XC6121 TOREX [Torex Semiconductor], XC6121 Datasheet - Page 3

• Manufacturer Part Number: XC6121
• Description: Voltage Detector with Watchdog Function and ON/OFF Control (VDF=1.6V~5.0V)
• Manufacturer: TOREX [Torex Semiconductor]

■PRODUCT CLASSIFICATION
●Selection Guide
●Ordering Information
* Please set the release delay time shorter than or equal to the watchdog timeout period.
* EN input logic: The watchdog function turns on when the EN pin becomes high level.
* ENB input logic: The watchdog function turns on when the ENB pin becomes low level.
ex.) XC6121D327MR or XC6121D627MR
