Detailed Pin Configuration

TLV803RDBZR features three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that provides a reset signal to the monitored system.

Functional Features

1. Voltage Monitoring: TLV803RDBZR continuously monitors the supply voltage and asserts the reset signal when it falls below the specified threshold.
2. Manual Reset Input: It allows an external signal to assert a reset condition, overriding the voltage monitoring.
3. Power-On Reset Delay: TLV803RDBZR ensures a stable power supply before releasing the reset signal during power-up.

Advantages and Disadvantages

Advantages

• Low-power consumption makes it suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Adjustable reset threshold voltage provides flexibility in different voltage monitoring scenarios.

Disadvantages

• Limited number of reset threshold voltage options.
• Lack of additional advanced features compared to some other voltage supervisors.

Working Principles

TLV803RDBZR operates by comparing the supply voltage with the set threshold voltage. When the supply voltage drops below the threshold, the reset signal is asserted. The manual reset input can override this functionality. During power-up, a delay ensures a stable power supply before releasing the reset signal.

Detailed Application Field Plans

TLV803RDBZR finds application in various fields, including but not limited to: - Embedded systems - Industrial automation - Consumer electronics - Automotive electronics - Internet of Things (IoT) devices
