Texas Instruments TPL5x10 Nano-Power System Timers
Texas Instruments TPL5x10 Nano-Power System Timers are low power timers with either a watchdog (TPL5010) or integrated MOSFET driver (TPL5110) feature that is ideal for duty-cycled or battery powered applications. Consuming only 35nA, the TPL5x10 provides power savings that can enable the use of significantly smaller batteries making it well suited for energy harvesting or wireless sensor applications. Each device provides selectable timing intervals from 100ms to 7200s and is designed for interrupt-driven applications.
威尼斯游乐城appTexas Instruments TPL5010 Nano-Power System 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 60-80% of the total system current can be consumed by the µC timer in this sleep mode. Consuming only 35nA, 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 100ms to 7200s 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.

|TPL5010EVM Evaluation ModuleTexas Instruments TPL5010EVM Evaluation Module allows a designer to configure the timer intervals of the TPL5010 and measure its very low current consumption. Moreover, the TPL5010EVM is ready to be connected to the Launchpad of MSP430F5529 in order to test its watchdog and timer features. The EVM has an on-board battery holder (coin battery) to supply the TPL5010 and the microcontroller if connected.FeaturesStandalone EVMBattery powered (optional)Plug / Play into MSP430F5529 launchpadManual configuration of the timer interval View Product Detail|
