Working Principle of MIC33263YGK-TR

The MIC33263YGK-TR is a single phase, low-side driver with a fast response times and internal over-voltage protections. It utilizes proprietary adaptive Flyback technology for optimized switching performance. This driver is protected by reverse kV discharge and under-voltage lockout. It is protected from over current and over temperature and provides high switching frequency. It operates from an input voltage of 4V to 20V and can provide up to 40A peak output currents.

The MIC33263YGK-TR utilizes an internal comparator and drive circuitry to detect input voltage levels above or below the designed operating range. If the input voltage exceeds the maximum value, the driver provides over voltage protection by shutting down the internal driver circuit. If the voltage drops below the minimum value the driver enters into a fault state, preventing the circuit from operating. The MIC33263YGK-TR also features an adjustable switching frequency, which can be set to ensure compatibility with system-level requirements.

The driver uses an external FET to source or sink current, making it a versatile and powerful solution for a variety of applications. It utilizes a current sense amplifier to detect real-time switching current levels, allowing for fast response time and accurate current control. The MIC33263YGK-TR is also equipped with an over temperature protection circuit, which shuts down the driver circuit if the device temperature exceeds a pre-defined threshold.

Conclusion

The MIC33263YGK-TR is a single phase, low-side driver with a fast response times and internal over-voltage protections. It is designed for high power applications, such as motor control, active power factor correction (PFC), solar power maximum power point tracking (PVMPPT), and high-power lighting.
