2T09I50QDBVRG4Q Allgemeine Beschreibung

The TPS3809 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs and processor-based systems. The newer TLV809E device is an alternative with the same pins, functions and electrical parameters.

During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supervisory circuit monitors V_DD and keeps RESET active as long as V_DD remains below the threshold voltage V_IT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. The delay time, t_d(typ) = 200 ms, starts after V_DD has risen above the threshold voltage V_IT. When the supply voltage drops below the threshold voltage V_IT, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed sense-threshold voltage V_IT set by an internal voltage divider.

The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available in a 3-pin SOT-23. The TPS3809xxx-Q1 devices are characterized for operation over a temperature range of −40°C to 125°C, and are qualified in accordance with AEC-Q100 stress test qualification for integrated circuits.
