• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The DS1833Z-10 has three pins:

1. VCC: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin provides the reset signal to the system.

Functional Features

• Voltage Monitoring: The DS1833Z-10 continuously monitors the power supply voltage.
• Reset Generation: When the voltage falls below the set threshold, it generates a reset signal to the system.
• Adjustable Threshold: The reset threshold voltage can be adjusted using external resistors.
• Power-On Reset: It provides a reset signal during power-up to ensure proper initialization of the system.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring
• Low power consumption
• Wide operating voltage range
• Adjustable reset threshold
• Small package size

Disadvantages

• Fixed reset timeout period
• Limited availability in alternative packages

Working Principles

The DS1833Z-10 works by comparing the power supply voltage with the set threshold voltage. If the voltage drops below the threshold, it triggers the reset signal. The reset signal remains active until the voltage rises above the threshold or the reset timeout period elapses.
