Maxim Integrated 1 Voltage Supervisor 1.2V - 5.5V Surface-Mount 8-Pin SO DS1705ESA+

Maxim Integrated DS1705ESA+ is a highly accurate voltage supervisor designed to protect microprocessor circuits by monitoring supply voltage and issuing resets during undervoltage or transient power conditions. The device supports one supervisor channel and includes a watchdog timer to monitor system operation. It operates within a supply range of 1.2V to 5.5V, making it compatible with a range of 3.3V and 5V systems.

Housed in a compact 8-pin Small Outline (SO) surface-mount package, the DS1705ESA+ facilitates space-saving PCB designs. The unit’s reset active time of 285 milliseconds ensures stable microprocessor restart after power interruptions, preventing erratic microprocessor behavior. It supports both active high and active low output driver configurations, enhancing flexibility for system integration.

Designed for industrial-grade applications, the device operates over a wide temperature range from -40°C to 85°C and does not require external discrete components, simplifying the design process. Its pin-compatible design allows seamless replacement of MAXIM MAX705/MAX706 supervisors across DIP, SO, and μSOP packages.

This voltage supervisor is ideal for embedded systems, industrial electronics, power management circuits, and other applications requiring high-reliability reset supervision for microprocessor control. It supports pushbutton monitoring for external reset override.

Includes one voltage supervisor channel with watchdog timer. Surface mount 8-pin SO package for compactness and ease of placement. Supply voltage range between 1.2V and 5.5V supporting varied system voltages. Reset active time of 285ms for reliable system recovery post power failure.

Wide industrial temperature range from -40°C to +85°C. Active high and active low output to suit different system logic levels. Pin-compatible with MAXIM MAX705/MAX706 family for easy upgrade paths. Eliminates external discrete components reducing BOM and circuit complexity.
