PMIC - Supervisors are a type of integrated circuit that provide protection to system components on a circuit board from overvoltage, undervoltage, overcurrent, and short-circuit events. One such PMIC Supervisor is the MIC809MUY-TR. This integrated circuit offers low quiescent current, dependable supply voltage regulation, and overcurrent protection for a variety of applications.

The MIC809MUY-TR is designed to provide precise OVP and OCP control of high power output circuits, with a low quiescent current of only 5μA in the UVLO mode, compared to regular OV Field Supervisors with quiescent current in the hundreds of μA. Furthermore, its Over Voltage Protection (OVP) and Over Current Protection (OCP) features are integrated into one tiny 8-Lead SOIC package. It is specifically designed to monitor a 5V to 36V input range, and offer adjustable OVP and OCP thresholds.

The MIC809MUY-TR also features independant two-color LED indication and a RESET pin that can be driven programmably as an active low open collector output or with a simple toggle output. These features bring added flexibility for detection and control applications.

The MIC809MUY-TR\'s working principle is based on the instantaneous overvoltage or overcurrent conditions. This triggers the RESET pin to activate, and returns the circuit output to its normal operating state or turns the system off depending on the setting of the RESET pin. The OVP and OCP conditions can be independently programmed, much like a programmable watchdog timer, to provide the most reliable protection, minimizing the number of false shut downs.

The application field of the MIC809UY-TR is incredibly diverse. Any device that requires external shutdown protection and control can benefit from using this device. Some of the most common areas of application include:

• Cellular phones
• Fax machines
• Portable and cordless phones
• Portable computers
• Point of Sale terminals
• LCD TVs
• DVD players
• Digital cameras

The MIC809MUY-TR is also often used in industrial applications such as motor control and DC-DC converters. In motor control systems, the device provides quick shutdown in the event of an overcurrent. In DC-DC converters, it allows the output regulators to be shut down when an over voltage occurs at the output, thereby avoiding any potential damage to devices connected downstream.

The MIC809MUY-TR is a simple, yet reliable and cost-effective solution for protecting various system and power components from voltage and current overshoot. It offers a dependable overvoltage and overcurrent protection, adjustable OVP and OCP thresholds, and two-color LED indication. All these features make the MIC809MUY-TR an ideal choice for a wide range of applications.
