Description and Introduction

3.0V/3.3V Low Power Microprocessor Supervisory Circuits The SP706SEP is a microprocessor (μP) supervisory circuit manufactured by SIPEX. Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Supply Voltage Range:** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (1.8V, 2.32V, 2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (minimum)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** 8-pin SOIC, 8-pin PDIP  

### **Descriptions:**  
- The SP706SEP monitors system power supply voltages and provides a reset signal to the microprocessor during power-up, power-down, or brownout conditions.  
- It includes a watchdog timer (WDT) to detect software malfunctions and trigger a reset if not cleared within a set time.  
- The manual reset input allows for external reset control.  

### **Features:**  
- **Power-On Reset (POR) Generator:** Ensures proper system initialization.  
- **Watchdog Timer:** Prevents system lock-up (1.6s timeout default).  
- **Manual Reset Input:** Allows user-initiated reset.  
- **Low Quiescent Current:** Typically 35μA (at 3.3V).  
- **Brownout Detection:** Protects against voltage drops.  
- **Push-Pull or Open-Drain Reset Output:** Configurable based on model variant.  

This information is based solely on the manufacturer's datasheet for the SP706SEP.

Application Scenarios & Design Considerations

3.0V/3.3V Low Power Microprocessor Supervisory Circuits

Alternative Part Number

  • MAX706SEPA+ --: Pin-compatible supervisor IC with the same reset threshold and watchdog functions, widely available and a direct functional drop-in.
  • ADM706SARZ --: Equivalent microprocessor supervisory circuit with matching reset and watchdog features in an 8-pin package, suitable as a second-source replacement.
  • IMP706SEPA --: Low-cost pin-compatible supervisor with similar reset threshold and watchdog timing, commonly used as a substitute for the SP706 series.
