Description and Introduction

25 The TPS3824-30DBVR is a voltage supervisor/manufacturer reset IC from Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS3824-30DBVR  
- **Type:** Voltage Supervisor with Watchdog Timer  
- **Reset Threshold Voltage:** 3.0V (fixed)  
- **Operating Voltage Range:** 1.7V to 6.5V  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms min)  
- **Watchdog Timeout:** Adjustable (1.6s typical)  
- **Output Type:** Active-low, push-pull  
- **Quiescent Current:** 5µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- Monitors system voltage and provides a reset signal if voltage falls below the threshold.  
- Includes a watchdog timer to detect microcontroller lock-ups.  
- Low power consumption makes it suitable for battery-powered applications.  

### **Features:**  
- Precision voltage monitoring (3.0V threshold).  
- Adjustable reset delay via external capacitor.  
- Built-in watchdog timer with adjustable timeout.  
- Low quiescent current (5µA typical).  
- Wide operating voltage range (1.7V to 6.5V).  
- Small SOT-23-5 package for space-constrained designs.  
- Industrial temperature range (-40°C to +125°C).  

This information is based solely on the provided knowledge base. No additional guidance or suggestions are included.

Alternative Part Number

  • MAX6746KA30+T --: Supervisory circuit with 3.0V threshold and watchdog in SOT-23-8, functionally similar to the TPS3824-30 in a comparable small package.
  • APX823-30W5G-7 --: Voltage supervisor with 3.0V reset threshold and watchdog timer, offered in SOT-25, suitable as a lower-cost functional replacement.
  • MCP1316MT-30AE/OT --: 3.0V watchdog voltage supervisor in SOT-23-5, providing reset and watchdog functions similar to the original device.
  • MAX6746KA-T --: Supervisory circuit with watchdog and manual reset in SOT-23, functionally similar to the TPS3824-30; verify reset threshold and active-low/high polarity before use.
  • MCP1316MT-30DI/OT --: 3.0V supervisor with watchdog and manual reset in SOT-23-5, offering comparable functionality as a cross-vendor replacement; confirm threshold tolerance and reset delay.
