Application field

The PT7M6101NLTA5EX is best suited to mission-critical systems where ultra-high reliability and precision are paramount. It is used in a wide range of applications such as in medical and industrial control systems, automotive sensors, photovoltaic systems, and audio-video components. It can also be used in a variety of power supplies and other power management systems where securing system reliability and accuracy is essential.

Working principle

The PT7M6101NLTA5EX implements a Precision Voltage Supervision (PVS) system, which monitors the system\'s power supply voltage. The device measures the voltage against programmed voltage thresholds, then provides the appropriate reset signal depending on the monitored voltage levels. The reset signal is an active open drain output, compatible with a wide range of logic voltage levels and semiconductor technologies. The reset active level is configurable and may be set as active high or active low.

The Watchdog Timer (WDT) monitors the system\'s health via a separate timer input. This timer is active when the WDT is triggered. An active timer output is provided when the WDT expires. Depending on the timing and the application, the timer output may be configured to act as a reset, interrupt, or vertical sync signal. The timeout period is adjustable using the external cap TIMR pin, allowing users to adjust the timeout period to match the desired application.

The PT7M6101NLTA5EX\'s accuracy and precision are enhanced by the use of advanced sensing and self-calibration techniques. True precision is ensured by the device\'s ±30 mV monitoring margin, as well as ±1.25% accuracy across all temperature ranges.

Overall, the PT7M6101NLTA5EX is a reliable solution for mission-critical applications requiring precision voltage supervision and watchdog timer functions. Its accurate, dependable performance, along with its adjustable viewing margin and flexible logic signals, make it the perfect solution for your precision voltage monitoring and watchdog timer needs.
