SBVS105 – SEPTEMBER 2009 Quad Supply Voltage Supervisors with Programmable Delay and Watchdog Timer Check for Samples: TPS386000 TPS386020 TPS386040 TPS386060 FEATURES DESCRIPTION • • • • • • • The TPS3860x0 family of voltage supervisors can monitor four power rails that are greater than 0.4V with a 0.25% (typical) threshold accuracy. Each of the four supervisory circuits (SVS-n) assert a RESETn or RESETn output signal when the SENSEm input voltage drops below the programmed threshold. With external resistors, the threshold of each SVS-n can be programmed (where n = 1, 2, 3, 4 and m = 1, 2, 3, 4L, 4H). 1 2 • • • • • • • 4 Complete SVS Modules on 1 Silicon Platform Programmable Delay Time: 1.4ms to 10s Very Low Quiescent Current: 12μA typ Threshold Accuracy: 0.25% typ Adjustable Threshold Down to 0.4V SVS-1: Manual Reset (MR) Input SVS-4: Window Comparator or Low-Voltage Sensing with VREF (1.2V) Pin Watchdog Timer with Dedicated Output Well-Controlled RESETn Output During Power-Up TPS386000: Open-Drain RESETn and WDO TPS386020: Open-Drain RESETn and WDO TPS386040: Push-Pull RESETn and WDO TPS386060: Push-Pull RESETn and WDO Package: 4mm x 4mm, 20-pin QFN Each SVS-n has a programmable delay before releasing RESETn or RESETn, and the delay time can be set from 1.4ms to 10s through the CTn pin connection. Only SVS-1 has an active-low manual reset (MR) input; a logic-low input to MR asserts RESET1 or RESET1. SVS-4 monitors the threshold window using two comparators. The extra comparator can be configured as a fifth SVS to monitor negative voltage with voltage reference output VREF. The TPS3860x0 has a very low quiescent current of 12μA (typical) and is available in a small, 4mm x 4mm, QFN-20 package.

GENERAL DESCRIPTION The TPS3860x0 multi-channel supervisory device family combines four complete SVS function sets into one IC. The design of each SVS channel is based on the single-channel supervisory device series, TPS3808. The TPS3860x0 is designed to assert RESETn or RESETn signals, as shown in Table 1, Table 2, Table 3, and Table 4. The RESETn or RESETn outputs remain asserted during a user-configurable delay time after the event of reset release (see the Reset Delay Time section). Each SENSEm (m = 1, 2, 3, 4L, 4H) pin can be set to any voltage threshold above 0.4V using an external resistor divider. A broad range of voltage threshold and reset delay time adjustments can be supported, allowing these devices to be used in a wide array of applications. Table 1.

Pull-up resistors must be used to hold these lines high when RESETn is not asserted, or when RESETn is asserted. By connecting pull-up resistors to the proper voltage rails (up to 6.5V), RESETn or RESETn output nodes can be connected to the other devices at the correct interface voltage levels. The pull-up resistor should be no smaller than 10kΩ because of the safe operation of the output transistors. By using wired-OR logic, any combination of RESETn can be merged into one logic signal. The TPS386040 and TPS386060 provide push-pull reset outputs. The logic high level of the outputs is determined by the VCC voltage. With this configuration, pull-up resistors are not required and some board area can be saved. However, all the interface logic levels should be examined. All RESETn or RESETn connections must be compatible with the VCC logic level. The RESETn or RESETn outputs are defined for VCC voltage higher than 0.9V. To ensure that the target processor(s) are properly reset, the VCC supply input should be fed by the available power rail as early as possible in application circuits. Table 1, Table 2, Table 3, and Table 4 are truth tables that describe how the outputs are asserted or released. Figure 28, Figure 29, Figure 30, and Figure 31 show the SVS-n timing diagrams. When the condition(s) are met, the device changes the state of SVS-n from asserted to released after a user-configurable delay time. However, the transitions from released-state to asserted-state are performed almost immediately with minimal propagation delay. Figure 30 describes relationship between threshold voltages (VITN and VHYSN) and SENSEm voltage; and all SVS-1, SVS-2, SVS-3, and SVS-4 have the same behavior of Figure 30. 16 Submit Documentation Feedback 0.9V t SENSE1 VHYSN VITN t MR t RESET1 tD tD t NOTE: The TPS386000 or TPS386040 is shown here using RESETn.

SBVS105 – SEPTEMBER 2009 SENSE INPUT WINDOW COMPARATOR The SENSEm inputs are pins that allow any system voltages to be monitored. If the voltage at the SENSE1, SENSE2, SENSE3, or SENSE4L pins drops below VITN, then the corresponding reset outputs are asserted. If the voltage at the SENSE4H pin exceeds VITP, then RESET4 or RESET4 is asserted. The comparators have a built-in hysteresis to ensure smooth reset output assertions and deassertions. Although not required in most cases, for extremely noise applications, it is good analog design practice to place a 1nF to 10nF bypass capacitor at the SENSEm input in order to reduce sensitivity to transients, layout parasitics, and interference between power rails monitored by this device. A typical connection of resistor dividers are shown in Figure 33. All the SENSEm pins can be used to monitor voltage rails down to 0.4V. Threshold voltages can be calculated by following equations: The comparator at the SENSE4H pin has the opposite comparison polarity to the other SENSEm pins. In the configuration shown in Figure 33, this comparator monitors overvoltage of the VCC4 node; combined with the comparator at SENSE4L, SVS-4 forms a window comparator. NEGATIVE VOLTAGE SENSING By using voltage reference output VREF, the SVS-4 comparator can monitor negative voltage or positive voltage lower than 0.4V. Figure 1 shows this usage in an application circuit. SVS-4 monitors the positive and negative voltage power rail (for example, +15V and –15V supply to an op amp) and the RESET4 or RESET4 output status continues to be as described in Table 4. Note that RS42H is located at higher voltage position than RS42L. The threshold voltage calculations are shown in the following equations: VCC1_target = (1 + RS1H/RS1L) × 0.4 (V) VCC2_target = (1 + RS2H/RS2L) × 0.4 (V) VCC3_target = (1 + RS3H/RS3L) × 0.4 (V) VCC4_target1 = {1+ RS4H/(RS4M + RS4L)} × 0.4 (V) VCC4_target2 = {1+ (RS4H + RS4M)/RS4L} × 0.4 (V) VCC41_target = (1 + RS41H/RS41L) × 0.4 (V) VCC42_target = (1 + RS42L/RS42H) × 0.4 – RS42L/RS42H × VREF = 0.4 – RS42L/RS42H × 0.8 (V) Where VCC4_target1 is the undervoltage threshold, and VCC4_target2 is the overvoltage threshold.

Table 6 describes the delay time settings. Table 6. Delay Timing Selection CTn CONNECTION DELAY TIME Pull-up to VCC 300ms (typ) Open 20 ms (typ) Capacitor to GND Programmable To select the 300ms fixed delay time, the CTn pin should be pulled up to VCC using a resistor from 40kΩ to 200kΩ. Please note that there is a pulldown transistor from CTn to GND that turns on every time the device powers on to determine and confirm CTn pin status; therefore, a direct connection of CTn to VCC causes a large current flow. To select the 20ms fixed delay time, the CTn pin should be left open. To program a user-defined adjustable delay time, an external capacitor must be connected between CTn and GND. The adjustable delay time can be calculated by the following equation: CCT (nF) = [tDELAY (ms) – 0.5(ms)] × 0.242 Using this equation, a delay time can be set to between 1.4ms to 10s. The external capacitor should be greater than 220pF (nominal) so that the TPS3860x0 can distinguish it from an open CT pin. The reset delay time is determined by the time it takes an on-chip, precision 300nA current source to charge the external capacitor to 1.24V. When the RESETn or RESETn outputs are asserted, the corresponding capacitors are discharged. When the condition to release RESETn or RESETn occurs, the internal current sources are enabled and begin to charge the external capacitors. When the CTn voltage on a capacitor reaches 1.24V, the corresponding RESETn or RESETn pins are released. Note that a low leakage type capacitor (such as ceramic) should be used, and that stray capacitance around this pin may cause errors in the reset delay time. MANUAL RESET The manual reset (MR) input allows external logic signal from other processors, logic circuits, and/or discrete sensors to initiate a device reset. Because MR is connected to SVS-1, the RESET1 or RESET1 pin is intended to be connected to processor(s) as a primary reset source. A logic low at MR causes RESET1 or RESET1 to assert. After MR returns to a 20 Submit Documentation Feedback logic high and SENSE1 is above its reset threshold, RESET1 or RESET1 is released after the user-configured reset delay time. Note that unlike the TPS3808 series, the TPS3860x0 does not integrate an internal pull-up resistor between MR and VCC. To control the MR function from more than one logic signal, the logic signals can be combined by wired-OR into the MR pin using multiple NMOS transistors and one pull-up resistor. WATCHDOG TIMER The TPS3860x0 provides a watchdog timer with a dedicated watchdog error output, WDO or WDO. The WDO or WDO output enables application board designers to easily detect and resolve the hang-up status of a processor. As with MR, the watchdog timer function of the device is also tied to SVS-1. Figure 32 shows the timing diagram of the WDT function. Once RESET1 or RESET1 is released, the internal watchdog timer starts its countdown. Inputting a logic level transition at WDI resets the internal timer count and the timer restarts the countdown. If the TPS3860x0 fails to receive any WDI rising or falling edge within the WDT period, the WDT times out and asserts WDO or WDO. After WDO or WDO is asserted, the device holds the status with the internal latch circuit. To clear this timeout status, a reset assertion of RESET1 or RESET is required. That is, a negative pulse to MR, a SENSE1 voltage less than VITN, or a VCC power-down is required. To reset the processor by WDT timeout, WDO can be combined with RESET1 by using the wired-OR with the TPS386000 option. For legacy applications where the watchdog timer timout causes RESET1 to assert, connect WDO to MR; see Figure 33 for the connections and see Figure 34 and Figure 35 for the timing diagram. This legacy support configuration is available with the TPS386000 and TPS386040. IMMUNITY TO SENSEn VOLTAGE TRANSIENTS The TPS3860x0 is relatively immune to short negative transients on the SENSEn pin. Sensitivity to transients depends on threshold overdrive, as shown in the typical performance graph TPS386040 SENSEn Minimum Pulse Width vs SENSEn Threshold Overdrive Voltage (Figure 12).

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
