The MAX16072RS29D0+T is a robust Power-supply Supervisory integrated circuit (IC) designed to monitor and protect the circuits that require low-voltage supplies. With its regulating design and construction, this device will provide a comprehensive portfolio of features and capability. The features range from wide input voltage ranges, current sourcing and sinking, output voltage trimming, supply sequencing and a watchdog timer.

This integrated circuit is particularly suitable for embedded systems and controllers where up to five power supplies must be monitored for accurate and reliable operation. It also has high accuracy for minimum voltage set point detection, fast propagation delay and low-power consumption. All these features together make the MAX16072RS29D0+T an ideal IC for system designers.

The MAX16072RS29D0+T comes in a tiny 16-pin surface-mount small-outline-integrated-circuit (SOIC) package and operates over an extended temperature range of -40°C to +125°C. It has an adjustable precision voltage monitoring and delivers two open-drain outputs that provide a reliable active-low or open-drain outputs.

The operating voltage of the MAX16072RS29D0+T is between 1.2V and 3.3V, making it suitable for low-voltage applications. The typical current draw for the device is about 15\xB5A, making it very efficient for power management. The watchdog timer has a time-out period of up to 1.2ms, providing a debounce time of 0.2ms. It can detect voltages as low as 0.47V.

The MAX16072RS29D0+T features a low-temperature-compensated, low-current power-on reset (POR) circuit, with a safe-state voltage reference to ensure an accurate threshold voltage, even in the presence of temperature and supply-voltage variations. The POR circuit offers an active-low reset signal during startup and a reset flag after VCC rises above the detection voltage. It also has an output tolerant of up to 10mA within 10V, which is useful for powering external devices or circuits during brownout.

The MAX16072RS29D0+T has a brownout detection circuit that provides an active-low reset signal when the power supply voltage drops below the detection voltage. The brownout detector operates in either static or dynamic mode, and also supports dual-supply configurations. The device also features an integrated watchdog timer that can be used for system timeout management. It includes an open-drain output for a reset signal when the watchdog time-out is reached.

The MAX16072RS29D0+T also offers an external voltage reference output, which is used to bandgap another device for accuracy and stability. This feature is beneficial when the system requires precision voltage monitoring. The integrated low-voltage detector also has a programmable open-drain output for a selectable voltage trip point. This detection point is adjustable, which allows users to set the alarm to their desired threshold.

The MAX16072RS29D0+T provides an ideal solution for embedded systems and controllers requiring power-supply monitoring and supervision. With its wide input voltage range, excellent accuracy, fast propagation delay, and low power consumption, this device offers high performance, reliability, and flexibility in applications such as motor controls, medical devices, communication systems, and industrial/automotive electronics. The MAX16072RS29D0+T gives system designers the capability to implement increasingly complex power supply architectures to work reliably and with less energy in a competitive market.
