TLC7733M 具有可编程时间延迟的 3.3V 系统的单电源监控器
The TLC77xx family of micropower supply voltage supervisors provide reset control, primarily in microcomputer and microprocessor systems.
During power-on, RESET\ is asserted when VDD reaches 1 V. After minimum VDD ≥ 2 V) is established, the circuit monitors SENSE voltage and keeps the reset outputs active as long as SENSE voltage (VI(SENSE)) remains below the threshold voltage. An internal timer delays return of the output to the inactive state to ensure proper system reset. The delay time, td, is determined by an external capacitor:
td = 2.1 × 104 × CTWhere
CT is in farads
td is in seconds
Except for the TLC7701, which can be customized with two external resistors, each supervisor has a fixed SENSE threshold voltage set by an internal voltage divider
