DS1706PESA

Supervisors Overview

The DS1706PESA is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors voltage levels with thresholds of 3.3V and 5.0V. The device features an active low, push-pull output and includes manual reset capability. It incorporates a watchdog timer and power-fail detection. The maximum supply voltage is 5.5V, with a reset delay time of 285 ms. Operating current is 60 uA. The overvoltage threshold is 2.7 V. It operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Manual reset input for controlled recovery
• Power-fail warning detection capability

Supervisors Applications

• Voltage monitoring in embedded systems
• Supervisory circuits for microprocessor-based designs
• Power-fail detection in industrial equipment

Supervisors Procurement Notes

Verify the specific suffix and package variant against official datasheets, as the base model may have multiple configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected part matches the required voltage threshold and output polarity for the target application.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. Consider the 3.3V and 5.0V threshold options for compatibility with standard logic levels. Evaluate the 60 uA operating current for low-power applications. Verify that the SOIC-8 narrow package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MicroMonitor series from Maxim Integrated, designed for simple voltage supervision. It complements other devices like the DS1706SEUA and DS1706PEUA, which offer different packages and threshold variations. The series focuses on providing reliable reset generation and watchdog timing in a compact form factor.

Supervisors Replacement Considerations

DS1706PESA+T&R is a tape-and-reel variant of the same electrical specification. DS1706RESA+ offers alternative packaging. Verify pinout and electrical parameters before substitution.
