to 40V with low quiescent current. In addition, the device features integrated thermal protection and slew-rate control, ensuring reliable protection and performance even in extreme operating conditions.

  The MIC4469ZN offers a high-current, low-side MOSFET driver and a low-current, high-side MOSFET driver. The low-side MOSFET driver offers a 500mA peak output current, making it suitable for high-current applications, while the high-side MOSFET driver offers a 100mA peak output current for low-current applications. These drivers also feature adjustable slew-rate control, allowing the user to customize the turn-on/turn-off times for the controlled devices, reducing switching losses and EMI. The device also features a built-in thermal shutdown protection circuit, which shuts down the driver in case of overload or overheating.

  The MIC4469ZN features an adjustable frequency control, which allows the user to adjust the switching frequency in order to avoid unwanted inductive harmonics or EMI noise. The device also features an adjustable dead-time control, which allows the user to adjust the dead-time between the high-side and low-side MOSFET drivers, preventing both short circuits and shoot-through. In addition, the device can be configured to drive both MOSFETs or an IGBT.

  The MIC4469ZN is a high-performance gate driver designed to provide fast switching, high drive current, and reliable protection for motor control, power switchings, DC-DC converters and Class D audio amplifiers. The device features a wide input supply range, integrated thermal protection, adjustable slew-rate control, adjustable frequency control, adjustable dead-time control, and the ability to drive both MOSFETs and IGBTs. The device is ideal for high-power switching, voltage regulation, and motor driver applications.
