STMicroelectronics SPV1050 IC’s

The SPV1050 is an ultra-low-power energy harvester and battery charger with embedded

MPPT and LDOs. Its main features are:

•

Thermoelectric generators and PV modules energy harvester

•

High efficiency for all harvesting sources, PV cells and TEG.

•

Up to 70 mA maximum battery current

•

Fully integrated buck-boost DC-DC converter 2.5 V to 5.3 V

•

Trimmable battery charge voltage level (± 1% accuracy) 2.1 V to 3.6 V

•

Trimmable battery discharge voltage level (± 1% accuracy)

•

Two fully independent LDOs (1.8 V and 3.3 V output)

•

Enable/disable LDO control pins

•

Battery disconnect function for battery protection

•

Battery connected and ongoing charge logic open drain indication pins

•

Programmable MPPT by external resistors

STMicroelectronics EFL700A39 evaluation boards

Two boards have been developed for training and supporting the design of the solid state

thin film battery EnFilm™ EFL700A39.

The Evaluation kit (Order Number: EFL700EVALKIT) allows to discover the operation of the

EFL700A39 and to monitor the voltage and the dynamic charge /discharge current in real

use-case condition.

The power management board (order number: EFL700PMB) is rather a design-in board

including all the necessary power management circuit around the EFL700A39 and can be

directly connected and used in the application for a fast evaluation.
