This Product Selection Guide contains information to help select products in the Hot Swap Controllers category on DigiKey.com
PMIC - Hot Swap Controllers are semiconductors that provide the in-circuit protection and control features needed to allow other components to be inserted or removed from a circuit while there is live power. Useful in computer networking and general-purpose power systems, hot-swap controllers are mainly differentiated by features such as output current, number of controlled channels, and special features such as auto-retry, fault timeout, and protections.
SelectionCharacteristics
Type: Indicates the style and configuration of the device.
Number of Channels: The number of individual channels available within the device.
Internal Switch(s): Indicates whether or not a device integrates the power transistor(s) needed for manipulation of the power source a device is intended to control.
Applications: Application is the type of equipment or environment the device will be used in, typically they are tested and rated by a third party to ensure certain minimum standards for the application they are intended for.
Features: These are different capabilities or properties of the device such as auto retry, fault timeout, or UVLO.
Programmable Features: These are different capabilities or properties of the device whose behavior or functionality can be controlled or modified programmatically.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Current - Output (Max): The maximum amount of current that can be output by the device.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Current - Supply: This represents the maximum current to which a device will meet its given specifications. Exceeding this current may damage the device and/or other system components.
Mounting Type: Indicates how the device is attached.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Supplier Device Package: This is what the manufacturer calls the package of this device. They are manufacturer specific. It is typically best to use the actual dimensions from the datasheets rather than use this terminology when designing your circuit.
