Evaluation Module for TPL5000 Nano Power Programmable Timer with Watchdog Functionality
The TPL5000EVM is an evaluation module for TPL5000 device. The TPL5000 is a long term timer IC optimized for low power applications. This IC can replace a micro controller's (µC) internal timer, allowing the µC to stay in low power sleep mode instead of running a timer, providing a total power consumption reduction of 60 to 80%. The TPL5000 is designed for use in interrupt driven applications and provides selectable timing from 1 to 64 seconds. Some standards (i. e. EN50271) require implementation of a watchdog function for safety. The TPL5000 realizes this watchdog function without consuming additional power. It can also monitor a battery management IC via a power good digital input and reset the µC if necessary. The evaluation module allows a designer to configure delay timers of the TPL5000 and measure its very low current consumption. Moreover the TPL5000EVM is ready to be connected to the Launchpads of MSP430, Stellaris and C2000 in order to test its watchdog and timer features.
