MIC4468CN

The MIC4468CN is an integrated chip that belongs to the family of PMIC – Gate Drivers. It is capable of providing an output current of up to 8 A and is specifically designed to be used with low voltage, low power logic circuits and motor control applications. It is built on a monolithic CMOS technology that combines both high-side and low-side power transistors, so it provides galvanic isolation between the power supply and the load, as well as reducing the power losses associated with traditional gate drivers. The MIC4468CN also has an integrated internal shuttle diode and a current limitation for enhanced protection features.

The main application fields for the MIC4468CN are motor control, power stages, and logic level gate switches. The MIC4468CN can be used to drive a number of loads, including relays, actuators and high-side switches. It offers a low-current gate and high-current outputs, allowing it to control a wide variety of loads. Additionally, it can be used to drive a bipolar stepper motor, solenoid, and a Brushless DC (BLDC) motor.

The MIC4468CN has a main driver channel, which is capable of providing up to 8 A of output current with a minimum of 1.5 A of current limiting. This is controlled by a logic-level input, which is compatible with 3.3 to 5 V logic gates. In addition, it has an integrated over-current protection circuit and a current sense element for monitoring Channel A output current.

In terms of its working principle, the MIC4468CN is designed to switch two power transistors on and off in order to drive the load. When the logic input from the controller is low, the MOSFETs are off and the output is in its idle state. When the logic input is high, the MOSFETs are driven on and the output is enabled. The MIC4468CN also uses an internal sensing element to detect over-current situations when the load is driving an excessive current, and then the main driver channel is disabled. The MIC4468CN can be used in any application where isolated power is needed and low current gate sources are available.

In conclusion, the MIC4468CN integrated chip is a part of the family of PMIC – Gate Drivers, which provides an efficient solution for driving a variety of loads, with enhanced protection features and low losses. It can be used in a wide range of applications, ranging from motor control to power stages, and offers an integrated current sense element for monitoring Channel A output current. It can be used in any application where isolated power is needed and low current gate sources are available.
