Description and Introduction

3.0V/3.3V Low Power Microprocessor Supervisory Circuits The SP706SCN is a microprocessor (μP) supervisory circuit manufactured by SIPEX (now part of Microchip Technology). Below are the factual details about this part:

### **Specifications:**
1. **Voltage Monitoring:** Monitors 5V, 3.3V, and 3V power supplies.
2. **Reset Threshold Accuracy:** ±1.5% (typical).
3. **Reset Timeout Period:** Adjustable (typically 200ms).
4. **Operating Voltage Range:** 1V to 5.5V.
5. **Manual Reset Input:** Includes a debounced manual reset input.
6. **Watchdog Timer:** Features an independent watchdog timer with a 1.6s timeout (adjustable).
7. **Power-On Reset (POR):** Guarantees a reset pulse upon power-up.
8. **Low Quiescent Current:** Typically 35μA (with watchdog disabled).
9. **Temperature Range:** Industrial (-40°C to +85°C).
10. **Package:** 8-pin SOIC or PDIP.

### **Descriptions:**
- The SP706SCN is designed to monitor power supply voltages and provide a reset signal to the microprocessor if the voltage falls below a preset threshold.
- It ensures reliable system operation by preventing erratic behavior during power-up, power-down, or brownout conditions.
- The watchdog timer monitors software execution and triggers a reset if the system fails to respond within the set timeout period.
- The manual reset input allows for user-initiated system resets.

### **Features:**
- **Precision Voltage Monitoring:** Ensures accurate reset thresholds for stable operation.
- **Adjustable Watchdog Timer:** Configurable timeout period for flexibility.
- **Low Power Consumption:** Suitable for battery-powered applications.
- **Industrial-Grade Reliability:** Operates across a wide temperature range.
- **Compact Package Options:** Available in surface-mount (SOIC) and through-hole (PDIP) packages.

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

3.0V/3.3V Low Power Microprocessor Supervisory Circuits

Alternative Part Number

  • MAX706SCSA --: Pin-compatible supervisory IC with the same reset threshold and functions, widely used as a direct substitute for the SP706 series.
  • ADM706SARZ --: Equivalent microprocessor supervisory circuit offering reset and watchdog functions with matching threshold, suitable drop-in replacement.
  • IMP706SCPA --: Alternative supervisory IC with comparable reset threshold and features, commonly cross-referenced for SP706 designs.
  • IMP706SCSA --: Drop-in replacement supervisory IC with identical pinout and threshold, commonly used as a lower-cost alternative to the SP706 series.
  • MAX706SCSA+ --: Pin-compatible supervisory circuit with the same reset threshold and functions, widely available and a direct functional drop-in for the SP706.
