The MC33395DWBR2 is a PMIC - Gate Driver, which offers a highly efficient, low-side switch. It is designed for use in automotive and industrial applications and is particularly suited for power switch and lighting circuit applications. The MC33395DWBR2 consists of two fully isolated, low-side, N-channel MOSFETs and a current-sense resistor. It features a wide operating voltage range from 4.5 to 18V and fast switching speeds (less than 10µs), which enable the driver to handle high currents and frequencies up to700kHz. The device also includes over-temperature protection, under-voltage lockout, and active current limitation.

The MC33395DWBR2 is used in automotive and industrial applications where an efficient, low-side switch is essential. For automotive audio and lighting circuits, the added features of the MC33395DWBR2 make it ideal for use in these applications. For example, the wide operating voltage range and fast switching speeds ensure the best performance is obtained. In industrial applications, the device can be used to control motors, pumps, and fans, as well as other equipment that requires a reliable low-side switch.

The MC33395DWBR2 consists of two fully isolated, low-side, N-channel MOSFETs, which are connected together in a series configuration, and a current-sense resistor. This allows the driver to detect the current through the lower MOSFET and control its switching action more accurately. When the switching signal is applied to the gate of the upper MOSFET, the current immediately begins flowing through both the upper and lower MOSFETs. The current-sense resistor then detects the current through the lower FET and adjusts the switching signal accordingly to turn off the lower MOSFET at the correct time. This prevents excessive power dissipation and ensures a constant and reliable output.

The MC33395DWBR2 has a number of additional features that make it ideal for use in automotive and industrial applications. It includes an active current limit function that allows the driver to detect the current in the load and automatically adjust the output power to ensure the load remains within safe limits. It also features an over-temperature protection circuit to protect the device from damage due to thermal overload. Additionally, the device includes under-voltage lockout, which prevents the device from turning on when the input voltage dips below the minimum operating voltage range.

The MC33395DWBR2 is a high-performance, low-side switch, which offers an efficient and reliable solution for automotive and industrial applications. Its wide operating voltage range, fast switching speeds, and additional features make it ideal for use in these applications. Additionally, the device’s current-sense resistor ensures that the device is accurately controlled to deliver the best possible performance.
