RT9824C pdf资料下载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.Datasheet pdf资料数据表下载
