The MAX6834HXRD4+T is a PMIC supervisor device used to detect and monitor the operating voltage of various systems, as well as support advanced system system reset functions. This device comes in a 4-pin ultra-small form factor and is specifically tailored to offer a variety of advanced features. This product allows system designers to easily optimize performance, reduce power consumption, and save board space.

The MAX6834HXRD4+T offers the best-in-class advanced monitoring capabilities for a wide range of system voltages including 1.71V, 1.8V, 2.5V, 2.7V and 3.3V. It can identify and detect faults reliably at 0.95V and detect a full power-on reset with a range of 1.985V from 1.9V to 3.86V. This device is optimized to detect external power supply faults and system faults at the same time, and can detect a minimum voltage drop of 0.95V and a maximum voltage drop of 0.3V. It is also typically used to monitor a system’s operating voltage and battery backup voltage levels.

The MAX6834HXRD4+T manages system reset functions via an internal push-button, an external external push-button, an in-system non-volatile memory reset, and a system reset. It can also drive a reset pulse in response to special reset conditions such as a battery reset and a power on reset. When the reset function is enabled, this device can generate a low voltage reset pulse in response to an external push-button or a low voltage warning event. The reset pulse is adjustable between 1ms and 80ms.

MAX6834HXRD4+T provides additional features such as supply and telemetry monitoring, low voltage warning, and low voltage reset. This device can monitor the input voltage of a system, and generate a low voltage warning if the voltage drops below a preset threshold. The low voltage warning can be programmed to generate a reset pulse or set an interrupt for system recovery, in the case of an low voltage threshold event. It also has a supply monitor, which can be set to monitor the system’s operating voltage, and generate an interrupt if the voltage drops below a certain level. Additionally, MAX6834HXRD4+T provides an in-system memory reset, which can be triggered by a low voltage warning.

The MAX6834HXRD4+T also supports telemetry inputs, LED blink sequence, and port pins that can be used as primary sources of information. Telemetry inputs can be used to send status information back to the system, such as system reset, low voltage reset, low voltage warning, and other logic levels. LED sequences can be used for status indication, in order to provide visual feedback to the user. The MAX6834HXRD4+T also supports port pins that can act as control lines or can be used to interface with other system components.

MAX6834HXRD4+T is commonly used in applications such as NAND flash memory and multi-core processors. It is also used in industrial, automotive, wearable, and IoT systems. This device is designed to provide an advanced, cost-effective solution to ensure the availability, stability, and operational efficiency of a wide range of system applications.
