TPL5000
- Supply Voltage from1.8 V to 5.0 V
- Current Consumption 30 nA (typical, at 2.5 V)
- Watchdog Functionality
- Reset Functionality
- Selectable Timer Intervals 1 to 64 s
The TPL5000 is a long-term timer IC optimized for low-power applications. The TPL5000 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 second to 64 seconds. Some standards (such as EN50271) require implementation of a watchdog function for safety. The TPL5000 realizes this watchdog function without consuming additional power. The TPL5000 can also monitor a battery management IC via a power-good digital input and reset the microcontroller, if necessary. The device is packaged in a 10-pin VSSOP package.

TPL5000EVM — 具有看門狗功能的極低功率可程式編輯計時器評估模組
The Texas Instruments TPL5000EVM evaluation module (EVM) allows a designer to configure the 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 (...)
