Product Introduction

Overview

The TPS3824-50DBVR is a voltage monitor with a watchdog timer from Texas Instruments, part of the TPS382x family. This component is designed to provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. It ensures proper system reset by monitoring the supply voltage and asserting a reset signal when the voltage drops below a predefined threshold. The device is available in a 5-pin SOT-23 package and operates over a temperature range of -40°C to 85°C.

Key Specifications

Parameter Description Value
Package SOT-23 (5-pin) 2.90 mm × 1.60 mm
Supply Voltage (VDD) Monitored voltage 2.5 V, 3 V, 3.3 V, 5 V
Threshold Voltage (VIT-) Negative-going input threshold voltage 4.46 V to 4.64 V (for 5V option)
Watchdog Time Out Time out period for watchdog timer 1.6 seconds
Delay Time (td) Reset delay time after VDD rises above threshold 120 ms to 300 ms
Manual Reset (MR) Input to force a reset Pull low to force reset
Reset Output Type of reset output Active-low or active-high, push-pull or open-drain
Operating Temperature Temperature range for operation -40°C to 85°C

Key Features

  • Supply Voltage Monitoring: Monitors the supply voltage and asserts a reset signal when the voltage drops below the predefined threshold voltage (VIT-).
  • Watchdog Timer: Offers watchdog time out options of 1.6 seconds to ensure system integrity.
  • Manual Reset: Allows an external logic signal to force a reset regardless of the supply voltage or watchdog timer state.
  • Active-High or Active-Low Output: Provides both active-high and active-low reset output options, either push-pull or open-drain.
  • No External Components Required: The device uses an internal voltage divider to set the threshold voltage, eliminating the need for external components.

Applications

  • DSP and Processor-Based Systems: Primarily designed for digital signal processors and microprocessor-based systems.
  • Notebook and Desktop Computers: Suitable for use in notebook and desktop computers to ensure proper system reset and watchdog functionality.
  • Industrial Equipment and Programmable Controls: Used in various industrial applications and programmable control systems to monitor and manage power supply voltages.

Q & A

  1. What is the primary function of the TPS3824-50DBVR?

    The primary function is to monitor the supply voltage and provide a reset signal when the voltage drops below a predefined threshold, ensuring proper system initialization and timing supervision.

  2. What are the available supply voltage options for the TPS3824-50DBVR?

    The device can monitor supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V.

  3. What is the watchdog time out period for the TPS3824-50DBVR?

    The watchdog time out period is 1.6 seconds.

  4. How does the manual reset feature work on the TPS3824-50DBVR?

    The manual reset feature allows an external logic signal to force a reset by pulling the MR input low, regardless of the supply voltage or watchdog timer state.

  5. What types of reset outputs are available on the TPS3824-50DBVR?

    The device provides both active-high and active-low reset output options, which can be either push-pull or open-drain.

  6. Do I need external components to set the threshold voltage for the TPS3824-50DBVR?

    No, the device uses an internal voltage divider to set the threshold voltage, so no external components are required.

  7. What is the operating temperature range for the TPS3824-50DBVR?

    The operating temperature range is -40°C to 85°C.

  8. In what package is the TPS3824-50DBVR available?

    The device is available in a 5-pin SOT-23 package.

  9. What are some common applications for the TPS3824-50DBVR?

    Common applications include DSP and processor-based systems, notebook and desktop computers, and industrial equipment.

  10. How does the reset delay time work on the TPS3824-50DBVR?

    The reset delay time (td) starts after the supply voltage (VDD) rises above the threshold voltage (VIT- + VHYS), ensuring proper system reset.
