  • TPL5110  - The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.   Wider programmable delay range (100 ms to 7200 s), ultra-low power system timer


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.


  • Supply Voltage from 1.8 V to 5.0 V
