| Pin Number | Pin Name | Description | |------------|----------|-------------| | 1 | GND | Ground | | 2 | VDD | Supply Voltage | | 3 | RESET | Active-Low Reset Output | | 4 | TH | Threshold Voltage Selection | | 5 | MR | Manual Reset Input | | 6 | TR | Watchdog Timer Reset Input | | 7 | CT | Capacitor Connection for Reset Timing | | 8 | OUT | Output |

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below a certain threshold.
• Provides precision monitoring with selectable threshold voltage options.
• Offers manual reset capability through the MR pin.
• Includes a watchdog timer reset input for additional system protection.
• Low quiescent current consumption for power-sensitive applications.

Advantages and Disadvantages

Advantages: - Low-power operation extends battery life in portable devices. - Precision monitoring ensures reliable system performance. - Flexible threshold voltage options cater to various voltage levels. - Manual reset and watchdog timer reset inputs enhance system control and protection.

Disadvantages: - Limited number of threshold voltage options may not cover all application requirements. - The TSSOP-8 package may be challenging to solder for inexperienced users.

Working Principles

The TLC7705QPWR operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold, the RESET pin is driven low, indicating a system reset condition. The MR pin allows for manual reset, while the TR pin provides a watchdog timer reset function. The CT pin is used to connect an external capacitor for adjusting the reset timing.
