This Product Selection Guide contains information to help select products in the Supervisors category on DigiKey.com
A PMIC Supervisor is designed to monitor and/or control voltage rails within a circuit with the ability to interface with a microcontroller to maintain certain power limits. The types of Supervisors are Battery backup circuit, Monitor, Multi-Voltage Supervisor, Power Supply Monitor, Regulator/Supervisor, Reset Timer, Sequencer, Simple Reset/Power-On Reset, Smart On/Off Controller, System Manager, Voltage Detector, and Watchdog Circuit.
SelectionCharacteristics
DigiKey Programmable: For verified products, DigiKey can program/flash your compiled code or configuration variables prior to shipping. For unverified products, please inquire with ProgCent.Techs@digikey.com
Type: Denotes fundamental circuit type or style, indicating the device’s core behavior and characteristics.
Number of Voltages Monitored: The number of inputs that may be simultaneously supervised by the device.
Voltage - Threshold: The typical value of a supervised supply voltage at which a device asserts or de-asserts its output.
Output: Indicates the output configuration of the device, and which type of signal it uses to communicate with the host system.
Reset: Indicates the logic sense of a device output that is used to signal other circuit elements when an invalid supply voltage condition has occurred.
Reset Timeout: The period of time that a device maintains its output in an asserted state after normal operating conditions have been established.
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.
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 to go by this terminology when designing your circuit.
