Analog Devices ADP5091

Beschreibung

The ADP5091/ADP5092 are intelligent, integrated energy harvesting, ultralow power management unit (PMU) solutions that convert dc power from PV cells or TEGs. These devices charge storage elements such as rechargeable Li-Ion batteries, thin film batteries, super capacitors, or conventional capacitors, and

Eigenschaften

Boost regulator with maximum power point tracking (MPPT) with dynamic sensing or no sensing modeHysteresis mode for best ultralight load efficiencyOperating quiescent current of SYS pin (VIN > VCBP ≥ VMINOP): 510 nASleeping quiescent current of SYS pin (VCBP < VMINOP): 390 nAInput voltage operating range: 0.08 V to 3.3 VFast cold start from 380 mV (typical) with charge pumpProgrammable shutdown point on MINOP pin based on the input open circuit voltage (OCV)150 mA regulated output from 1.5 V to 3.6 VBattery terminal charging threshold (2.2 V to 5.2 V) to support charging storage elementsOptional BACK_UP power path managementRadio frequency (RF) transmission conducive to shutting down the switcher temporarily via microcontroller unit (MCU) communication
