The LTC1235CS from Linear Technology is a sophisticated microprocessor supervisory circuit designed to manage power supplies and microprocessor activity. This component ensures reliable operation and protection for microprocessors by monitoring power supplies and providing essential control functions during power-up, operation, and power-down states.

Key Features:

• Power Monitoring: The LTC1235CS offers precision monitoring of +5V power supplies, providing a reset output during power-up, power-down, and brownout conditions.
• Reset Timeout: A built-in 200ms reset timeout guarantees a proper system reset, allowing enough time for the power supply and processor to stabilize before operation.
• Watchdog Timer: The integrated watchdog timer keeps systems running smoothly by requiring regular check-ins from the processor. If the processor fails to reset the watchdog timer within a preset time, the LTC1235CS will issue a system reset.
• Backup Battery Switchover: In the event of a power failure, an automatic backup battery switchover feature maintains power to the memory and real-time clock.
• Low Power Consumption: The device is optimized for low power consumption, making it an ideal choice for power-sensitive applications.

Applications:

• Microprocessor systems
• Computers and computer peripherals
• Embedded systems
• Intelligent instruments
• Portable battery-powered equipment

Technical Specifications:

• Supply Voltage Range: 4.75V to 5.5V
• Operating Temperature Range: 0°C to 70°C
• Packaging: 16-pin narrow SOIC
