description

The TPS382x family of supervisors provides circuit initialization and timing supervision, primarily for DSP and processor-based systems.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

During power-on, RESET is asserted when supply voltage VDD becomes higher than 1.1 V. Thereafter, the supply voltage supervisor 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, 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. 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, ttout, RESET becomes active for the time period td. This event 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.

Figure 1 The product spectrum is designed for supply voltages 3.3 V, and 5 V. The circuits are available 5-pin SOT23-5 package. The TPS382x-xxQ-Q1 devices are characterized for operation over a temperature range to 125°C, and are qualified in accordance with AEC-Q100 stress test qualification for integrated circuits.
