• MR: Manual reset input (active low)
• RST: Reset output (active low)

Functional Features

• Power-on reset generation
• Monitoring of supply voltage
• Manual reset capability
• Adjustable reset timeout period
• Push-pull reset output

Advantages and Disadvantages

Advantages

• Wide supply voltage range
• Low quiescent current consumption
• Precision voltage threshold
• Small package size for space-constrained applications
