Description and Introduction

25 The TPS3823-33DBVT is a voltage supervisor from Texas Instruments. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 1.5V to 6.5V  
- **Threshold Voltage:** 3.08V (fixed for TPS3823-33 variant)  
- **Accuracy:** ±1.5% (typical)  
- **Quiescent Current:** 1.2µA (typical)  
- **Reset Timeout Period:** 200ms (minimum)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**
- The TPS3823-33DBVT is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold.  
- It is optimized for battery-powered and low-voltage applications.  
- The device features a manual reset input for external control.  

### **Features:**
- **Ultra-Low Power Consumption:** Ideal for battery-operated systems.  
- **Fixed Threshold Voltage:** No external components required for threshold setting.  
- **Manual Reset (MR) Input:** Allows external triggering of a reset.  
- **Open-Drain Reset Output:** Compatible with multiple logic levels.  
- **Power-On Reset Generator:** Ensures proper system initialization.  
- **Wide Operating Voltage Range:** Supports 1.5V to 6.5V.  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.  

This device is commonly used in microcontrollers, DSPs, FPGAs, and other embedded systems requiring reliable voltage monitoring.

Application Scenarios & Design Considerations

Alternative Part Number

  • MAX6746KA-T --: Supervisory circuit with 3.3V threshold and watchdog in SOT-23-5, functionally similar to the TPS3823-33 and pin-compatible in many designs.
  • APX823-33W5G-7 --: 3.3V voltage supervisor with watchdog in SOT-25, a direct functional replacement with similar threshold accuracy and reset timing.
  • MCP1316T-33CE/OT --: 3.3V supervisor with watchdog and manual reset in SOT-23-5, offering comparable features and a different series naming for easy distinction.
  • MAX6746KA29+T --: Supervisory circuit with 2.93V threshold and manual reset, functionally similar to the 3.3V TPS3823 in a small SOT-23 package.
  • APX803L-33SA-7 --: 3.3V voltage supervisor with active-low reset and open-drain output, a low-cost drop-in style alternative in SOT-23.
