IXDE509D1

The IXDE509D1 is a high-efficiency gate driver, designed to operate at high efficiency levels with a high level of safety. This device is classified as a PMIC – Gate Drivers. It is designed to fit the transistor family with tailored features to optimize the performance of power transistors in power switching at low supply voltages.

IXDE509D1 is designed with a low side gate driver and a high side gate driver that allows the device to control high voltage transistors. The low side gate driver can perform controlling operations with a max of 32V rating, while the high side gate driver can control transistors up to 60V. It has a 0.2A/1A source current and 0.2A/1A sink current capacity.

The IXDE509D1 has an integrated delay feature to control the rise and fall of the voltage, protecting the IC from the damaging effects of electromagnetic interference or excessive voltage caused by an EMI event. It also allows the system designers to adjust the speed of the switching process and off-time to meet the needs of various applications. This device meets guidelines of low standby power and low-noise operation.

The IXDE509D1 is also designed for applications that require burst of high current, such as power regulation, motor control, and computer peripherals. It supports current sensing, temperature sensing, and voltage sensing, optimizing the performance of power transistors in power switching applications at low supply voltages. The device supports full-on, full-off and partial-on switching, ideal for PWM applications.

The working principle of the IXDE509D1 includes a switching on or off cycle. When the switch is turned on, the low side gate driver begins its cycle by initializing an electrostatic charge to the base of the transistor, slowly ramping up the current and maintaining it until the switch reaches full "on" position, when the electromotive force,is removed and the current is shut down. Likewise, when the switch is off, the device slowly ramp downs the current and maintains it until it reaches full "off" position.

The device also features a hysteresis control circuit, which will ensure that the gate voltage always remains at the desired level. This eliminates the possibility of a false triggering of the device, thus ensuring safe and reliable operations. In addition, the IXDE509D1 supports soft start, which is a feature used to slowly increase the voltage of the transistor beginning from its initial state. This soft start feature helps reduce the inrush current when the transistor is being switched on or off and prevent any potential damage to the components of the circuit.

IXDE509D1 is a highly efficient and highly reliable gate driver PMIC, designed to simplify the design of power switching applications. It offers features such as regulated switching, hysteresis control, current sensing, and low standby power to optimize the performance of power transistors. The device also provides a high degree of safety, protecting the IC and the rest of the system from the damaging effects of excessive voltages.
