3 Description

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.
