PT7A7514WEX

Introduction

The PT7A7514WEX is an ultra-small and low-power CMOS reset circuit with very low operating current. It is designed to provide a time-delayed reset of logic circuits when the power supply is switched on or off. The chip comprises a reset supervisor, a watchdog timer and two voltage detectors, providing protection for an embedded system from brown out and power supply conditions. It is well-suited for use in mobile systems, either as an independent reset supervisor circuit, or as part of an integrated power management or supervisory unit.

Application Field

The PT7A7514WEX reset circuit is ideal for use in embedded systems, personal computing systems and communications applications. Its ultra-low power consumption and very small package make it a great choice for low-power consumer electronic devices and mobile systems. The chip’s built-in watchdog timer and voltage detector circuits offer protection from unexpected events and power problems, while its small form factor allows it to be easily integrated into embedded systems.

Working Principle

The PT7A7514WEX reset circuit works in the following way: it contains a reset supervisor which constantly monitors the supply voltage and will generate an active-low reset when the voltage falls below the specified threshold. The reset supervisor also has a timeout feature to guard against any voltage errors. The chip also features a watchdog timer, which can reset the system in the event of a system malfunction or system lockout. Finally, the two voltage detector inputs can be used to monitor the system’s supply voltages, sending an active-low reset if the voltages exceed set thresholds.

Conclusion

The PT7A7514WEX reset circuit is an ideal choice for embedded systems, personal computing systems, and communications applications requiring a small, low-power reset circuit. Its built-in watchdog timer and voltage detector circuits offer protection from unexpected events and power problems, while its small form factor allows for easy integration into embedded systems. This reset circuit provides efficient and reliable protection for your embedded system and is a great choice for all your reset applications.
