A PMIC - Supervisors is a type of power management integrated circuit designed to serve as a supervisory chip in an electronic circuit, used in almost all digital systems. One of these is the MAX6375UR23+T, a high-accuracy voltage supervisor designed to operate with dual power-supply systems. This integrated circuit has a wide range of applications and its workability depends on a variety of important factors such as its headroom, input voltage range, temperature accuracy, and more.

Features of MAX6375UR23+T

The MAX6375UR23+T is a high-precision voltage supervisor which features a wide operating voltage range from 1.5V to 6V, with a guaranteed 0.3% accuracy. It also offers excellent headroom and a fast 600ns typical detection latency. With a wide temperature range of -40°C to +85°C, its operation remains stable throughout any extreme temperatures and its full-temperature accuracy is guaranteed over the entire range. The MAX6375UR23+T contains two voltage monitors as well as two active-low reset output pins that have an adjustable time delay to ensure reliable reset operation during power-up and power-down sequences.

Working Principle of MAX6375UR23+T

The MAX6375UR23+T uses a voltage divider to send a reference voltage to its comparator, which compares it against an input voltage. If the input voltage is below the reference voltage, the comparator output goes low and triggers the reset output. If the input voltage is higher than the reference voltage, the comparator output goes high and the reset output stays inactive. The MAX6375UR23+T also has internal hysteresis to prevent the reset output from oscillating. In order to ensure reliable reset operation during power-up and power-down sequences, an adjustable reset time delay is provided. This delay is set by an external capacitor connected to the “delay” pin. The delay period is defined by the equation TD =1.1 x Cd x Rd where Cd is the value of the external capacitor in Farads and Rd is the value of the external resistor in ohms.

Applications of MAX6375UR23+T

The MAX6375UR23+T is ideal for use in computers and notebooks, serving as a power supervisor for monitoring core voltage, memory voltage, 3.3V/5V/12V/etc. The MAX6375UR23+T is also useful for applications such as computer servers, workstations and other systems that require high accuracy and fast response for their voltage monitoring and reset outputs.

The MAX6375UR23+T can also be used in a variety of other applications such as, industrial controllers, telecommunications and network equipment, automotive electronics and more. The low operating current and wide input range of the MAX6375UR23+T make it perfect for battery-operated systems. Also, its internal hysteresis and adjustable reset time delay provide reliable reset signals and prevent false triggering.

Conclusion

The MAX6375UR23+T is a high-accuracy and reliable voltage supervisor integrated circuit designed to serve as a power supervisor and reset circuit in many digital systems. With its wide operating voltage range, fast 600ns typical detection latency, and high accuracy, the MAX6375UR23+T is suitable for use in a wide variety of applications, from computers and notebooks to industrial controllers and automotive electronics. The internal hysteresis and adjustable reset time delay also make it ideal for battery-operated systems.
