TPS3828-33QDBVRQ1

Схема контроля напряжения, ручной сброс, активный низкий, сброс с открытым стоком, 1.1В-5.5В (Vin).

The TPS3828-33QDBVRQ1 is a Supervisor Circuit with active-low open-drain output. The supervisor provides circuit initialization and timing supervision, primarily for DSP and processor-based systems. During power on, /RESET asserts when the supply voltage VDD becomes greater than 1.1V. Thereafter, the supply voltage supervisor monitors VDD and keeps /RESET active low 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.
