MN13821SFP Integrated Circuits (ICs)

The MN13821SFP is a Power Management IC (PMIC) which belongs to the family of Supervisors. This device is contained in a small SSOP-20 package and can be applied in a variety of system-level power management applications.

The MN13821SFP is equipped with an array of functions including 5-bit Digital Voltage Detector (DVCC) with programmable detection voltage ranges, 6-bit Digital Programmable Threshold Circuit (PTC) with adjustable trip threshold voltages, Input Power Low Voltage Detect (IPD) with adjustable trip threshold, and a 2.3V to 5.5V adjustable linear regulator.

These features enable the MN13821SFP to be used for a variety of applications. It can be used for system power management in systems that require low voltage power supply monitoring and reset control. It is also ideal for multi-voltage power supply applications, battery-powered systems, and embedded systems.

Working Principle

The MN13821SFP is based on an embedded 5-bit Digital Voltage Detector (DVCC) and a 6-bit Digital Programmable Threshold Circuit (PTC). The DVCC detects the voltage levels at its input voltage inputs. The PTC monitors the level on its GPIO pin. The IPD monitors the level at the input power (VIN) and generates a reset (RST) signal when the input power is below the trip pin voltage threshold.

When the voltage at the DVCC input pins and the GPIO input pin exceeds their respective alert voltage thresholds, the DVCC and PTC generate a digital alert signal to the external programmable circuit. This digital alert signal triggers a reset or power on a circuit. In addition, when the input power level goes below a user programmable voltage, IPD generates a reset signal to the external circuit.

The output of the linear regulator is also monitored by a digital voltage detector. When the output voltage is above the warning voltage threshold, a digital alert signal is generated to turn off the regulator. This ensures that the system is not damaged by overvoltage.

Applications

The MN13821SFP can be used in a variety of applications. It is suitable for system power management in systems that require low voltage power supply monitoring and reset control. It is also ideal for multi-voltage power supply applications, battery-powered systems, and embedded systems.
