The IXDI409PI is a development of PMIC - Gate Drivers. It is a monolithic, dual channel high side, low side and power MOSFET driver. The IXDI409PI is suitable for use in a variety of motor control and power supply applications. The application of this device is ideal for a wide range of industries from automotive and consumer to industrial and medical.

The IXDI409PI provides high-side and low-side protection for the control circuitry and power MOSFETs, as well as complete galvanic isolation for the controller and power MOSFETs. The IXDI409PI is suitable for applications operating from DC voltages between 6 and 42 V and able to drive loads up to 2.5A at voltages up to 24V. It is designed to provide improved RF and EMI performance regardless of market applications.

The IXDI409PI offers both flexible standby mode control and soft start operation. This allows it to be used in car battery control scenarios, where fast switching of the power supply is needed and where the current drawn is minimal. It also allows operation in a manner that minimizes current draw while still providing the necessary load switching power. With a low standalone quiescent current of 1.5 mA it is suitable for use with most automotive diagnostic tools.

The IXDI409PI is based upon a charge share managing technique known as Active Kelvin Boost. This works by ramping up the signal gradually for the high-side MOSFET during the turn-on process. This process reduces the voltage transient, thus providing a faster and smoother turn-on. This technique helps to reduce or eliminate any unwanted spluttering from the motor.

The IXDI409PI device also provides current sense functions that are used to monitor the current drawn by the driven device. This is particular useful when switching is done in multiple directions and the current must be managed for each direction. This feature helps to ensure the safe operation of the device and can be used to improve accuracy in monitoring current.

The IXDI409PI also includes integrated fault protection features that help to protect the device from over-voltage, under-voltage, and over-temperature conditions. These features help to ensure the safe and reliable operation of the IXDI409PI. The device is also pin-compatible with existing IXDI409PI devices, making it simpler and easier to upgrade existing applications.

In summary, the IXDI409PI is a high-performance, high-side and low-side MOSFET driver. It offers excellent flexibility, high-side and low-side protection, and complete galvanic isolation for the controller and power MOSFETs. It is ideal for a wide range of applications and suitable for automotive, consumer, industrial, and medical applications. The integrated fault protection features help ensure the safe operation of the device, and the low quiescent current of 1.5 mA allows for easy operation with automotive diagnostic tools.
