Description
The TPL5111DDCT is an ultra-low-power system timer designed to significantly enhance battery life in power-constrained embedded applications. By integrating a dedicated power gating feature, this IC allows your system to remain in a complete “power-off” state between duty cycles, effectively eliminating leakage current and standby power draw. It is perfectly suited for IoT sensors, energy-harvesting nodes, and any battery-operated device that requires periodic wake-ups to perform tasks.
With an exceptionally low power consumption of just 35nA (typical), the TPL5111 operates continuously while keeping the rest of your system off until the timer expires. Once the pre-set interval is reached, the TPL5111 powers up the host microcontroller or sensor, manages the operation, and subsequently cuts power again. This duty-cycling efficiency makes it a vital component for extending the service life of devices deployed in remote or inaccessible locations.
Key Features
- Integrated Power Gating: Automatically disconnects power from the load between wake-up intervals, maximizing energy savings.
- Ultra-Low Power: Operates at an incredibly low 35nA (typical), ensuring minimal impact on battery budget.
- Efficient Duty-Cycling: Ideal for managing periodic sensor readings or data transmission tasks.
- System Reliability: Provides consistent, precise wake-up intervals for system synchronization.
- Compact Packaging: Housed in a space-saving 6-pin SMD package, perfect for miniaturized electronics.
- Simple Implementation: Designed for easy integration to handle the power-on/power-off sequencing of a host MCU.
Applications
- IoT Wireless Sensor Nodes: Extends battery life by keeping hardware powered off between reporting intervals.
- Energy Harvesting: Manages system activity based on available energy cycles.
- Remote Data Logging: Enables long-term, autonomous operation for field-deployed measurement devices.
- Battery-Operated Electronics: A versatile solution for any project needing automated, low-power duty-cycling.
