Power management involves receiving and modifying power from a device or other source. Power management integrated circuits (PMICs) are specialized electronic ICs used to regulate the flow of power and provide power management functionality. One such PMIC is the MAX8520ETP+: a PMIC with integrated Hi-Side MOSFET and a bootstrap diode. This IC is designed to provide quick gate switching times, a high slew rate, a low power supply current and robust protection features.

The MAX8520ETP+ is designed for DC/DC buck, step-down and step-up applications offering an expression of up to 80V – the highest voltage rating available in the MAX8520 series. The device integrates two high-side power MOSFETs and a single low-side MOSFET with a dedicated bootstrap diode. It also features integrated tiny digital and analog monitoring controllers, which detect input voltage, output current and temperature. Together, these features deliver consistently reliable performance.

The MAX8520ETP+ has 4 dedicated PWM mode outputs, making it compatible with all types of external DC/DC converters. The device also includes a rail-to-rail output voltage range, which allows it to handle small-signal requirements even in challenging environments. Additionally, the integrated load-dump diode protects against voltage transients created by load-dump effects.

The MAX8520ETP+ features a wide operating temperature range of -40 to +125°C, enabling it to be used in harsh environments. The device also offers low-noise operation, higher power efficiency and excellent thermal insulation. This ensures that anypower loss due to heat dissipation is minimal.

To help ensure low power consumption and minimize device size, the MAX8520ETP+ integrates fast rise/fall times, a high slew rate and a low on-resistance MOSFET. This allows the device to provide reliable performance and consistent power delivery without the need for external components.

Using the MAX8520ETP+ in a buck converter configuration allows the device to control the output voltage using feedback control, while preventing load drops. The device also provides speed control, allowing the output voltage to be adjusted as necessary. This makes the MAX8520ETP+ a versatile solution for a wide range of applications.

The MAX8520ETP+ contributes to improved machine-to-machine communication, which is essential for reliable power distribution and intelligent management. It has a wide input voltage range of 4.75 to 80V, and a top-range current-controlled output voltage of 2.1 to 80V. The device also supports the I2C communication protocol, allowing it to be connected to both type-c and ethernet applications.

The MAX8520ETP+ is a low-cost and efficient power management solution for applications including buck converters, point-of-load (POL) regulators, buck converters, and switching regulators. Its wide range of features and benefits make it an ideal solution for any power management need. The device is especially suited for applications where high precision, low noise and high efficiency are important, such as industrial automation and medical equipment.
