MAX17603AUA+ is an integrated gate driver, which belongs to a category of PMIC – Gate Drivers. It is equipped with enhanced fault reporting, current sensing, and fast MOSFET-based outputs, making it an ideal choice for power converters with medium output current demands.

The MAX17603AUA+ is designed for low and high voltage inverter, motor drive, or motion control power systems that require precision and convenient driving of FETs. The integrated current sense amplifier and fault reporting capabilities ensure inrush current protection, fast switching performance and safety monitoring when used in high-voltage automotive, industrial, solar and other tough applications.

The MAX17603AUA+ is a three-phase gate driver that can drive both N-channel MOSFETs and IGBTs with up to 150V of total supply. The device has two dedicated driver channels each with a single-ended PWM input and TTL-compatible /ENABLE input. The PWM inputs provide 0-100% duty cycle control while the /ENABLE input allows adjustable off-time modulation of the drivers. The MAX17603AUA+ has an optimized output design where the DRV1 and DRV2 outputs are optimized for low voltage applications.

The gate driver includes a fully differential current sense amplifier (CSA) with a maximum output voltage of ±100mV. The current sensing range is programmable from 1mA to 16A peak. The CSA provides fault reporting including overcurrent, undercurrent, and overvoltage conditions. It also works with single-ended or differential Hall sensor inputs to measure the line voltage.

The MAX17603AUA+ features ESD protection with up to 15kV HBM protection for all pins. It is available in space-saving 16-Pin DOC3 DFN and SOT-23 packages. The MAX17603AUA+ is voltage-regulation independent and supports a wide input voltage range of 4.75V to 18V, ideal for most automotive and industrial applications.

In summary, the MAX17603AUA+ is a versatile gate driver for medium current FETs or IGBTs applications, providing fast switching performance and safety monitoring in challenging environment. The integrated current sense amplifier and fault reporting capabilities, along with the ESD protection make it an ideal choice for automotive, industrial applications, solar and other tough applications.
