Description and Introduction

Dual-Processor Supervisory Circuits with Power-Fail 8-SOIC -40 to 85 The TPS3306-15DRG4 is a power supply supervisor IC manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed threshold)  
- **Operating Voltage Range:** 1.8V to 6.5V  
- **Supply Current:** 15µA (typical)  
- **Reset Threshold Accuracy:** ±1.5% (over temperature)  
- **Reset Timeout Period:** Adjustable via external capacitor (default: 200ms)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- Monitors system voltage and provides a reset signal to the processor during power-up, power-down, or brownout conditions.  
- Features an active-low reset output with a push-pull configuration.  
- Includes a manual reset input for external control.  

### **Features:**  
- Precision voltage monitoring for 1.5V systems  
- Low quiescent current (15µA typical)  
- Adjustable reset delay time  
- Manual reset capability  
- Power-on reset generator  
- High noise immunity  
- Industrial temperature range support  

This IC is commonly used in embedded systems, microcontrollers, and other applications requiring reliable power monitoring.

Application Scenarios & Design Considerations

Dual-Processor Supervisory Circuits with Power-Fail 8-SOIC -40 to 85

Alternative Part Number

  • MAX6746KA29+T --: Dual-voltage supervisor with similar reset threshold and watchdog function, pin-compatible style SOT-23 package, direct functional replacement for supply monitoring applications.
  • ADM6316CY29ARJZ-R7 --: Single/dual voltage supervisor with adjustable reset timeout and manual reset, comparable threshold accuracy and low supply current, suitable drop-in for TPS3306-15 monitoring tasks.
  • MCP1316MT-29DI/OT --: Low-power voltage supervisor with watchdog and manual reset in SOT-23, similar threshold and timing behavior, cost-effective alternative for 1.5V/3.3V rail supervision.
