MAX6324FUT29-T

MAX6324FUT29-T supervisors are an integrated circuit solution developed by MAXIM Integrated. This device is designed to prevent the system from short-circuiting or overvoltage or excessive power supply or increase in current load and other conditions that may occur during the application field. In particular, it is intended for use in electronic systems with a voltage bias range of 3.15V to 18V as a supervisor. MAX6324FUT29-T provides comprehensive system protection with industry-leading power supply and temperature capability.

The MAX6324FUT29-T supervisor integrates industry-leading power supply and temperature protection and extreme reliability while minimizing component count and area. It includes both an adjustable voltage trip and a fixed voltage trip that can be used to detect system-critical fault conditions such as over-voltage, under-voltage, over-current, and over-temperature conditions. In addition, two threshold voltage trip settings can be used to support over-voltage/under-voltage protection applications. The device also provides a windowed reset output signal that is used only when the voltage or temperature exceed preset trip points.

The MAX6324FUT29-T also offers a wide temperature range operation (-40°C to +125°C) for reliable operation in harsh environments, making it suitable for many power supply and system applications. Built-in over-voltage protection prevents unexpected over-voltage surges from damaging internal components. On-board OVP (Over-Voltage Protection) circuitry allows for a smooth recovery from the fault condition in moments.

MAX6324FUT29-T also includes a two-level reset output (RST1 and RST2) with both active-low and active-high output. The active-high RST1 output can be used to drive a power-on reset (POR) signal and the active-low RST2 output can be used to drive a system reset signal. The supervisory block also includes a power-good (PG) signal indicating when normal supply voltage has been recognized. The low voltage and temperature conditions can be monitored via selectable POR/PG/RST outputs on an external bus, specifically for cases when normal POR/PG/RST signals are not provided for the application.

The MAX6324FUT29-T device is designed to meet stringent security requirements to protect from unauthorized access or manipulation of critical system parameters. It is designed with a built-in hardware-based Watchdog timer (WDT) to assure maximum system uptime and reliability. An open collector output on the MAX6324FUT29-T activates and assert a WDT signal during detection of any system fault or when the WDT is reset. In addition, the WDT can generate an Autonomous Reset as a fail-safe mechanism in instances when the system fails to respond to initial reset attempts. This ensures uninterrupted operation of the system, while guaranteeing that critical applications remain operational.

MAX6324FUT29-T also supports many of the most powerful and now essential system-level standby operation modes to ensure that a system can remain powered down while still being kept updated with critical data. It supports deep sleep (power-down) modes, managed stand-by used to save power while keeping system data and authorization keys alive, and hibernation (no-power) modes used in end products like black-box devices or similar systems.

In conclusion, the MAX6324FUT29-T supervisors offer a comprehensive set of features for optimized system protection in a variety of applications with industry leading power supply and temperature capabilities. With critical features such as overvoltage, undervoltage, over-current, over-temperature protection, Watchdog timer, improved reset signaling and autonomous reset, this device is designed to provide superior system uptime and reliability.
