PMIC - Supervisors: MN13821SUP Application Field and Working Principle

PMIC (Power Management Integrated Circuit) is an integrated circuit used to manage the power needs of different electronic devices. PMICs have many applications, such as for consumer and industrial applications, in communications and audio systems, for monitoring and controlling various sources of power and for powering light-emitting diode (LED) and other low-power devices. Supervisors are a special category of PMICs which specialize in running precision operations and maintaining a constant supply of power over longer periods of time.

MN13821SUP is a new member of the supervisory circuit family and designed to control power supply systems. It features a two-channel design, allowing two separate and independent outputs. The device operates in either open or closed loop. The open loop mode simply monitors the supply voltage and adjusts it to the target levels using an internal voltage reference. The closed loop mode is designed to monitor the output current and adjust it as needed. This makes it ideal for use in applications such as power supply system where it is important to maintain a constant output current.

The device is designed for low power applications, making it ideal for use in portable electronics. It comes in three versions: a 5V version, a 3.3V version and a 2V version. The output current is accurate to ±1% across the full input voltage range. It also has a selectable over-current protection threshold and it includes an integrated voltage reference and temperature compensation.

In terms of operation, the MN13821SUP can operate in either positive or negative loop operation. In positive loop operation, the device will monitor the output voltage and increase the voltage as necessary by drawing current from the supply. In negative loop operation, it will monitor the output current and reduce the voltage as necessary by drawing current from the load. This makes it suitable for a wide range of applications.

The device can be used to regulate many different types of power supplies, such as DC-DC converters, switched mode power supplies and switching buck converter. It is also suitable for use in high-temperature, low-voltage applications, such as automotive and industrial applications. The device is also capable of monitoring and controlling other types of loads, such as motors, LEDs and other low-power components.

The MN13821SUP is an extremely efficient and reliable device, making it an ideal choice for many different types of power management solutions. Its low power consumption makes it an ideal choice for portable electronics, while its precision and robustness make it suitable for a wide range of different applications.
