TPS3828-33 Processor Supervisory Circuit

TI TPS3828-33 processor supervisory circuit provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power-on, RESET asserts when the supply voltage VDD becomes higher than 1.1V. After that, the supply voltage supervisor monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time, td, starts after VDD has risen above the threshold voltage, VIT−. When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. This device has a fixed-sense threshold voltage, VIT–, set by an internal voltage divider.

  • Power-On Reset Generator With Fixed Delay Time of 200ms (TPS3823/4/5/8) or 25ms (TPS3820)
