MAX6334UR22D3-T is a PMIC - Supervisors device with advanced features and performance. It includes two functions for monitoring power supply voltages: voltage monitoring (VMON) and reset generation (RESET). The VMON monitors the voltage level at two user-programmable voltages, and the RESET can be triggered by either a user-programmable voltage level or an edge from a specific user-defined input.

MAX6334UR22D3-T provides an integrated solution for a variety of critical monitoring applications, such as over-voltage, and under-voltage protection, brown-out detection, power-on reset (POR) supervision, and manual reset. The device provides adjustable RESET and VMON thresholds, reset timing and unexpected power-on reset (UPR) feature. It also provides logic-level translation between voltage comparators and logic-level outputs.

The product is available in an ultrasmall, space-saving-5-lead SOT23 package and is designed to save system power and cost. The reset output is a power-on-reset (POR) signal that is asserted when the input voltage falls below a user-programmable voltage. The voltage monitoring (VMON) output is asserted when two user-selectable voltages are exceeded. The maximum output current is 10 mA for the RESET and VMON pins, so the outputs are very suitable for driving relays, LED, LCD backlighting, and device reset pins.

The product can be applied to a variety of supply voltages, ranging from 2V to 6.8V. It is configured to monitor power supply voltage levels in two ways: voltage monitoring (VMON) and reset generation (RESET). The VMON monitors two adjustable levels of the power supply voltage, while the RESET pin can be programmed to any voltage of a user-defined input, or it can be triggered by an edge in case of a brown-out. The reset threshold can be programmed individually to any voltage between 2V and 6.8V.

Moreover, the product can detect the presence of an over-voltage condition and protect integrated circuits from fatal damage. It detects UV And UVL voltages, as well as a manual reset initiated by a Fault Signal; and it monitors power-up sequencing sequences by using an external voltage divider between a reference voltage and a logic level threshold. The external voltage divider can be used to adjust the threshold levels to protect the output devices from fatal over-voltages, under-voltages or over-temperatures.

The MAX6334UR22D3-T is used in wide range applications, such as a data logging system, LCD / LED backlight control, industrial control, power rail supervisor, smart batteries, and portable electronics. It provides an ideal solution for saving system power and cost in low-voltage systems.

In conclusion, the MAX6334UR22D3-T is a high-performance power supply supervisor device for monitoring two adjustable power supply levels and providing user-defined reset generation. It is suitable for a variety of applications, from industrial control to smart batteries, and is an ideal solution for saving system power and cost. Its features and performance make it an attractive solution for many applications that require reliable power monitoring.
