Working Principle

The JTM037PR2DCC16Q driver works based on an optical isolation technique. It consists of an input stage and an output stage, which are optically coupled using an IRED/photo-diode. The input stage is an IC containing logic input pins, current and voltage monitoring, and active elements like amplifiers and drivers. The output stage consists of power MOSFETs with drive circuitry, current and voltage monitoring circuits and external components like voltage and current sensing resistors.

The input stage monitors the input signal voltage and compares it to a reference voltage, adjusting the output signal accordingly. The output stage consists of several complex functions, depending on the requirements of the application. The drive circuitry gives the MOSFETs appropriate gate drive, and the current and voltage monitoring circuits provide overcurrent and overtemperature protection.

The optically isolated JTM037PR2DCC16Q driver provides high-side and low-side control of power MOSFETs. It offers current limit and sensing diode protection, making it suitable for many applications. The driver’s wide range of threshold supply voltage compatibility, from 7V to 20V, makes it a versatile choice for driving high-current switching applications.
