MN13822SHP

Power management integrated circuit (PMIC) supervisors are a type of ICs used in electronic systems to provide power supply sequencing, power-on reset, and watchdog functions. The MN13822SHP is a PMIC supervisor IC designed with an on-chip voltage detector, countdown timer, POR (Power-On Reset), WS (Watchdog Supervision) and CS (Chip Supervision) functions. It is an ideal solution for applications such as digital cameras, tablets, industrial control, navigation systems, and personal computers.

The MN13822SHP is available in a small 4-pin TSOP-II package, making it suitable for space-constrained applications. The device operates from a single 2.5V to 5.5V power supply, offers selectable voltage detection thresholds, and can generate a power-on reset (POR) signal with a low starting voltage of 0.99V. This device also features an on-chip 5µs active filter that prevents false triggering of the watchdog timeout pulse. In addition, it features a timeout period of 1ms to 8.2s, and has an operating temperature range of -40°C to +125°C.

The MN13822SHP supervisor IC has a wide range of uses in a variety of power management and system protection applications. It is ideally suited for providing power-on reset, power failure detection, and reset timeout protection for portable electronic devices. In addition, its low operating voltage, selectable voltage detection thresholds, and active filter make it suitable for use in industrial control applications that require precision power supply management. Furthermore, it can be used to safeguard critical components from power surges and brownouts, and to prevent system crashes due to high temperature and power supply irregularities.

The MN13822SHP is able to provide the necessary functions for a wide range of power management and system protection applications. Its on-chip voltage detector can monitor the power supply voltage with a selectable thresholds, and generate a power-on reset (POR) signal when the voltage drops below a predetermined threshold. The device also features a low operating voltage of 0.99V, ensuring reliable power-on sequence. The on-chip active filter prevents false triggering of the watchdog timeout pulse, while its adjustable timeout period allows the user to set the desired timeout period.

The MN13822SHP can be used in a wide range of application fields, ranging from digital cameras and tablets, to industrial control and navigation systems, as well as personal computers. It ensures a reliable power-on sequence, and protects critical components from power surges and brownouts, as well as from system crashes caused by high temperature and power supply irregularities. The low operating voltage, selectable voltage detection thresholds, and trigger timeout period make it suitable for a variety of power management and system protection applications.
