The MAX8552EUB+T is a highly integrated, low-voltage, 1.2A, push-pull, single-output, programmable gate-drive power management IC (PMIC). This device is designed to provide an integrated solution for driving both small- and medium-power power MOSFETs (or IGBTs) from a single supply rail as low as 1.8V. The MAX8552EUB+T power management IC is optimized for high-performance switching applications such as automotive, consumer and industrial applications.

The MAX8552EUB+T integrates two 5.0A/10.0A peak gate drivers, two adjustable voltage references and a logic-controlled disable function, eliminating the design and component costs associated with discrete solutions. This feature-rich device also includes soft-start, under-voltage lockout (UVLO), polarity inversion, and a programmable dead-time generator on each channel. The device\'s adjustable voltage reference output can also be used to drive an external load.

The MAX8552EUB+T can be used in a variety of applications, such as off-line AC-DC converters, DC-DC converters, motor drives and lighting applications. This device has a typical operating supply range of 1.8V to 5.5V, making it ideal for low-voltage applications. The integrated gate drivers offer a Peak Output Current of 5.0A and 10.0A, respectively. Both channels have a Rise/Fall time of 8ns and 8.5ns, respectively.

The working principle of the MAX8552EUB+T consists of two channels (A and B) which can be independently programmed to provide a positive output voltage (Vout+), a negative output voltage (Vout-), or push-pull outputs with defined dead-time between them. The MAX8552EUB+T includes two 5.0A/10.0A peak gate drivers with Rise/Fall times of 8.0ns/8.5ns and two adjustable voltage references (Vref±). The voltage references can be programmed with a simple external resistor divider to set the maximum output voltage. The device also offers a programmable dead-time generator which can be used to prevent output shoot-through. The device also includes a logic-controlled disable function and an under-voltage lockout (UVLO) circuits to prevent device damage during power up and power down.

In summary, the MAX8552EUB+T is a highly integrated, low-voltage, 1.2A, push-pull, single-output, programmable gate-drive power management IC that is optimized for high performance switching applications. The device\'s adjustable voltage reference output can be used to drive an external load and its integrated gate drivers offer a Peak Output Current of 5.0A and 10.0A, respectively. The integrated dead-time generator and disable function provide a level of safety and protection for the device and its output signals. The MAX8552EUB+T is ideally suited to applications such as off-line AC-DC converters, DC-DC converters, motor drives and lighting applications.
