Texas Instruments introduced five new next-generation power management integrated circuits.
Henceforth official, these new next-generation power management integrated
circuits represent another milestone for Texas Instruments, its capacity to
bring innovation where it required.
Connectikpeople can observe that:
·
The new range can acquire and
manage microwatts (uW) to milliwatts (mW) of power harvested from light, heat
or mechanical energy sources.
·
The bq25570, bq25505,
TPS62740, TPS62737 and TPS62736 maintain the industry's lowest levels of active
quiescent current and enable battery-free operation to wireless sensor
networks, monitoring systems, wearable medical
devices, mobile accessories and
other applications with limited access to power.
Regarding the Nano-power harvesting,
According to Texas Instruments,
its new bq25570 boosts charger with integrated buck converter consumes a miniscule 488 nanoamps (nA) of quiescent current and achieves greater than 90-percent efficiency at output currents lower than 10 microamps (uA), maintaining high efficiency even at the lowest amount of available power. The device features maximum power point tracking (MPPT) to extract and manage power from photovoltaic cells and thermoelectric generators, and supports any energy storage element, such as a rechargeable Li-Ion battery, thin film battery, super-capacitor or conventional capacitor. During long periods of storage, power to the bq25570 can be disabled through a "ship mode" feature, which allows the device to consume less than 5 nA.

The bq25505 boost charger is similar to the bq25570, but achieves an even lower active
quiescent current of 325 nA. The bq25505 brings an autonomous power multiplexor
gate drive that enables seamless system operation from energy harvesting
sources and the primary battery, ensuring constant power is available when the
system needs to operate, even when no energy is available from the harvester.
Connectikpeople has also captured the TPS62740, one of the smallest and lowest power buck converters for 300-mA output
current designs.
