MAX825ZEXK+T Integrated Circuits (ICs)

The MAX825ZEXK+T is a voltage supervisor integrated circuit (IC) manufactured by Maxim Integrated. It is a version of the MAX825 series, which are based on field-effect transistor (FET) technology and provide multi-voltage monitoring and resetting capabilities in a simple and cost-effective package. This technology is commonly used in a wide range of applications such as embedded systems, communications, automotive, and industrial applications. The device is a member of the Power Management ICs (PMIC).

The MAX825ZEXK+T is a single-channel power supervisor with both power-on reset (POR) and brown-out reset (BOR) functions. It provides an adjustable BOR threshold voltage of 4.0V to 5.2V with a 2.8V to 6.4V input operating range. It also incorporates open-drain power-on reset (POR) with a trip level of 2.8V which is adjustable from 2.2V to 4.0V. It includes an active-low reset output pin with a one-time programmable reset delay, which can be set to delay the output of the reset pulse after a reset condition. The delay times can be set by a user via the I2C interface.

The MAX825ZEXK+T has several other features including a power-on reset hold-off function, a watchdog timer, and a window watchdog timer with a programmable timeout setting. It also allows for power sequencing and provides an active-low power-good output. It is available in a 5-pin SOT-23-5 package, making it suitable for space-constrained applications. The MAX825ZEXK+T is an ideal solution for applications such as embedded systems, communications, industrial, and automotive.

The MAX825ZEXK+T is designed to be used as a voltage supervisor in power applications. It is made up of transistors and passive components such as resistors and capacitors to monitor the supply voltage and generate a delayed reset output. When the input voltage to the device falls below the user-defined thresholds, a reset pulse is generated, which causes the connected circuit to reset itself. It also allows for power sequencing, which enables multiple power supplies to be turned on in a specific order.

The MAX825ZEXK+T can be used to provide power supply voltage protection, reset protection, and system protection for embedded systems, communications, automotive, and industrial applications. It can also be used to perform power sequencing, ensuring an orderly start-up of complex system designs. Its robust configuration and on-chip monitoring functions allow for reliable operation, even in the presence of an unstable power supply.

In summary, the MAX825ZEXK+T is an ideal single-channel power supervisor with power-on reset (POR), brown-out reset (BOR), and power-good features. It is suitable for a wide range of embedded systems, communications, automotive, and industrial applications. The device is user programmable and its on-chip monitoring functions allow for reliable operation, even in the presence of an unstable power supply.
