1. Description
TPS3823-33DBVTG4 series monitor provides circuit Initialization and timing supervision, mainly used for DSP And processor-based systems. During power-up, When the power supply voltage VDD Becomes greater than 1.1 V. After that, the power supply Voltage monitor monitors VDD and keeps RESET As long as VDD stays below Threshold voltage, VIT-. An internal timer delay The output returns to the inactive state (high) to Ensure proper system reset. Delay time, td, Start When VDD rises to the threshold voltage (VIT−+ VHYS). When the power supply voltage is lower than Threshold voltage VIT−, the output becomes active (Low) Again. No external components are required. All This series of equipment has a fixed meaning Threshold voltage, VIT– , Set by internal voltage Divider. TPS382x series also provide watchdog 200 ms (TPS3820) and 1.6 s timeout options (TPS3823/4/8).
