3 Description

The TPL5110-Q1 Nano Timer is a low power, AEC- Q100 qualified timer with an integrated MOSFET driver ideal for power gating in duty cycled or battery powered applications. Consuming only 35nA, the TPL5110-Q1 can enable the power supply line and drastically reduce the overall system stand by current during the sleep time. Such power savings enable the use of significantly smaller batteries making it well suited for energy harvesting or wireless sensor applications. The TPL5110-Q1 provides selectable timing intervals from 100ms to 7200s and is designed for power gating applications. In addition, the TPL5110-Q1 has a unique One-shot feature where the timer will only power the MOSFET for one cycle. The TPL5110-Q1 is available in a 6-pin SOT23 package.

8 Detailed Description

8.1 Overview

The TPL5110-Q1 is a timer with power gating feature. It is ideal for use in power-cycled applications and provides selectable timing from 100ms to 7200s. Once configured in timer mode (EN/ONE_SHOT= HIGH) the TPL5110-Q1 periodically sends out a DRV signal to a MOSFET to turn on the µC. If the µC replies with a DONE signal within the programmed time interval (tDRV) the TPL5110-Q1 turns off the µC, otherwise the TPL5110-Q1 keeps the µC in the on state for a time equal to tDRV. The TPL5110-Q1 can work also in a one shot mode (EN/ONE_SHOT= LOW). In this mode the DRV signal is sent out just one time at the power on of the TPL5110-Q1 to turn on the µC. If the µC replies with a DONE signal within the programmed time interval (tDRV) the TPL5110-Q1 turns off the µC, otherwise the TPL5110-Q1 keeps the µC in the on state for a time equal to tDRV.

8.2 Functional Block Diagram

8.3 Feature Description

The TPL5110-Q1 implements a periodical power gating feature or one shot power gating according to the EN/ONE_SHOT voltage. A manual MOSFET Power ON function is realized by momentarily pulling the DELAY/M_DRV pin to VDD.

8.3.1 DRV

The gate of the MOSFET is connected to the DRV pin. When DRV= LOW, the MOSFET is turned ON. The pulse generated at DRV is equal to the selected time interval period, minus 50ms. It is shorter in the case of a DONE signal received from the µC. If the DONE signal is not received within the programmed time interval (minus 50ms), the DRV signal will be high for the last 50ms of the time interval in order to turn off the MOSFET before the next cycle starts. The default value (after resistance reading) is HIGH. The signal is sent out from the TPL5110-Q1 when the programmed time interval starts. When the DRV is LOW, the manual power ON signal is ignored.

8.3.2 DONE

The DONE pin is driven by a µC to signal that the µC is working properly. The TPL5110-Q1 recognizes a valid DONE signal as a low to high transition; if two or more DONE signals are received within the time interval, only the first DONE signal is processed. The minimum DONE signal pulse length is 100ns. When the TPL5110-Q1 receives the DONE signal it asserts DRV logic HIGH.

The current drawn from the supply voltage during the manual power ON is given by VDD/REXT. Figure 14. Manual MOSFET Power ON with SPDT Switch

8.5.3 Selection of the External Resistance

  • T is the desired time interval in seconds.
  • REXT is the resistance value to use in Ω.
  • a,b,c are coefficients depending on the range of the time interval.

8.5.4 Quantization Error

8.5.5 Error Due to Real External Resistance

are characterized by a certain tolerance. This tolerance will affect the accuracy of the time interval.

  1. Evaluate the min and max values of REXT (REXT_MIN, REXT_MAX with Equation 1 using the selected commercial

resistance values and their tolerances.

  1. Evaluate the time intervals (TADC_MIN[REXT_MIN], TADC_MAX[REXT_MAX]) with Equation 4.
  2. Find the errors using Equation 3 with TADC_MIN, TADC_MAX.

The results of the formula indicate the accuracy of the time interval. The example below illustrates the procedure.

  • Desired time interval , T_desired = 600s,

  • Required REXT, from Equation 1, REXT= 57.44kΩ. From Table 4 REXT can be built with a parallel combination of two commercial values with 1% tolerance: R1=107kΩ, R2=124kΩ. The uncertainty of the equivalent parallel resistance can be found using: (6) Where uRn (n=1,2) represent the uncertainty of a resistance, (7) The uncertainty of the parallel resistance is 0.82%, meaning the value of REXT may range between REXT_MIN = 56.96 kΩ and REXT_MAX = 57.90 kΩ. Using these value of REXT, the digitized timer intervals calculated with Equation 4 are respectively TADC_MIN = due to the quadratic transfer function of the resistance digitizer.
