Working Principles

The MAX16057ATT21+T is designed to monitor the voltage level of a power supply and provide a reset signal when the voltage falls below a certain threshold. The threshold voltage can be selected using the TH pin, allowing flexibility in different applications.

When the voltage drops below the threshold, the RESET# pin goes low, indicating a reset condition. The reset timeout period can be adjusted using an external capacitor connected to the CT pin. This allows customization of the time delay before the reset signal is released.

In addition to the automatic reset function, the MR pin provides a manual reset input. When this pin is pulled low, it immediately triggers a system reset, regardless of the voltage level.

Detailed Application Field Plans

The MAX16057ATT21+T finds applications in various fields where voltage monitoring and reset functionality are required. Some potential application areas include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Power management circuits
4. Battery-powered devices
5. Industrial control systems
