TSOT-23-8 Smart Multi-Voltage Detector Features Capable of Monitoring Three Inputs Precisely Detection Threshold Voltages VCC Connect to 5V or 3.3V Standby Power V5 : 5V x 80% V54 : 5.4V x 80% VADJ : 1V (Using Resistor Divider) Accuracy : ±±±±±2% RESET (Open Drain Output Active Low) Built-in Recovery Delay 300ms CTR (Open Drain Output Active Low) Manual Reset (MR) Function TSOT-23-8 Package RoHS Compliant and Halogen Free Applications LCD TV or Monitors Consumer Electronic Products System Voltage Detector General Description The RT9824 is an integrated smart multi-voltage detector supervising three power supply voltage levels including 5V, 5.4V and additional 3.3V, 12V or other voltage which can be determined by external divided resisters. The RT9824 performs supervisory function by sending out RESET and CTR signals whenever the monitored voltages fall below 80% of voltage levels. The RESET and CTR signals will last the whole period before VCC recovering. Once the supervising voltages are recovered to higher than 80% of the voltage levels, the RESET and CTR signal will be released after 300ms delay time. MR (Manual Reset) controls CTR signal during three monitored power supply voltages at normal voltage levels. When MR signal is in logic high, the CTR signal will be pulled low immediately. However the RESET will not be interfered and will be kept at high level. The RT9824 is available in the TSOT-23-8 package. 5 34 6 8 2 7 Marking Information AF= : Product Code DNN : Date Code AF=DNN Package Type J8 : TSOT-23-8 Lead Plating System G : Green (Halogen Free and Pb Free) RT9824 |
