Introduction

MAX6307UK35D4-T is a microprocessor supervisory circuit that can monitor up to four independent supply voltages. It is designed to provide an accurate and reliable reset signal for microprocessors, DSPs and other complex electronic systems. It provides fully adjustable active-low and active-high reset thresholds and has a proprietary Dual-Pulse reset assert function to eliminate damage due to short-term output glitching. This supervisory circuit provides reset signals with a TTL/CMOS compatible open-drain output and offers a variety of reset options to cover most microprocessor/DSP reset requirements.PMIC - SupervisorsPMIC (Power Management Integrated Circuit) supervisors are specialized circuits designed to monitor and control power supplies. They work by monitoring the voltages supplied to the system\'s power supplies, and if any of these voltages fall below the threshold set in the chip\'s programming, the supervisor will send a signal to the reset switch, which in turn will shut down the power. This allows the system to save its system state, so that it can be restarted without loss of data or any system-level problems. The MAX6307UK35D4-T is a PMIC supervisor designed to monitor up to four different system voltages independently, and provides an additional active-high and active-low reset signal for microprocessors, DSPs and other digital components. It contains a proprietary Dual-Pulse reset capability which allows the chip to generate a reset signal in two steps, ensuring that the system can save its vital state in case of a short-term output glitching. The MAX6307UK35D4-T supervisor also offers a variety of reset options to cover most microprocessor/DSP reset requirements.

Performance and Features

The MAX6307UK35D4-T supervisor is a low-power voltage supervisor with high-precision voltage monitors with high-accuracy reset thresholds and reset sequence. It has an operating voltage range of 4.5V to 5.5V. This device comes with several features, including: • Proprietary Dual-Pulse reset assert function to ensure that the system can save its vital state in case of a short-term output glitching. • Active-Low and Active-High reset, for maximum flexibility • TTL/CMOS compatible open-drain reset output. • Internal watchdog timer. • Voltage Monitor Accuracy of ±2.5%. • Over-Voltage Shutdown (OVSD) feature for protecting against transient over-voltage events.• Temperature range of -40℃ to +125℃. • Low supply current consumption.

Applications

The MAX6307UK35D4-T supervisor is designed to be used in a wide range of applications. It is most suitable for microprocessor-based systems, where precision and reliability are key factors. It is also highly suitable for embedded systems, providing effective and reliable reset and power management. The MAX6307UK35D4-T is also ideal for use in applications that require a watchdog timer, such as medical and automotive systems.

Working Principle

The MAX6307UK35D4-T supervisor works by individually monitoring up to four power supplies with its high-accuracy voltage monitors. If any of these voltages fall below the threshold set in its programming, the supervisor will send a signal to the reset switch that will shut down the power. The MAX6307UK35D4-T also has a TTL/CMOS compatible open-drain output and offers a variety of reset options to cover most microprocessor/DSP reset requirements. The supervisor also features a proprietary Dual-Pulse reset capability which allows the chip to generate a reset signal in two steps, ensuring that the system can save its vital state in case of a short-term output glitching. The OVSD (Over-Voltage Shutdown) feature allows the device to protect against transient over-voltage events, while the internal watchdog timer can be used to keep the system running at optimal levels.

Conclusion

The MAX6307UK35D4-T is a highly reliable, high-accuracy microprocessor supervisory circuit that can monitor up to four independent supply voltages. It provides fully adjustable active-low and active-high reset thresholds and has a proprietary Dual-Pulse reset assert function to eliminate damage due to short-term output glitching. This supervisory circuit provides reset signals with a TTL/CMOS compatible open-drain output and offers a variety of reset options to cover most microprocessor/DSP reset requirements. It is suitable for a wide range of applications that require precision, reliability, and power management features, such as embedded systems, medical systems, and automotive systems.
