description (continued)

During power-on, RESET is asserted when supply voltage V becomes higher than 1.1 V. Thereafter, the

supply voltage supervisor monitors V and keeps RESET active as long as V remains below the threshold

voltage V . An internal timer delays the return of the output to the inactive state (high) to ensure proper system

IT−

reset. The delay time, t , starts after V has risen above the threshold voltage V . When the supply voltage

IT−

drops below the threshold voltage V , the output becomes active (low) again. No external components are

IT−

required. All the devices of this family have a fixed-sense threshold voltage V set by an internal voltage

IT−

divider.

The TPS3820/3/5/8 devices incorporate a manual reset input, MR. A low level at MR causes RESET to become

active. The TPS3824/5 devices include a high-level output RESET. TPS3820/3/4/8 have a watchdog timer that

is periodically triggered by a positive or negative transition at WDI. When the supervising system fails to retrigger

the watchdog circuit within the time-out interval, t , RESET becomes active for the time period t . This event

tout

also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog.

In applications where the input to the WDI pin may be active (transitioning high and low) when the

TPS3820/3/4/8 is asserting RESET, the TPS3820/3/4/8 does not return to a non-reset state when the input

voltage is above Vt. If the application requires that input to WDI is active when RESET is asserted, WDI must

be decoupled from the active signal. This can be accomplished by using an N-channel FET in series with the

WDI pin, with the gate of the FET connected to the RESET output as shown in Figure 1.

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 5-pin SOT23-5 package. The TPS382x-xxQ 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.

⁽²⁾Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability

information and additional product content details.

TBD: The Pb-Free/Green conversion plan has not been defined.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that

lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.

Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between

the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight

in homogeneous material)

⁽³⁾MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
