System timers cut power consumption by up to 80%
A new family of system timers, designed to significantly extend the lifetime of battery powered and energy harvesting devices, has been unveiled by Texas Instruments.

The TPL5000 with watchdog timer and TPL5100 with MOS driver draw only 30nA of current, a reduction of 90% compared to competitive solutions.
They also replace a microcontroller's internal timer, allowing the mcu to remain in low power sleep mode.
As a result, TI says the programmable devices allow designers to achieve system standby power savings of up to 80% over existing solutions.
