PMIC (Power Management ICs) are used to control and manage the current, power and energy signals in electrical systems. Gate Drivers are used to control the turn on and turn off of the (MOSFET) transistors used in power supplies and other power related applications. NCP5183DR2G is a Gate Driver developed by ON Semiconductor which can be used in different electronic systems requiring power management ICs (PMICs).

NCP5183DR2G is a two channel high-side gate driver, suitable for dealing with the voltages up to the 20V range. It is a stable and reliable Gate Driver and provides low jitter, low harmonic distortion and fast switching capabilities without compromising the safety of operations. It is available in a 8-lead SOIC package and has been designed for use in automotive and industrial applications. The NCP5183DR2G features two half-bridges of gate drivers with an integrated charge pump, as well as a low side driver that is adjustable and controllable. It also integrates thermal protection, motor feedback inputs and open-drain output to reduce the system’s external components.

NCP5183DR2G’s main application fields can be listed as automotive applications, measurement purposes, motor control applications, and power supply applications. Automotive applications could be like electric automobile motors and onboard charging solutions.
