Product Summary
The DS1706S is a microprocessor, for MicroMonitor monitors three vital conditions: power supply, software execution, and external override. A precision temperature compensated reference and comparator circuit monitor the status of VCC at the device and at an upstream point for maximum protection. When the sense input detects an out-of-tolerance condition, a non-maskable interrupt is generated. As the voltage at the device degrades, an internal power fail signal is generated which forcesthe reset to an active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for a minimum of 130 ms to allow the power supply and processor to stabilize.
Parametrics
DS1706S absolute maximum ratings: (1)Voltage Range on VCC Pin Relative to Ground: -0.5V to +7.0V; (2)Voltage Range on I/O Relative to Ground: -0.5V to (VCC + 0.5V); (3)Operating Temperature Range: -40°C to +85°C; (4)Storage Temperature Range: -55°C to +125°C; (5)Lead Temperature (soldering, 10s): +260°C; (6)Soldering Temperature (reflow)Lead(Pb)-free: +260°C.
