The SP690A by Signal Processing Technologies (SIG) is a low power microprocessor supervisory circuit. It is designed for 3.0V or 3.3V applications, offering a comprehensive solution for monitoring power-supply and battery-control functions in microprocessor-based systems. This integration significantly enhances system reliability and operational efficiency compared to discrete solutions.
Key features include a reset output with a time delay of 200ms, asserted down to 1V. It also incorporates a watchdog timer with a 1.6-second timeout to ensure system integrity. The device boasts a low VCC supply current of a maximum of 40 µA and a battery supply current of just 1 µA. Power switching capabilities include a 50mA output in VCC mode and 10mA in battery mode. A precision voltage monitor provides power-fail or low-battery warnings.
The SP690A is available in an 8-pin SOIC package suitable for surface mounting. It is pin-compatible with other supervisory circuits, offering upgrade possibilities. This component is ideal for portable electronics, computers, controllers, and intelligent instruments where reliable power supply monitoring is critical.
