Power Management Integrated Circuits (PMICs) are a type of integrated circuit (IC) that is used to manage a system’s electrical power. PMICs combine different functional blocks such as DC/DC converters, linear regulators, and supervisory circuits on a single chip. These ICs are designed to help reduce external component count, reduce board space, and simplify power supply design.

One type of PMIC is the Supervisor. Supervisors are typically used in place of a microcontroller (MCU) or microprocessor (MPU) reset circuit, though some can take on other functions. Supervisors prevent MCUs and MPUs from freezing or continuing to run after a power fault. Supervisors are suitable for protecting against numerous power-related problems such as brownouts and power sequencing issues.

The LM3724EM5X-3.08/NOPB is an example of a PMIC supervisor. It is a highly integrated circuit that combines a reset, a watchdog timer, and a power-fail detect circuit in a single package. The device is designed to be used with a wide range of microcontrollers, microprocessors, and digital signal processors (DSPs).

The LM3724EM5X-3.08/NOPB is designed to reset the system on power faults or fault conditions that are deemed to be unsafe. It can also be used to detect power faults and event cycles, and can be configured to provide interrupts or system reset based on external conditions.

The reset output of the device is an open collector which can be driven low manually or by an external circuit or IC. The reset is asserted when the voltage is below the threshold voltage and remains asserted until the voltage rises back above it. The reset time is adjustable from 1ms to 1s by adjusting the external capacitor.

In addition, the LM3724EM5X-3.08/NOPB features a watchdog timer, which monitors the activity of the target system and resets the system upon a timeout. The watchdog timer is programmed via an external capacitor and can be set through the use of external resistors.

The LM3724EM5X-3.08/NOPB also features a power-fail detect (FPD) circuit, which is used to detect power faults, such as brownouts or power sequencing issues. The FPD circuit output is an active-low open collector, which can be connected to an interrupt line of a microcontroller, allowing the microcontroller to react to the power fault.

The LM3724EM5X-3.08/NOPB is an example of a PMIC supervisor that can be used to protect microcontrollers, microprocessors, and digital signal processors against power-related problems. It is designed to monitor power faults and provide a reset or interrupt upon detection, making it a useful device for power management solutions.
