ADM6823TYRJZ-RL7

ADM6823 is a low voltage, supervisory circuit with watchdog and manual reset. This low voltage, supervisory circuit that monitors power supply voltage levels and code execution integrity in microprocessor-based systems. As well as providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by means of an external push-button through a manual reset input. Typical applications are microprocessor systems, computers, controllers, intelligent instruments, portable equipment.

• Precision low voltage monitoring, power supply glitch immunity
• Watchdog timer with 1.6sec timeout (typical)
• Manual reset input, reset output stage, push-pull active-low
• VCC operating voltage range from 1 to 5.5V (VCC=2.7V to 3.6V, TA=–40°C to +125°C)
• Supply current is 20µA max (WDI and MR unconnected, VCC=5.5V, VCC=2.7V to 3.6V, TA=–40°C to +125°C)
• 3.08V reset threshold, 140ms reset timeout
• Reset threshold temperature coefficient is 60ppm/°C typ (VCC=2.7V to 3.6V, TA=–40°C to +125°C)
• Watchdog timeout period is 2.4sec max (VCC=2.7V to 3.6V, TA=–40°C to +125°C)
• Temperature rating range from -40°C to +125°C
• 5-lead SOT-23 package
