The TPL5100 is a long-term timer IC optimized for low-power applications. The TPL5100 can replace a microcontroller's internal timer, allowing the microcontroller to stay completely off instead of running a timer, providing a total power consumption reduction of 60 to 80%.The TPL5100 is designed for use in power cycled applications and provides selectable timing from 16 seconds to 1024 seconds. The TPL5100 can also monitor a battery management IC via a power-good digital input and power on the microcontroller only when a good supply voltage is present. The device is packaged in a 10-pin VSSOP package.

For all available packages, see the orderable addendum at the end of the datasheet.
