Power Management Integrated Circuits (PMICs) are essential in enabling the latest advancements in electronics and computing power. PMICs help manage energy consumption, enable efficient power conversion, and enable safe and reliable operations. Supervisors are a key PMIC sub-category designed to protect the circuitry and components of the system from damage due to overcurrent, under-voltage and other similar conditions. The LM809M3-4.00/NOPB parts are advanced integrated supervisors specifically designed for voltage/current monitoring applications and represent the latest innovations in integrated power management.

The LM809M3-4.00/NOPB are single-chip microprocessor supervisor integrated circuits that offer enhanced pro power protection through:

• Current monitoring
• Voltage monitoring
• Temperature monitoring
• Adjustable thresholds for accuracy
• Automatic reset timeout

The LM809M3-4.00/NOPB parts are designed to be used in industrial, automotive and consumer electronics applications where sophisticated power supply protection is required. The low-power circuit design requires just 4uA of current while operating in power-on reset (POR) mode, making it ideal for portable or battery-powered applications. The fault inputs are programmable over a wide operating range and can be configured to detect both over-voltage and under-voltage conditions. The reset timeout can also be set for a variety of applications, from microseconds to minutes. In addition, the parts are capable of temperature monitoring, independent of the control inputs, and the threshold level can be set using an external reference voltage.

The LM809M3-4.00/NOPB parts feature integrated voltage and current monitoring circuitry with programmable thresholds. The voltage monitoring section is designed to detect over-voltage and under-voltage conditions while the current monitoring section is designed to detect over-current conditions. In addition, the parts can be configured to generate an interrupt response when one or both conditions are detected. This feature is useful for applications that require immediate notification of fault conditions.

The LM809M3-4.00/NOPB parts also feature adjustable reset timeout. This feature allows the user to set the length of time between a fault condition occurring and a reset being generated. This feature can be used to ensure that the system is given enough time to respond to a fault condition before resetting, or to ensure that the system is allowed enough time to complete shut-down operations before resetting. The reset timeout can be set from microseconds to minutes depending on the application.

The LM809M3-4.00/NOPB parts also feature temperature monitoring, which can be enabled or disabled using an external input. The threshold for temperature monitoring can be adjusted using an external reference voltage. The temperature monitoring feature can be used in applications that require monitoring of the ambient temperature in order to ensure safe operation of the system components.

In summary, the LM809M3-4.00/NOPB parts are advanced supervisors specifically designed for voltage/current monitoring applications. The parts offer a comprehensive set of features designed to protect systems from damage due to overcurrent, under-voltage and temperature conditions. The parts feature current, voltage and temperature monitoring, adjustable thresholds and reset timeout, making them suitable for a wide range of industrial, automotive and consumer electronics applications. The low power requirements and adjustable thresholds make them particularly well-suited for battery powered, portable applications.
