TPS3805H33 单路电压检测器
TPS3805H33 描述
The TPS3803 and TPS3805 families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSPs and processor-based systems.
The TPS3805H33 device has a fixed-sense threshold voltage VIT set by an internal voltage divider, whereas the TPS3805H33 has an adjustable SENSE input that can be configured by two external resistors. In addition to the fixed sense threshold monitored at VDD, the TPS3805 devices provide a second adjustable SENSE input. RESET is asserted in case any of the two voltages drops below VIT.
During power on, RESET is asserted when supply voltage VDD becomes higher than 0.8 V. Thereafter, the supervisory circuit monitors VDD (and/or SENSE) and keeps RESET active as long as VDD or SENSE remains below the threshold voltage VIT
