Package

The TPS2101DBVR is available in a small SOT-23 package.

Essence

The essence of the TPS2101DBVR lies in its ability to ensure stable and reliable voltage levels in electronic systems, preventing damage or malfunction due to voltage fluctuations.

Packaging/Quantity

The TPS2101DBVR is typically packaged in reels, with 3000 units per reel.

Specifications

• Supply Voltage Range: 1.8V to 6.5V
• Threshold Voltage Options: Adjustable from 0.9V to 5.5V
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TPS2101DBVR has three pins:

1. VCC: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground reference.
3. RESET: This pin outputs a low signal when the monitored voltage falls below the threshold level.

Functional Features

• Accurate voltage monitoring: The TPS2101DBVR ensures precise monitoring of the input voltage.
• Adjustable threshold voltage: The threshold voltage can be set according to the specific requirements of the system.
• Power-on reset: The device generates a reset signal upon power-up, ensuring a controlled start-up sequence.
• Manual reset: A manual reset option allows for system restarts when required.

Advantages and Disadvantages

Advantages

• Provides reliable voltage supervision, preventing damage to sensitive components.
• Adjustable threshold voltage allows for customization based on system requirements.
• Low quiescent current consumption helps conserve power in battery-operated devices.
• Small package size enables usage in space-constrained applications.

Disadvantages

• Limited number of threshold voltage options may not cater to all voltage monitoring needs.
• Lack of built-in hysteresis may result in oscillations near the threshold voltage.

Working Principles

The TPS2101DBVR operates by comparing the input voltage with the set threshold voltage. When the input voltage falls below the threshold level, the RESET pin outputs a low signal, indicating a voltage fault condition. The device continuously monitors the voltage and generates a reset signal until the voltage rises above the threshold level.

Detailed Application Field Plans

The TPS2101DBVR finds application in various electronic systems that require voltage monitoring and supervision. Some potential application fields include:

1. Power supply units: Ensuring stable voltage levels in power supplies to protect downstream components.
2. Battery-powered devices: Monitoring battery voltage to prevent over-discharge and extend battery life.
3. Microcontrollers: Providing a controlled start-up sequence and protecting against voltage fluctuations.
4. Industrial automation: Monitoring voltage levels in control systems to maintain operational stability.
5. Automotive electronics: Protecting sensitive automotive components from voltage variations.
