PT7M6101CHTA5E, classified as PMIC - Supervisors, is a device that monitors power supply voltage and provides a reset signal to the system when this falls below a pre-defined threshold. Additionally, PT7M6101CHTA5E also features a watchdog timer, adjustable reset threshold and reset delay, as well as monitoring input power. This device is specifically designed for low-power applications, such as those in battery-powered products or embedded systems.

Applications

PT7M6101CHTA5E is applicable in a variety of applications that require a low-power solution for power supply monitoring and resetting, such as cell phones, portable Bluetooth devices, medical devices, and other low-power applications. In particular, PT7M6101CHTA5E is ideal for mobile/wireless systems that operate on a single cell battery, as the integrated low-voltage comparator and watchdog timer enable a reset signal to be generated in the event of low-battery voltage or loss of power. Additional applications include portable handheld systems, digital still cameras and personal digital assistants.

Working Principle

PT7M6101CHTA5E is designed to provide over-voltage protection and reset control functionalities in a low-power consumption single chip. It features a low-voltage comparator that is programmed with a reset threshold of 2.0V. When the voltage of the power supply drops below this threshold, the low-voltage comparator triggers the reset signal by sending out a reset pulse to the system. The reset duration is adjustable from 10ms up to 655.35s. PT7M6101CHTA5E also contains an integrated watchdog timer, allowing for watchdog functionality without the need for additional external components. When the timer reaches its timeout value, the low-voltage comparator sends a reset pulse to the system, providing effective reset control.

PT7M6101CHTA5E can also operate in power-down mode, reducing power consumption to approximately 10uA. This allows the reset control device to enter a power-saving state when the system is in standby. Furthermore, the low-voltage comparator can be bypassed when the system runs with a voltage higher than the preset reset threshold, eliminating unnecessary power consumption.

Conclusion

PT7M6101CHTA5E can provide an effective and reliable low-power solution for a variety of applications, including cell phones, medical devices, portable handheld systems, and digital still cameras. The device contains an integrated low-voltage comparator, watchdog timer, and adjustable reset delay, enabling reset control and over-voltage protection for low-power applications. Additionally, the device provides a power-down mode for additional power savings, allowing for effective power management of the system.
