The BQ25120AYFPT is an integrated circuit (IC) component designed by Texas Instruments. It is a highly efficient, ultra-low power management IC specifically developed for use in applications with low-power energy harvesting sources.
Key Features:
1. Ultra-Low Power Consumption: The BQ25120AYFPT is designed to operate with minimal power consumption, making it ideal for energy harvesting applications. It features an ultra-low quiescent current of less than 700 nA, which enables it to maximize power harvested from sources such as solar cells or thermoelectric generators.
2. Multiple Power Management Functions: This IC offers various power management functions in a single device, helping designers simplify their circuits and reduce overall system cost. It includes a highly efficient buck converter, a battery charger, an LDO voltage regulator, and a power supervisor.
3. Integrated Battery Charger: The BQ25120AYFPT integrates a linear battery charger suitable for single-cell lithium-ion (Li-Ion) or lithium-polymer (Li-Po) battery chemistries. It supports a charge current up to 250 mA, helping to efficiently charge the connected battery.
4. Load Switch and LDO Regulator: It also features a load switch with up to 250 mA current capability, which enables the efficient management of system loads. Additionally, a low dropout voltage (LDO) regulator provides a stable supply voltage to power other system components
