The MAX6333UR16D3-T IC is a voltage supervisor designed for applications that require microprocessor system reset. It is classified as a PMIC (Power-management integrated circuit). It is designed to provide accurate and reliable power-on reset suppression and consists of low voltage detection, comparators and reset circuitry in a single mini-DIP or SO package. It is also available in temperature-grade, automotive and industrial grades.

The MAX633UR16D3-T IC can be used in a variety of applications. The IC is suitable for lowpowermicroprocessor, FPGA, ASIC, CPLD and system monitoring applications such as communication systems, automotive systems, industrial control systems, processors and peripherals that require precision reset and power-on reset suppression. It is also suitable for use in applications with different supply and reset active levels.

The device features a wide supply voltage range of 2.4V to 5.5V, and is capable of withstanding a wide input voltage range from 1V to 28V. The operating current is typically 6uA (5V supply voltage) and the standby current is 150uA (3V supply voltage). The device has a low monitoring voltage of 1.2V and an active reset voltage of 1.2V. It also has an adjustable reset delay time of 250ms to 4s and adjustable reset threshold of 5% or 7.5%. It supports reset voltage rising time of less than 1ms, and the reset threshold window is adjustable with a range of 1ms to 8.5ms.

The working principle of the MAX6333UR16D3-T IC is based on a window comparator. This comparator is designed to monitor a large window of input voltages and provide accurate and reliable shut-off or reset of power supplies. The device monitors the input voltage through two threshold inputs and when the voltage falls outside the specified window, an open drain RESET output is asserted. The RESET output can be used to provide a microprocessor reset. The device also has an active open drain EN (enable) output which allows a user to reset the device manually.

The MAX6333UR16D3-T IC offers a reliable and robust reset solution for microprocessor based circuits. The device offers an accurate window comparator, adjustable reset threshold and delay time, as well as a low input supply current. Its wide range of features makes it suitable for a variety of applications and environments, making it an ideal choice for power-on reset protection.
