Power management IC (PMIC) – Supervisors are a type of integrated circuit used in modern electronics. These ICs provide the logic and power supervision in systems where multiple devices have to be managed by one control logic. This type of electronic circuit serves to enhance the performance, simplify the design, reduce the power consumption and extend the battery life of electronic products.

LM809M3-4.63/NOPB is a power management integrated circuit that belongs to the PMIC – Supervisors category. It is used as a reset supervisor circuit, providing low power active reset control to the system. The LM809M3-4.63/NOPB offers two-level reset protection to the system by integrating with a delay delay reset output and an active-low, power-good active reset output, which asserts when VCC falls below the reset threshold voltage.

The LM809M3-4.63/NOPB integrates a reference voltage, a comparator and a flip-flop. The reference voltage is set by an external resistor, which is connected to the voltage VCC and ground. The comparator compares the VCC voltage with the output of the reference voltage. When the VCC voltage is lower than the reference voltage, the comparator output asserts a logic low. This logic low is latched by the flip-flop, which then asserts a logic low power reset state. This condition remain until the VCC voltage is above the reference threshold and the power reset state is negated.

The LM809M3-4.63/NOPB also provides a reset delay output. When VCC falls below the reset threshold voltage, the reset delay output will assert a logic high for a preset time determined by an external capacitor connected to the delay pin. This delay time allows for power to be restored to the system, before the reset output is negated. This reset delay time is inversely proportional to the external capacitor value.

The LM809M3-4.63/NOPB is used in many electronic systems, such as computers, telecommunications devices, gaming consoles and automotive electronics. It is ideal for use in systems where there is a need to detect power and voltage status, as well as providing active reset control to the system. The two-level reset protection and the reset delay makes it a versatile and reliable supervisor IC.

In conclusion, LM809M3-4.63/NOPB is an integrated circuit that belongs to the PMIC – Supervisors category. It is mainly used to detect the power and voltage status and provide active reset control to the system. It provides two-level reset protection and reset delay output for better system performance. The LM809M3-4.63/NOPB is widely used in various electronic systems due to its reliability and versatility.
