The MAX6834VXRD0+T supervisor is a programmable device used to monitor, reset and detect power-supply irregularities and system faults. It is found in various applications such as communications, embedded systems, portable electronics, high-end industrial, computer, and automotive electronics. The MAX6834VXRD0+T monitors power supply rails, system events and signals, and then controls the resetting of these power supply rails and systems. This device also provides watchdog timer functionality and an integrated power on reset (POR) functionality for a reliable system reset. The MAX6834VXRD0+T supervisor is a great choice for mission-critical applications that require board-level monitoring and reset from a single package.

The MAX6834VXRD0+T supervisor has two different types of pins, Input and Output. All input pins are connected to the voltage supply, creating a monitored voltage domain. These pins are used to monitor the system’s operating conditions and detect irregularities. Moreover, the supervisor can be used for many different tasks, like tracking the pulse width modulated signals that are sent to the microcontroller, detecting an under-voltage situation, monitoring a system’s current draw, or detecting a system reset. Output pins provide feed-back on system status, triggering a reset if any of the monitored conditions are not met.

The MAX6834VXRD0+T offers a wide range of programmable functions such as adjustable reset/clear thresholds, adjustable reset/clear time delays, adjustable delay delay timers, open-drain reset/clear outputs, open-drain power-on reset output, watchdog timer, MOSFET control, and current sense. In addition, it is equipped with two programmable power subsystems, one for the reset functionality and the other for the watchdog timer functionality.

The MAX6834VXRD0+T supervisor offers a highly programmable reset and watchdog timer for critical applications. It provides adjustable reset/clear thresholds and can detect voltage drops down to 0.8V. It offers adjustable reset/clear time delays for precise timing control and an adjustable delay timer for reset/clear sequencing. The MAX6834VXRD0+T supervisor allows for programmable triggering of reset/clear outputs and features an open-drain power-on reset output to ensure a valid reset of the system.

Apart from the reset/clear outputs, the MAX6834VXRD0+T supervisor also offers a dedicated MOSFET control output. This output can be used to turn on/off powered ICs without the need to control the device’s voltage supply, while also providing an easy way to adjust the supply current limits and ensure a safe operation in case of system faults.

The MAX6834VXRD0+T supervisor also supports current-sense output. This monitor allows the system to track its current draw and detect high-level and low-level faults. The MAX6834VXRD0+T supervisor can detect faults even when the voltage supply is at a low voltage level and interrupt the power supply when the threshold is reached. This feature helps protect against short circuits or overloading.

The MAX6834VXRD0+T supervisor can be used in a variety of applications, from communications to embedded systems, from portable electronics to high-end industrial and automotive electronics. Its wide range of programmable functions and its ability to monitor, reset, and detect power-supply irregularities and system faults make it a great choice for mission-critical applications, providing board-level monitoring and reset from a single package.
