MAX4820EUP+T

The MAX4820EUP+T is a power management integrated circuit (PMIC) that forms part of a power distribution or load-driving system. It combines digitally programmable current-limiting and current-sensing circuits with a high-performance power MOSFET output switch. It is designed to manage power distribution and control in low-voltage, high-current applications.

It is optimized to switch up to 12V and includes a gate driver, current-sensing amplifier, current-limiting circuits, over-temperature sensing, and over-current protection. The gate driver has an input voltage range of 3.0 to 24V and it can source and sink up to 350mA. The current-sensing amplifier has a gain of 1,000V/V, allowing it to measure currents up to 20A with a sense resistor.

The MAX4820EUP+T includes both over-temperature and over-current protection features. The over-temperature protection feature has a preset threshold of +120°C and an adjustable trip point. The over-current protection feature has an adjustable trip point, allowing it to limit outputs in the event of an excessive load current.

The MAX4820EUP+T is widely used in a variety of applications, from consumer electronics and industrial automation to medical devices and automotive systems. It is well suited for applications where small size, low loss, and low standby current are important factors. The chip is housed in a small, 4mm x 4mm surface-mount package, making it easy to integrate into existing designs.

The MAX4820EUP+T provides clean switching of up to 12V and can be used in a wide range of applications, from consumer electronics and industrial automation to medical devices and automotive systems. With its combination of features, such as its gate driver, current-sensing amplifier, current-limiting circuits, over-temperature sensing, and over-current protection, the MAX4820EUP+T provides power management and control capabilities to keep the system running smoothly.
