Essence: The TCM811LERCTR is a low-power supervisor IC designed to monitor the voltage level of a power supply and provide a reset signal to the system when the voltage falls below a specified threshold.

Packaging/Quantity: The TCM811LERCTR is available in a SOT-23-3 package, with 3000 units per reel.

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Reset Threshold Voltage: 2.93V (typical)
  • Manual Reset Input Voltage: 0.8V (min), VCC (max)
  • Power-On Reset Delay Time: 100 ms (typical)
  • Quiescent Current: 1.5 µA (typical)
  • Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TCM811LERCTR has three pins:

  1. VCC: Power supply input pin.
  2. GND: Ground reference pin.
  3. MR: Manual reset input pin.

Functional Features

  • Voltage Monitoring: The TCM811LERCTR continuously monitors the voltage level of the power supply.
  • Reset Output: When the voltage falls below the specified threshold, the active-low reset output is asserted.
  • Manual Reset Input: The manual reset input allows for an external reset signal to be applied, overriding the voltage monitoring function.
  • Power-On Reset Delay: The TCM811LERCTR provides a power-on reset delay of 100 ms (typical) to ensure stable operation during power-up.

Advantages and Disadvantages

Advantages: - Low power consumption - Small package size - Wide supply voltage range - RoHS compliant

Disadvantages: - No adjustable reset threshold voltage - Limited number of pins for additional functionality

Working Principles

The TCM811LERCTR operates by comparing the voltage level at the VCC pin with a fixed threshold voltage. When the voltage falls below the threshold, the active-low reset output is asserted, indicating a power failure or an out-of-tolerance condition. The manual reset input allows for an external reset signal to override the voltage monitoring function.

Detailed Application Field Plans

The TCM811LERCTR can be used in various applications where voltage monitoring and system reset functionality are required. Some potential application fields include:

  1. Battery-Powered Devices: The low-power consumption of the TCM811LERCTR makes it suitable for battery-powered devices that require efficient voltage monitoring and system reset capabilities.
  2. Embedded Systems: The IC can be utilized in embedded systems to ensure proper operation and prevent data corruption in case of power supply fluctuations.
  3. Industrial Control Systems: The TCM811LERCTR can be employed in industrial control systems to monitor the power supply and provide a reliable reset signal to maintain system integrity.

Detailed and Complete Alternative Models

Some alternative models to the TCM811LERCTR that offer similar functionality are:

  1. TCM809LERCTR: Low Power Supervisor with Fixed Threshold Voltage and Manual Reset Input.
  2. TCM803LERCTR: Low Power Supervisor with Adjustable Threshold Voltage and Manual Reset Input.
  3. TCM802LERCTR: Low Power Supervisor with Fixed Threshold Voltage and Active-High Reset Output.

These alternative models provide options for different threshold voltages and reset output configurations, allowing flexibility in design choices.
