MAX15068ATP+TG2Z application field and working principle is part of the PMIC - Hot Swap Controllers category. The MAX15068ATP+TG2Z hot swap controller from Maxim Integrated  is designed for general-purpose power-system protection against hot-plugging events, utilizing two independent and configurable current-limit thresholds and an open-drain fault flag. This makes it capable of safely powering up, powering down and protecting electronic circuits during hot-plugging events. 

The MAX15068ATP+TG2Z device has a dual, 200-mA/100-mA current-limiting architecture that provides the required power-up and power-down current-limiting protection. The MAX15068ATP+TG2Z provides two sense inputs that allow the use of an external resistive voltage divider to accurately detect an overcurrent condition. The device’s open drain fault flag output is also provided to signal overtemperature, overcurrent and undervoltage conditions.

The MAX15068ATP+TG2Z device offers a wide range of features. The device allows for soft start-up by either capacitively discharging the output voltage at turn-on, or providing a single-output start-up current profile. This eliminates inrush current peaks and momentary overcurrent conditions that potentially interrupt operations or trip protected circuits. The device also features four separate turn-off levels for configurable resistance-limited overcurrent protection that can sense a separate power supply if required. This provides a buffer between different power rails, such as differential voltage rails or a 5V supply rail, to reduce hot-plug event risks while maintaining investment protection.

The MAX15068ATP+TG2Z device is programmed by either dip switches or configurable logic. This allows a wide range of current-limiting configurations that can be programmed and updated easily and quickly. Logic circuitry is also provided in the device to detect when power is lost or when input voltage is below a user-defined threshold, and to inform the external circuitry when this occurs.

The low voltage threshold detection circuit in the MAX15068ATP+TG2Z device provides an input for sensing a low voltage condition and turning off an output if necessary. When an output is disabled and terminated, the device will generate an overcurrent signal from the logic outputs to notify authorized personnel that an output has shut off. This allows for rapid response to prevent further damage to the connected circuitry.

The MAX15068ATP+TG2Z device is packaged in a small 6-pin SOT package, providing an excellent form-factor for high-density circuit boards and tight layout requirements. It also includes a wide range of safety and protection features that protect upstream and downstream electronics during hot-plug events or power-up or power-down operations.

In summary, the MAX15068ATP+TG2Z device provides a precise, flexible and high-performance hot swap controller solution for a wide range of applications. It helps eliminate the risk of overcurrent damage that can occur during hot-plugging, while also protecting against hot-plugging events, power-up and power-down operations. It can be used in a variety of applications, including industrial, automotive and computer power systems. The various features and options provided by the device enable customers to customize it to suit their specific needs.
