ADM1272-1ACPZ-RL is a hot swap controller from Analog Devices, Inc. It is commonly used in applications such as high-power attachment and distribution of up to >45A. The chip is specified to operate with a supply voltage of 4V to 28V, a junction temperature range of -40°C to +150°C, and high-frequency ripple filter capacitor.

The ADM1272-1ACPZ-RL provides an accurate current limit, maximum current limit, over temperature protection and fault management with independent voltage control and high current operation up to >45 A. It is also designed to allow simultaneous use of multiple output voltages off the same hot-swap controller.

The device is enabled when an enable signal is asserted low. This allows the supply voltage to rise, while the enable signal is held low. When the enable pin is released, the voltage of the corresponding output will remain stable.

At the center of the ADM1272-1ACPZ-RL\'s circuitry is a current-limiting circuit, which will automatically limit current through the device when the load currents exceed the setting of the maximum current limit, reporting the fault and turning off the device. The current-limiting circuit is designed to shape the current waveform to maintain a constant current flow in both normal ( unregulated ) and overload ( current-limited ) conditions.

The over temperature protection feature of the ADM1272-1ACPZ-RL monitors the internal temperature of the device and shuts down both the voltage regulator and the current-limiting circuit when the maximum junction temperature is exceeded. This protects the device, its surrounding components, and prevents damage due to excessive heat.

Finally, the ADM1272-1ACPZ-RL features an adjustable ripple filter capacitor. This capacitor is connected between the input and output of the controller and is used to reduce the ripple voltage seen by the load. This provides better control of output voltage ripple, which improves system reliability and power integrity.

In summary, the ADM1272-1ACPZ-RL is a versatile hot swap controller ideal for high-power applications where accurate current limiting and over-temperature protection is required. Its current-limiting circuitry, adjustable ripple filter capacitor, and wide input voltage range make it an excellent choice for applications requiring high current operation and robust protection.
