RESET Defined With Input Voltages as Low as During power-on, RESET is asserted when the 0.4 V supply voltage DD becomes higher than 0.4 Power-On Reset Generator With a Delay Time Thereafter, the supervisory circuit monitors V DD and of 130 ms keeps the RESET output active as long as V DD Push/Pull or Open-Drain RESET Outputs remains below the threshold voltage IT An internal timer delays the return of the output to the inactive SOT23-6 Package state to ensure proper system reset. The delay time Package Temperature Range: C to +85 C starts after V DD has risen above V IT When V DD drops below V IT the output becomes active again.

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.

When RESET is active, triggered by the voltage monitored at V DD the quiescent current increases to about μ A (see the Electrical Characteristics In some period. This is especially true when the voltage of a battery is supervised and the RESET is used to shut down the system or for an early warning. In this case the reset condition will last for a longer period of time. The current drawn from the battery should almost be zero, especially when the battery is discharged. For this kind of application, either the TPS3103 or TPS3106 is a good fit. To minimize current consumption, select a version where the threshold voltage is lower than the voltage monitored at V DD The TPS3106 has two reset outputs. One output RSTVDD is triggered from the voltage monitored at V DD The other output RSTSENSE is triggered from the voltage monitored at SENSE. In the application shown in Figure the TPS3106E09 is used to monitor the input voltage of two NiCd or NiMH cells. The threshold voltage (TH) 0.86 was chosen as low as possible to ensure that the supply voltage is always higher than the threshold voltage at V DD The voltage of the battery is monitored using the SENSE input. The voltage divider was calculated to assert a reset using the RSTSENSE output at 0.8 V 1.6 where: V TRIP is the voltage of the battery at which a reset is asserted and V IT(S) is the threshold voltage at SENSE 0.551 was chosen for a resistor current in the μ A range.

www.ti.com WATCHDOG MANUAL RESET MR PFI, PFO SENSE TPS3103xxx TPS3106xxx TPS3110xxx SLVS363E AUGUST 2001 REVISED SEPTEMBER 2007 The TPS3110 device integrates a watchdog timer that must be periodically triggered by a positive or negative transition of WDI. When the supervising system fails to retrigger the watchdog circuit within the time-out interval, RESET becomes active for the time period D This event also reinitializes the watchdog timer. Many μ C-based products require manual-reset capability, allowing an operator or logic circuitry to initiate a reset. Logic low at MR asserts reset. Reset remains asserted while MR is low and for a time period D after MR returns high. The input has an internal 100-k Ω pull-up resistor, so it can be left open if it is unused. Connect a normally open momentary switch from MR to GND to create a manual reset function. External debounce is not required. If MR is driven from long cables or if the device is used in noisy environments, connecting a 0.1- μ F capacitor from MR to GND provides additional noise immunity. If there is a possibility of transient or DC conditions causing MR to rise above V DD a diode should be used to limit MR to a diode drop above V DD The TPS3103 has an integrated power-fail (PFI) comparator with a separate open-drain PFO output. The PFI and PFO can be used for low-battery detection, power-fail warning, or for monitoring a power supply other than the main supply, and has no effect on RESET An additional comparator is provided to monitor voltages other than the nominal supply voltage. The power-fail input (PFI) will be compared with an internal voltage reference of 0.551 If the input voltage falls below the power-fail threshold IT (S) the power-fail output PFO goes low. If it goes above 0.551 V plus approximately 15-mV hysteresis, the output returns to high. By connecting two external resistors, it is possible to supervise any voltage above 0.551 The sum of both resistors should be approximately M Ω to minimize power consumption and to assure that the current into the PFI pin can be neglected, compared with the current through the resistor network. The tolerance of the external resistors should be not more than to ensure minimal variation of sensed voltage. If the power-fail comparator is unused, connect PFI to GND and leave PFO unconnected. For proper operation of the PFI-comparator, the supply voltage DD must be higher than 0.8 The voltage at the SENSE input is compared with a reference voltage of 0.551 If the voltage at SENSE falls below the sense-threshold IT (S) reset is asserted. On the TPS3106, a dedicated RSTSENSE output is available. On the TPS3110, the logic signal from SENSE is OR-wired with the logic signal from V DD or MR An internal timer delays the return of the output to the inactive state, once the voltage at SENSE goes above 0.551 V plus about mV of hysteresis. For proper operation of the SENSE-comparator, the supply voltage must be higher than 0.8 Submit Documentation Feedback Copyright 2001 2007, Texas Instruments Incorporated

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (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.
