Smart Multi-Voltage Detector

General Description

Features

^zCapable of Monitoring Two Inputs Precisely

^zVCC Connect to 5V or 3.3V Standby Power

^zDetection Threshold Voltages

` V5 : 5V x 80%

The RT9823 is an integrated smart multi voltage detector

supervising two power supply voltage levels including 5V,

and another voltage (such as 3.3V or 12V) , which can be

set via an external resistive voltage divider.

` VADJ : 1V (Using Resistor Divider)

^zAccuracy : 2%

The RT9823 performs supervisory function by sending out

a CTR signal whenever the monitored voltages fall below

80% of the voltage levels. The CTR signal will last the

whole period before VCC recovers. Once the supervising

voltages are recovered to higher than 80% of the voltage

levels, the CTR signal will be released after a 300ms delay

time.

^zCTR (Open Drain Output Active Low)

^zBuilt-in Recovery Delay 300ms

^zManual CTR (MR) Function

^zSOT-23-6 Package

^zRoHS Compliant and Halogen Free

MR (Manual Reset) controls the CTR signal when the

two monitored power supply voltages are at normal voltage

levels. When the MR signal is in logic high, the CTR signal

will be pulled low immediately.

Applications

z LCD TV or Monitors

z Consumer Electronic Products

z System Voltage Detector

The RT9823 is available in a SOT-23-6 package.
