Description
The LDD3352-20-PF is an electronic component model in the product category of IC Chips. It is an ultra-low-voltage microprocessor supervisory circuit designed to monitor two or three system power-supply voltages. This device asserts a system reset if any monitored supply falls below its factory-trimmed or adjustable threshold and maintains reset for a minimum timeout period after all supplies rise above their thresholds. It significantly improves system reliability and reduces size compared to separate ICs or discrete components.
Specifications and features
• VCC1 (Primary Supply) Reset Threshold Voltages from 1.58V to 4.63V
• VCC2 (Secondary Supply) Reset Threshold Voltages from 0.79V to 3.08V
• Externally Adjustable RSTIN Threshold for Auxiliary/Triple-Voltage Monitoring (0.62V Internal Reference)
• Watchdog Timer Option - 35s (min) Long Startup Period, 1.12s (min) Normal Timeout Period
• Manual-Reset Input Option
• Power-Fail Input/Power-Fail Output Option (Push-Pull and Open-Drain Active-Low)
• Guaranteed Reset Valid Down to VCC1 or VCC2 = 0.8V
• Reset Output Logic Options
• Immune to Short VCC Transients
• Low Supply Current 14µA (typ) at 3.6V
• Watchdog Disable Feature
• Small 5-, 6-, and 8-Pin SOT23 PackagesApplication Scenarios
