Pin Configuration

The TLV810RDBZR is a 3-pin device with the following pinout:

1. GND (Ground)
2. VDD (Supply Voltage)
3. RESET (Active-Low Reset Output)

Functional Features

• Monitors the supply voltage and asserts the reset output when it falls below the threshold voltage.
• Provides precision monitoring with selectable threshold voltage options.
• Offers an adjustable or fixed reset timeout period for flexibility in system design.
• Low quiescent current consumption ensures minimal power usage.
• The active-low push-pull reset output can directly drive various loads.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with different systems. - Precision monitoring helps ensure reliable operation. - Adjustable or fixed reset timeout period offers flexibility in system design. - Low quiescent current consumption minimizes power usage. - Active-low push-pull reset output can drive various loads.

Disadvantages: - Limited to 3-pin SOT-23 package, which may not be suitable for all applications. - Output current limited to 10mA, which may not be sufficient for certain loads.

Working Principles

The TLV810RDBZR operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold voltage, the device asserts the active-low reset output. The reset output remains asserted until the supply voltage rises above the threshold voltage and the reset timeout period elapses. This ensures proper system initialization and prevents erratic behavior during power-up or voltage fluctuations.

Detailed Application Field Plans

The TLV810RDBZR is commonly used in a wide range of applications, including but not limited to:

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