The MAX6385XS34D6-T is an advanced and economical power management IC (PMIC) designed to improve system reliability in complex industrial, automotive, and consumer electronic applications. This device is a specialized supervisor and voltage monitor designed to provide multiple supply supervision, system reset, and an overtemperature indicator signal. It is an integrated solution to inrush current limitation, power-on reset, supply voltage monitoring, output voltage tracking, and temperature monitoring functionalities.

The MAX6385XS34D6-T is designed to monitor a variety of input voltages and respond to a variety of conditions. It can be used to monitor and respond to input voltage, battery voltage, externally supplied voltage, and system temperature. It also provides reset outputs whenever any of the monitored voltages or temperatures fall outside of the predetermined levels. Additionally, it is capable of generating an indicating signal in response to a temperature threshold violation.

The device supports three power supplies: a 12V, 5V, and 3.3V input. The five POR/RESET outputs are designed to perform a one-time power-on reset when any of the input supply voltages has dropped below the specified threshold. Additionally, the device features an overtemperature indicator output that is activated when the TEMP pin voltage exceeds a predetermined level. The device also features a supervisory circuit that monitors the input voltage and signals a reset output when that voltage drops below a user-defined threshold.

The MAX6385XS34D6-T also includes several other features that can improve system reliability. It includes a digital voltage monitoring circuit that can monitor up to three supply voltages independently and provide a reset output if any of those voltages drops below a predetermined level. Additionally, it includes a temperature supervisor circuit that monitors the temperature pin voltage and responds with a reset output if it rises above a user-defined temperature threshold.

The MAX6385XS34D6-T also includes undervoltage and overvoltage protection circuits. The undervoltage protection circuit will monitor the supply voltage and detect when the voltage has fallen below the user-defined threshold, causing the reset output to be activated. The overvoltage protection circuit will detect when the supply voltage is above the specified threshold and disable the reset output, preventing the system from being reset.

Finally, the MAX6385XS34D6-T includes an adjustable delay circuit that is used to filter out short duration spikes in supply voltage that might otherwise cause false alarm reset outputs. This delay circuit can also be used to adjust the reset output duration when the reset output is activated.

In summary, the MAX6385XS34D6-T is an advanced and cost-effective PMIC that provides several features that can improve system reliability. It includes multiple supply supervision, reset output, overtemperature indicator output and additional features such as undervoltage and overvoltage protection and adjustable delay circuit. These features make it an ideal solution for industrial, automotive and consumer electronic applications.
