description

The TPS310x, TPS311x families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSP and processor- based systems. During power on, RESET is asserted when the supply voltage (VDD ) becomes higher than 0.4 V. Thereafter, the supervisory circuit monitors VDD and keeps the RESET output active as long as VDD remains below the threshold voltage (VIT). An internal timer delays the return of the output to the inactive state to ensure proper system reset. The delay time starts after VDD has risen above the VIT. When the VDD drops below the VIT, the output becomes active again. All the devices of this family have a fixed-sense threshold voltage (VIT) set by an internal voltage divider.

The timer clears when reset is asserted or when WDI sees a rising edge or a falling edge. detailed description watchdog 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 (td). This event also reinitializes the watchdog timer. manual reset (MR) Many µC-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 (td) after MR returns high. The input has an internal 100-kΩ 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-µF capacitor from MR to GND provides additional noise immunity. PFI, PFO The TPS3103 has an integrated power-fail (PFI) comparator with a separate open drain (PFO) output can be used for low-battery detection, power-fail warning, or for monitoring a power supply other than the main supply. 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 V. If the input voltage falls below the power-fail threshold (VIT−(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 V. The sum of both resistors should be approximately 1 MΩ, 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 1% 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 (VDD ) must be higher than 0.8 V.

If the voltage at SENSE falls below the sense-threshold (VIT−(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 VDD 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 15 mV of hysteresis. For proper operation of the SENSE-comparator, the supply voltage must be higher than 0.8 V. ABSOLUTE MAXIMUM RATINGS OVER OPERATING FREE-AIR TEMPERATURE (UNLESS OTHERWISE NOTED) (1) (1)Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied.

When RESET, triggered by the voltage monitored at VDD , is active, the quiescent current increases to about 20 µA (see electrical characteristics). In some applications it is necessary to minimize the quiescent current even during the reset 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. Especially when the battery is discharged, the current drawn from the battery should almost be zero. For this kind of applications the TPS3103 or TPS3106 are a good fit. To minimize current consumption it must be assured to 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 VDD . The other output (RSTSENSE) is triggered from the voltage monitored at SENSE. In the application shown in Figure 13, the TPS3106E09 is used to monitor the input voltage of two NiCd or NiMH cells. The threshold voltage (V (th) = 0.86 V) was chosen as low as possible to ensure that the supply voltage is always higher than the threshold voltage at VDD . 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 2 x 0.8 V = 1.6 V. R1 /C0043R2 /C0032/C0466V TRIP V IT(S) /C00421/C0467 Where: VTRIP is the voltage of the battery at which a reset is asserted VIT(S) is the threshold voltage at SENSE = 0.551 V. R1 was chosen for a resistor current in the 1-µA range. With VTRIP = 1.6 V: R1 ≈ 1.9× R2 R1 = 820 k, R2 = 430 k TPS3106E09DBV SENSE GND VDD RSTVDD RSTSENSE
