TPL5000
SNAS628B –JULY 2013–REVISED DECEMBER 2014
TPL5000 Nano-Power Programmable Timer with Watchdog Functionality
1 Features 3 Description
The TPL5000 is a long-term timer IC optimized for
1
• Supply Voltage from1.8 V to 5.0 V
low-power applications. The TPL5000 can replace a
• Current Consumption 30 nA (typical, at 2.5 V)
micro controller's (µC) internal timer, allowing the µC
• Watchdog Functionality
to stay in low-power sleep mode instead of running a
timer, providing a total power consumption reduction
• Reset Functionality
of 60 to 80%. The TPL5000 is designed for use in
• Selectable Timer Intervals 1 to 64 s
interrupt-driven applications and provides selectable
timing from 1 second to 64 seconds. Some standards
2 Applications
(such as EN50271) require implementation of a
watchdog function for safety. The TPL5000 realizes
• Battery-Powered Systems
this watchdog function without consuming additional
• Energy-Harvesting Systems
power. The TPL5000 can also monitor a battery
• Remote Data-Logger
management IC via a power-good digital input and
• Sensor Node
reset the microcontroller, if necessary. The device is
packaged in a 10-pin VSSOP package.
