PMIC, or power management integrated circuit, is a type of integrated circuit designed to manage and control power to enable the efficient operation of devices, systems and electronics. PMIC devices address the needs of complex power systems and are responsible for managing power inside end products such as set-top boxes, tablets, smartphones and more. Many PMIC devices are digital, but some are analog and are used for a variety of applications, from battery and regulator management to digital signal processing and more. Gate drivers, a type of PMIC, are dedicated devices designed to provide proper signals and currents to turn on and off power FETs or IGBTs. IXDN609SIA is an example of a PMIC gate driver.

IXDN609SIA is a directly driven, low-side N-channel MOSFET gate driver with the appropriate switching capability to meet the rigorous requirements of modern power management architectures. It features advanced design techniques to provide surge protection, negative charge pump, and adjustable current limiting protection. It is geared to support adjustable DC/DC converter architectures, and its design takes into account the needs of both current-mode and voltage-mode control. Additionally, the IXDN609SIA is designed for improved propagation delays, shooting up to 50% faster than the presently available solutions. This ensures the driver will be able to switch faster without compromising efficiency.

The IXDN609SIA’s working principle is aimed to provide high peak output drive current (1.3A) and pre-driver assistance, resulting in a shorter rise and fall time. This gate driver is designed to drive high-side and low-side N-Channel MOSFETs in isolated power conversion topologies. It is a low-power, single-supply MOSFET with both output and control-logic levels. The driver performs switching smoothly with ouput pulse width modulation and is able to maintain control in a wide-input range with its adjustable dead time feature.

IXDN609SIA’s applications span a variety of industries, as its features make it suitable for use in battery charging systems, LED drivers, automotive, audio amplifiers, and otherlinear and switched-mode power supply topologies. It can also be used in DC/DC converters, low-dropout regulators, motor drivers, and other power distribution circuits. IXDN609SIA is available in a high-voltage (14V) and low-voltage (7V) versions, both cooling methods support together with various packages.

To summarize, IXDN609SIA is a gate driver PMIC designed specifically to drive high-side and low-side N-Channel MOSFETs in isolated power conversion topologies. Its advanced design techniques provide surge protection, negative charge pump, adjustable current limiting protection, and more. It has its applications in many industries, including automotive, battery charging systems, LED drivers, audio amplifiers, and other linear and switched-mode power supply topologies. IXDN609SIA is available in a high-voltage (14V) and low-voltage (7V) version, with various packages.
