LDD3352-20-PF - Brand New LIGITEK IC Chips
-
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
