PMIC—Supervisors, often abbreviated as PMIC, are a type of Integrated Circuit (IC) that helps manage power for circuits. The MAX6379UR37+T is a P-channel MOSFET and a MAX6379 supervisor integrated into the same chip for space-sensitive applications. It is known for its versatile, cost-effective, and convenient power control.

The application field of the MAX6379UR37+T ranges from industrial to commercial uses, such as automated test equipment, intelligent motor drives, solar-powered systems, and connected home products. Its versatility is evidenced by its wide operation temperature range (− 40°C to + 85°C), its low operating voltage range (1.8 V to 5.25 V), and its quick startup time of without requiring any additional circuitry or components.

The working principle of the MAX6379UR37+T is based on two main components: the P-Channel MOSFET and the MAX6379 supervisor. The P-Channel MOSFET is used to regulate and control currents on the load side of the load supply, and the MAX6379 supervisor is responsible for controlling the Power-On and Off operations, as well as providing power to the load, such as from a battery or from an AC supply.

The MAX6379UR37+T has a power-on response time of 50 ms. This helps ensure the quick start up time. Additionally, the MAX6379UR37+T is equipped with the open-drain RESET output (active low) and has an internal reset delay to activate the device for power-on reset (POR) protection. The delay can be adjusted by changing the external capacitor connected to TMS. Moreover, the MAX6379UR37+T comes with an adjustable UVLO threshold of 3.3V–3.6V, as well as a built-in delay of 15ms to avoid inadvertent and false triggering.

The MAX6379UR37+T also helps protect the system from surges and voltage drops. It is equipped with an integrated over-voltage protection (OVP) circuit and adjustable OVP levels ranging from 4.4V to 5.5V. Additionally, the MAX6379UR37+T also comes with an over-temperature protection (OTP) circuit. The OTP circuit can be configured to reset the device or to shut down the output without block the input voltage, helping systems remain safe in abnormal temperature conditions.

The MAX6379UR37+T is an efficient, reliable and affordable solution for managing power in space-sensitive applications. Its wide operation temperature range and its versatility in taking on different power supplies help ensure reliable performance of any power-sensitive system. In addition, the automatic shut down functions and built-in protection circuits make it a valuable option for any system.
