Ultra-low-power system timer for power gating in automotive duty-cycled applications

The Texas Instruments 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 device 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 device provides selectable timing intervals from 100ms to 7200s and is designed for power gating applications. In addition, it has a unique one-shot feature where the timer will only power the MOSFET for one cycle. The device is available in a six-pin SOT23 package.
