Detailed Pin Configuration

The TPS3852G33QDRBRQ1 has the following pin configuration:

1. GND: Ground
2. RESET: Active-Low Reset Output
3. MR: Manual Reset Input
4. VDD: Supply Voltage

Functional Features

• Voltage Monitoring: The TPS3852G33QDRBRQ1 continuously monitors the supply voltage and asserts a reset signal when it falls below the programmed threshold.
• Manual Reset: The MR pin allows for manual resetting of the device, overriding the voltage monitoring function.
• Precision: The device offers accurate voltage monitoring with selectable threshold options.
• Low Power Consumption: With a quiescent current of only 7µA, the TPS3852G33QDRBRQ1 minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - Precise voltage monitoring ensures reliable system operation. - Low power consumption extends battery life in portable devices. - Manual reset capability provides flexibility in system control.

Disadvantages: - Limited threshold voltage options may not suit all applications. - The VSON package may require specialized assembly techniques.

Working Principles

The TPS3852G33QDRBRQ1 operates by comparing the supply voltage with a programmed threshold. When the supply voltage drops below the threshold, the device asserts a reset signal, indicating a power failure or an out-of-range condition. The manual reset input allows for user-initiated system resets, overriding the voltage monitoring function.

Detailed Application Field Plans

The TPS3852G33QDRBRQ1 finds application in various fields, including:

1. Automotive: Used in automotive electronic systems to monitor and reset microcontrollers, ensuring reliable operation and preventing system malfunction due to voltage fluctuations.
2. Industrial: Employed in industrial control systems to monitor power supplies and initiate system resets in case of voltage deviations, safeguarding critical processes and equipment.
3. Consumer Electronics: Integrated into consumer electronic devices such as smartphones and tablets to provide accurate voltage monitoring and ensure proper functioning under varying power conditions.
