TPL5010

The TPL5010 is a highly integrated, low-power timer and power management device designed for battery-powered applications requiring precise control over system wake-up and sleep cycles. It operates with a supply voltage range from 1.8 V to 5.5 V, making it suitable for various portable electronics such as IoT sensors, wearables, and remote monitoring systems. The device features a programmable timeout period ranging from 1 second to 32.768 seconds, allowing flexible configuration based on application needs. At its core, the TPL5010 includes an internal 32 kHz oscillator that ensures accurate timing without relying on external components, reducing both cost and board space. It offers two operating modes: active mode and deep sleep mode. In active mode, the device consumes minimal quiescent current (typically 1.2 µA), while in deep sleep mode, the current drops to less than 1 µA, significantly extending battery life. This ultra-low power consumption makes it ideal for energy-sensitive applications where long operational life is critical. The TPL5010 also provides a dedicated wake-up input (WAKEIN) that allows external events—such as sensor triggers or button presses—to interrupt the timer and activate the system immediately. This feature enables event-driven operation, further optimizing power efficiency. Additionally, the device can be configured to generate a reset pulse or a logic-level output upon expiration of the timeout, facilitating seamless integration with microcontrollers and other digital circuits. Its compact 4-pin SOT-23 package enhances ease of use in space-constrained designs. The TPL5010 supports both manual restart via the WAKEIN pin and automatic restart after timeout, offering versatility in system design. No external resistors or capacitors are required for basic timing functions, simplifying implementation and minimizing component count. Designed for reliability in harsh environments, the TPL5010 includes built-in protection against supply voltage spikes and thermal shutdown mechanisms. Its robust architecture ensures consistent performance across varying temperature ranges (-40°C to +125°C), making it suitable for industrial, automotive, and consumer-grade applications alike.
