Introduces a technology that harvests ambient mechanical, thermal or electromagnetic energy from the sensor’s local environment, eliminating the need for batteries in wireless sensors
The document introduces the LTC3588-1, an integrated piezoelectric energy harvesting power supply designed to eliminate the need for replaceable batteries in wireless sensor networks. It addresses the challenge of managing microwatts of ambient mechanical, thermal, or electromagnetic energy from a local environment.
| Application | Piezoelectric energy harvesting power supply |
|---|---|
| Input Current (UVLO) | less than a microamp |
It converts ambient mechanical, thermal, or electromagnetic energy from the sensor's local environment into electrical energy.
It accumulates energy during a low quiescent current phase and releases it to the load in short power bursts.
The undervoltage lockout (UVLO) mode allows charge to build up on an input capacitor until the internal buck converter can efficiently transfer a portion of the stored charge to the output.
