Introduction

The MAX6865UK43D3S+T is a supervisor device that works as both a power-on reset (POR) and power supply supervisor (PSW) with an integrated digital temperature sensor. It is capable of providing active reset and enable signals for automotive and industrial systems. This device is ideal for battery-powered applications due to its low operating current requirements and active reset and enable signals. It is available in a 16-pin TSSOP package.

Applications

The MAX6865UK43D3S+T is a high-performance supervisor device that is well suited for use in automotive and industrial applications. These applications include advanced driver assistance systems (ADAS), engine control units (ECUs), sensors, powertrain modules and advanced safety systems. The device can also be used in other applications such as mobile phones, cameras, wearable devices, digital home appliances and various other consumer electronics.

Features

The MAX6865UK43D3S+T has several features that make it ideal for automotive and industrial applications. These features include active reset and enable signals, low operating current requirements, selectable reset and enable thresholds, power-on reset and reset filter time delay, temperature monitor, and a low power-off reset threshold. The maximum working temperature for the device is 105°C.

Working Principle

The MAX6865UK43D3S+T works by monitoring both the level of power supply ripple and the temperature. Whenever the measured voltage drops below the reset threshold voltage or the measured temperature rises above the temperature threshold, then the device will assert a reset signal. Additionally, the device has an enable pin that can be used to enable or disable the device. The MAX6865UK43D3S+T also has a filter time delay circuit that monitors the reset signal and prevents the device from resetting if the power supply voltage rises to the reset threshold voltage too quickly. This feature helps to protect system components by preventing the device from resetting too often, causing a potential system hang.

Conclusion

The MAX6865UK43D3S+T is a high-performance supervisor device that is well suited for use in automotive and industrial applications. This device can also be used in other applications such as mobile phones, cameras, wearable devices, digital home appliances and various other consumer electronics. It is capable of providing active reset and enable signals for automotive and industrial systems and has several features including low operating current requirements, selectable reset and enable thresholds, power-on reset and reset filter time delay, temperature monitor and a low power-off reset threshold. The device works by monitoring both the voltage and temperature levels and asserting a reset signal when the levels exceed the predetermined thresholds.
