  • Use: Voltage Supervisor
  • Characteristics: Low Power, Reset Output, Adjustable Threshold
  • Package: SOT-23-5
  • Essence: Monolithic Voltage Supervisor Circuit
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.2V to 5.5V

  • Reset Timeout Period Options: 20ms, 140ms, 560ms, 1120ms
  • Operating Temperature Range: -40°C to +125°C

Detailed Pin Configuration

The TLV803MDBZT is a five-pin device with the following pin configuration:

  1. GND (Ground)
  2. MR (Manual Reset Input)
  3. VDD (Supply Voltage)
  4. RESET (Reset Output)
  5. NC (No Connection)

Functional Features

  • Monitors the supply voltage and asserts reset when it falls below the threshold.
  • Provides an adjustable reset threshold voltage to suit different applications.
  • Offers various reset timeout period options for flexibility.
  • Includes a manual reset input for external system control.

Advantages and Disadvantages

Advantages

  • Low power consumption, suitable for battery-powered devices.
  • Small package size allows for space-efficient designs.
  • Adjustable threshold and timeout options enhance versatility.
  • Manual reset input provides additional control.

Disadvantages

  • Limited number of available reset threshold voltage options.
  • No internal pull-up resistor on the manual reset input.

Working Principles

The TLV803MDBZT operates by continuously monitoring the supply voltage. When the voltage drops below the set threshold, the reset output is asserted, indicating a power failure or unstable voltage condition. The reset remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The TLV803MDBZT is commonly used in various applications, including:

  1. Microcontrollers: Ensures reliable system startup and prevents erratic behavior during power fluctuations.
  2. Industrial Control Systems: Provides voltage supervision to maintain stable operation of critical equipment.
  3. Automotive Electronics: Monitors the vehicle's electrical system to prevent malfunctions and ensure safety.
  4. Battery-Powered Devices: Protects against undervoltage conditions that can damage batteries or disrupt operation.

Detailed and Complete Alternative Models

  • TLV803MD: Similar specifications but available in a different package (SOT-23-6).
  • TLV803M: Fixed threshold voltage options with adjustable reset timeout periods.
  • TLV803S: Offers additional features like watchdog timer and power-on reset delay.
