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.
