TPL5010/TPL5110 Ultra-Low-Power Timers

TI's nano timer with power gating (TPL5010), or with MOS driver and MOSFET power ON (TPL5110)

Image of Texas Instruments TPL5010/TPL5110 Ultra-Low-Power Timers Texas Instruments' TPL5010 nano timer is a low-power timer with a watchdog feature ideal for system wake up in duty cycled or battery powered applications. In such systems the µC timer can be used for system wake-up, but if the timer sleep current is high, up to 60% to 80% of the total system current can be consumed by the µC timer in this sleep mode. Consuming only 35 nA, the TPL5010 can replace the functionality of the integrated μC timer and allow the µC to be placed in a much lower-power mode. Such power savings enable the use of significantly smaller batteries making it well suited for energy harvesting or wireless sensor applications. The TPL5010 provides selectable timing intervals from 100 ms to 7200 s and is designed for interrupt-driven applications. Some standards (such as EN50271) require implementation of a watchdog for safety and the TPL5010 realizes this watchdog function at almost no additional power consumption.

The TPL5110 nano timer is a low-power timer with an integrated MOSFET driver ideal for power gating in duty cycled or battery powered applications. Consuming only 35 nA, the TPL5110 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 provides selectable timing intervals from 100 ms to 7200 s and is designed for power gating applications. In addition, the TPL5110 has a unique one-shot feature where the timer will only power the MOSFET for one cycle.
