TPS3852H33DRBR

The TPS3852H33DRBR is a voltage supervisor integrated circuit (IC) manufactured by Texas Instruments. It is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold. Here’s a detailed description of its features and specifications:

Key Features:

1. Voltage Monitoring: The TPS3852H33DRBR monitors a supply voltage and generates a reset signal when the voltage drops below a predetermined threshold. This is crucial for ensuring that digital systems operate reliably and do not enter an undefined state during power fluctuations.

2. Adjustable Reset Threshold: The device features an adjustable reset threshold, allowing designers to set the voltage level at which the reset signal is triggered. This flexibility makes it suitable for a variety of applications.

3. Low Supply Current: The TPS3852H33DRBR is designed to operate with low supply current, which is beneficial for battery-powered applications where power efficiency is critical.

4. Fast Reset Response Time: The IC provides a fast response time to voltage changes, ensuring that the reset signal is generated quickly when the supply voltage drops below the threshold.

5. Active Low Reset Output: The reset output is active low, meaning that it goes low when a reset condition is detected. This is a common configuration that is compatible with many digital systems.

6. Temperature Range: The device operates over a wide temperature range, making it suitable for various environmental conditions.

7. Small Package Size: The TPS3852H33DRBR is available in a compact DRB package, which is a 5-pin SOT-23 package. This small form factor is ideal for space-constrained applications.

Electrical Specifications:

• Supply Voltage Range: The device typically operates within a supply voltage range of 1.0V to 5.5V.
• Reset Threshold Voltage: The reset threshold can be set to various levels, with the TPS3852H33DRBR specifically designed for a threshold of 3.3V.
• Reset Timeout: The reset signal remains active for a specified timeout period after the supply voltage returns to normal levels, ensuring that the system has stabilized before resuming operation.

Applications:

The TPS3852H33DRBR is suitable for a wide range of applications, including:

• Microcontroller and microprocessor reset circuits
• Power management systems
• Automotive electronics
• Industrial control systems
• Consumer electronics

Conclusion:

The TPS3852H33DRBR from Texas Instruments is a versatile and reliable voltage supervisor IC that provides essential monitoring and reset functionality for digital systems.
