PMIC (Power Management IC) refers to integrated circuits that control the power supply and other power management functions. Specifically, it refers to the parts used to monitor the technical requirements of a system, such as the voltage, current and other characteristics, that can be maintained by the application of power techniques. As a supervisor, the SM72240E/NOPB is a programmable input support device that monitors the processor supply current and protects against over-voltage, under-voltage and over-temperature conditions.
The SM72240E/NOPB is designed to protect various single and multiple processor systems from voltage faults through its protection circuit and reset signal generation. This device is mainly composed of an internal voltage comparator, a watchdog and a reset signal output circuit. The SM72240E/NOPB is an adjustable supervisor with an under-voltage (UV) cutoff threshold of 2.6V-5.5V. It uses a 6-pin SOT-23 package to reduce space requirements.
The SM72240E/NOPB has several applications, such as in Personal Computers, Mobile Phone Platforms and applications with LDO linear regulators, PMICs and DC-DC converters. The SM72240E/NOPB can be used as a reset and UVLO protection circuit, ensuring that the system supply voltage will be within optimal operating range whenever in operation. This IC also provides a watchdog timer that is programmable from 4ms to 8s, which can be used to prevent system hangs, shut-downs, and help recover from errors or malfunctions.
The SM72240E/NOPB\'s working principle is based on a voltage-comparator and reset generator block, which compares a reference voltage generated internally with an input voltage. The comparator monitor\'s a pair of voltages, an upper-voltage threshold and a lower-voltage threshold. When the input voltage is above or below either of these thresholds, a reset output is sent to the system. This block also has an auto-recovery feature, which means the reset signal is automatically deactivated when the input voltage is within the preset range. This IC also has a power-on reset (POR) function, which is a reset pulse output immediately when the voltage is within the specified range during power-up.
The device also has a watchdog timer that functions based on an oscillator circuit. This circuit consists of two resistors and two capacitors to form an operational amplifier, with an adjustable timeout period provided by an external capacitor. This circuit is used to detect abnormality in the processor and can be used for functions such as providing a reset signal to the processor, in the event of a malfunction.
In conclusion, the SM72240E/NOPB is a very useful device that can be used to protect and reset systems from voltage faults when used in conjunction with other power management circuits. It has a variety of applications, ranging from PC and Mobile Platforms to applications with LDO linear regulators, PMICs and DC-DC converters. This device is also based on a simple principle, comparing two voltage thresholds with an input voltage and providing a reset signal when the input voltage is outside of the set parameters. In addition, it also has a watchdog timer that is customizable depending on the system requirements.
