The SP706 is a CMOS supervisory circuit manufactured by Sipex Corporation. It's designed to monitor voltage levels in digital systems and provide a reset signal when the voltage drops below a certain threshold. This helps to prevent data corruption and ensures reliable system operation.

Applications

• Microprocessor systems: Reset generation for microprocessors and microcontrollers.
• Memory systems: Voltage monitoring for memory devices.
• Power supplies: Overvoltage and undervoltage protection.
• Embedded systems: System monitoring and reset control.
• Portable devices: Battery voltage monitoring.

Features

• Precision voltage monitoring: Accurate voltage threshold detection.
• Power-on reset generation: Generates a reset signal at power-up.
• Watchdog timer: Monitors microprocessor activity and generates a reset if the processor fails to respond within a specified time.
• Low power consumption: Minimizes power drain in battery-powered applications.
• Small package size: Compact footprint for space-constrained designs.
• Active-low reset output: Reset signal is active low.

Benefits

• Improved system reliability: Prevents data corruption and ensures proper system initialization.
• Simplified design: Reduces the need for external reset circuitry.
• Low power consumption: Extends battery life in portable devices.
• Space saving: Small package size allows for use in compact designs.
• Cost-effective: Provides a reliable and affordable solution for voltage monitoring.

Additional Details

The SP706 monitors a single voltage level. The reset threshold voltage is pre-set. The watchdog timer monitors the activity of a connected microcontroller or processor. The SP706 is typically available in a small surface-mount package. Refer to the Sipex datasheet for detailed electrical characteristics, timing diagrams, and application notes. Proper decoupling capacitors should be used to minimize noise and ensure stable operation. This part is now manufactured by Exar which acquired Sipex.
