RT9824C
Smart Multi-Voltage Detector
General Description
The RT9824C 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 RT9824C 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 60ms 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 RT9824C is available in the TSOT-23-8 package.
