Description and Introduction

Low Quiescent Current, Programmable-Delay Supervisory Circuit The TPS3808G15DBVR is a voltage supervisor (reset IC) manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 1.8V to 6.5V  
- **Threshold Voltage Options:** Fixed (1.5V for TPS3808G15DBVR)  
- **Reset Timeout Period:** Adjustable (via external capacitor) or fixed (200ms typical)  
- **Quiescent Current:** 1.1µA (typical)  
- **Output Type:** Active-low, push-pull  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS3808G15DBVR is a low-power voltage supervisor designed to monitor system voltages and provide a reset signal when the voltage falls below a preset threshold (1.5V in this case). It ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.  

### **Features:**  
- **Ultra-Low Power Consumption:** Ideal for battery-powered applications.  
- **Adjustable or Fixed Reset Delay:** Configurable via an external capacitor.  
- **Wide Operating Voltage Range:** Supports 1.8V to 6.5V.  
- **Small Package:** SOT-23-5 for space-constrained designs.  
- **High Accuracy Threshold:** Ensures reliable monitoring.  
- **No External Components Required:** For fixed-delay operation.  

This device is commonly used in microcontrollers, DSPs, and other digital systems requiring reliable power monitoring.

Application Scenarios & Design Considerations

Low Quiescent Current, Programmable-Delay Supervisory Circuit

Alternative Part Number

  • MAX6715AUTTD3+T --: Supervisory circuit with similar reset threshold and open-drain/push-pull output options, pin-compatible SOT23-6 package, good drop-in alternative for supply monitoring.
  • APX803L-15SA-7 --: Low-cost voltage supervisor with 1.5V threshold and manual reset, SOT23 package, functionally equivalent for reset generation in embedded designs.
  • MCP1316T-15CE/OT --: Voltage supervisor with 1.5V trip point and manual reset input in SOT23-5, offers comparable reset timing and low quiescent current.
  • MCP1316T-15DI/OT --: Voltage supervisor with 1.5V trip point and manual reset, SOT-23-5 package, offers similar monitoring function from a different vendor.
