TPS3820, TPS3823, TPS3824, TPS3825, TPS3828 SLVS165N – APRIL 1998 – REVISED JULY 2022 TPS382x Voltage Monitor With Watchdog Timer 1 Features 3 Description • The TPS382x family of supervisors provide 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 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than 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− + VHYS). 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 TPS382x family also offers watchdog time out options of 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828). • • • • • • 2 Applications • • • • • • • • DSPs, microcontrollers, or microprocessors Industrial equipment Programmable controls Automotive systems Portable and battery-powered equipment Intelligent instruments Wireless communications systems Notebook and desktop computers 3.3 V 100 nF VDD RESET VDD RESET TPS3823-33 WDI MR GND MSP430C325 I/O GND Typical Application Schematic PART NUMBER PACKAGE(1) BODY SIZE (NOM) TPS382x SOT-23 (5) 2.90 mm × 1.60 mm (1) Normalized Input Threshold Voltage −V IT (TA), VIT (25°C) • Power-on reset generator with a fixed delay time of 200 ms (TPS3823, TPS3824, TPS3825, and TPS3828) or 25 ms (TPS3820) Manual reset input (TPS3820, TPS3823, TPS3825, and TPS3828) Reset output available in active-low (TPS3820, TPS3823, TPS3824, and TPS3825), active-high (TPS3824 and TPS3825), and open drain (TPS3828) Supply voltage supervision range: 2.5 V, 3 V, 3.3 V, 5 V Watchdog timer (TPS3820, TPS3823, TPS3824, and TPS3828) Supply current of 15 μA (typical) 5-pin SOT-23 package Temperature range: −40°C to 85°C (−40°C to 125°C for TPS3823A-33) For all available packages, see the orderable addendum at the end of the data sheet. 1.001 1 0.999 0.998 0.997 0.996 0.995 −40 −15 10 35 60 85 TA − Free-Air Temperature − °C Normalized Input Threshold Voltage vs Free-Air Temperature An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.

Optional configurations include devices with active-high and active-low output signals (TPS3824/5), devices with a watchdog timer (TPS3820/3/4/8), and devices with manual reset (MR) pins (TPS3820/3/5/8). RESET asserts when the supply voltage, VDD, rises above 1.1 V. For devices with active-low output logic, the device monitors VDD and keeps RESET low as long as VDD remains below the negative threshold voltage, VIT−. For devices with active-high output logic, RESET remains high as long as VDD remains below 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 rises above the positive threshold voltage (VIT− + VHYS). When the supply voltage drops below VIT−, the output becomes active (low) again. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider, so no external components are required. The TPS382x family is designed to monitor supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The devices are available in a 5-pin SOT-23 package and are characterized for operation over a temperature range of −40°C to 85°C. Only TPS3823A-33 is characterized for operation over a temperature range −40°C to 125°C. 8.2 Functional Block Diagram VDD + _ 52 kW RESET RESET Logic (1) RESET VREF MR (2) Auto-Reset Oscillator 40 kW WDI A.

A low level at MR causes the reset signals to become active. 8.3.2 Active-High or Active-Low Output All TPS382x devices have an active-low logic output (RESET), while the TPS3824/5 devices also include an active-high logic output (RESET). 8.3.3 Push-Pull or Open-Drain Output All TPS382x devices, except for TPS3828, have push-pull outputs. TPS3828 devices have an open-drain output. 14 Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: TPS3820 TPS3823 TPS3824 TPS3825 TPS3828 TPS3820, TPS3823, TPS3824, TPS3825, TPS3828 www.ti.com SLVS165N – APRIL 1998 – REVISED JULY 2022 8.3.4 Watchdog Timer (WDI) The TPS3820, TPS3823, TPS3824, and TPS3828 devices have a watchdog timer that must be periodically triggered by either a positive or negative transition at WDI to avoid a reset signal being issued. 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. The watchdog timer can be disabled by disconnecting the WDI pin from the system. If the WDI pin detects that it is in a high-impedance state, the TPS3820, TPS3823, TPS3824, or TPS3828 will generate its own WDI pulse to ensure that RESET does not assert. If this behavior is not desired, place a 1-kΩ resistor from WDI to ground. This resistor will help ensure that the TPS3820, TPS3823, TPS3824, or TPS3828 detects that WDI is not in a high-impedance state. In applications where the input to the WDI pin is active (transitioning high and low) and the TPS3820, TPS3823, TPS3824, or TPS3828 is asserting RESET, RESET is stuck at a logic low after the input voltage returns above VIT–. If the application requires that input to WDI be active when the reset signal is asserted, then either the A version of the device or a FET should be used to decouple the WDI signal. The A version does not latch the reset signal to the asserted state if a WDI pulse is received while RESET is asserted. An external FET decouples the WDI signal by disconnecting the WDI input when RESET is asserted. For more details on this, see Decoupling WDI During Reset Event. The A version of the device does not require this FET, but it does operate in circuits that have it. Therefore, the A version is backwards-compatible with the non-A versions. 8.4 Device Functional Modes Table 8-1 lists the functional modes of the TPS382x devices. Table 8-1.

TI’s customers are responsible for determining suitability of components for their purposes, as well as validating and testing their design implementation to confirm system functionality. 9.1 Application Information The TPS382x family of devices are very small supervisory circuits that monitor fixed supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The TPS382x family operates from 1.1 V to 5.5 V. Orderable options include versions with either push-pull or open-drain outputs, versions that use active-high or active-low logic for output signals, versions with a manual reset pin, and versions with a watchdog timer. See the Device Comparison Table for an overview of device options. 9.2 Typical Applications 9.2.1 Supply Rail Monitoring With Watchdog Time-Out and 200-ms Delay The TPS3823A can be used to monitor the supply rail for devices such as microcontrollers. The downstream device is enabled by the TPS3823A once the voltage on the supply pin (VDD) is above the internal threshold voltage (VIT– + VHYS). The downstream device is disabled by the TPS3823A when VDD falls below the threshold voltage minus the hysteresis voltage (VIT–). The TPS3823A also issues a reset signal if the WDI input is not 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. Some applications require a shorter reset signal than the 200 ms that most of the TPS382x family provide. In these cases, the TPS3820 is a good choice because it has a delay time of only 25 ms. If an open-drain output is required, replace the TPS3823A with the TPS3828 (if the WDI input must be active while RESET is low, see Decoupling WDI During Reset Event). Figure 9-1 shows the TPS3823A in a typical application. 3.3 V 100 nF VDD RESET VDD RESET TPS3823A-33 WDI MR GND MSP430C325 I/O GND Figure 9-1.
