Smart Multi-Voltage Detector

General Description

Features

^zCapable of Monitoring Three Inputs Precisely

^zDetection Threshold Voltages

` VCC Connect to 5V or 3.3V Standby Power

` V5 : 5V x 80%

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.

` V54 : 5.4V x 80%

The RT9824 performs supervisory function by sending out

RESETand 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.

` VADJ : 1V (Using Resistor Divider)

^zAccuracy : 2%

^zRESET (Open Drain Output Active Low)

^zBuilt-in Recovery Delay 300ms

^zCTR (Open Drain Output Active Low)

^zManual Reset (MR) Function

^zTSOT-23-8 Package

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.

z RoHS Compliant and Halogen Free

Applications

z LCD TV or Monitors

z Consumer Electronic Products

z System Voltage Detector

The RT9824 is available in the TSOT-23-8 package.
