The newer TLV809E device is an alternative with the same pins, functions and electrical parameters. • • 3-pin SOT-23 package Supply current of 9 μA (typical) Precision supply voltage monitor 2.5 V, 3 V, 3.3 V, 5 V Pin-for-pin compatible with MAX 809 Temperature range:  –40°C to +85°C During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the supervisory circuit 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(typ) = 200 ms, 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. All the devices of this family have a fixed sense-threshold voltage VIT set by an internal voltage divider. 2 Applications • • • • • • • Factory automation Wireless speakers Motor drives Servers Appliances Electricity meters Building automation 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 TPS3809 devices are characterized for operation over a temperature range of –40°C to 85°C.

RESET 2 O RESET is an active low signal, asserting when VDD is below the threshold voltage. When VDD rises above VIT, there is a delay time (td) until RESET deasserts. RESET is a push-pull output stage. VDD 3 - Supply voltage pin.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
