IXDN602SI

High performance gate drivers are key components in power management integrated circuit (PMIC). IXDN602SI is a versatile gate driver for low side N-Channel MOSFETs for high-side configurations of up to +40V. This device is widely applied in many industrial applications.

IXDN602SI Application Fields

The IXDN602SI offers numerous advantages such as its ultra-low start-up current of 40mA, adjustable switching frequency of up to 10MHz and wide operating range from -40°C to +125°C. Such characteristics make the device ideally suited for a wide range of low side MOSFET applications such as:

• High-side switching in industrial and automotive applications
• Power management and control in servers, data centers, and storage systems
• Home appliances such as ovens, microwaves, and refrigerators
• Safety and security systems such as fire alarms and security cameras
• Lighting solutions including LED drivers, high-intensity discharge (HID) drivers, and fluorescent driver solutions

IXDN602SI Working Principle

The IXDN602SI is a low-power MOSFET gate driver designed to deliver outstanding performance in harsh conditions. It features an adjustable current-limit range of 10mA to 60mA, allowing users to adjust the turn-on and turn-off speed of the low side N-Channel MOSFETs to best suit their application. The IXDN602SI also features adjustable under-voltage lockout, a 20kHz frequency limit, as well as short-circuit protection. Additionally, the device is also equipped with UVLO, LDO, thermal shutdown, and an adjustable soft-start feature for improved system performance and robustness.

At the heart of the IXDN602SI is an advanced driver architecture that consists of an input stage and a power output stage. The input stage delivers the gate voltage signal as a pulse-width modulated (PWM) signal to the power output stage. The power output stage then converts the PWM signal into a high current drive, allowing the low side N-Channel MOSFET to be driven with low start-up current levels and low power losses. The IXDN602SI also features an over-temperature protection circuit that protects the device from over-temperature conditions and ensures proper operation.
