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 power up small electronic devices and battery free systems.
The ADP5091/ADP5092 provide efficient conversion of the harvested limited power from a 6 μW to 600 mW range with submicrowatt operation losses. With the internal cold start circuit, the regulator can start operating at an input voltage as low as 380 mV. After cold startup, the regulator is functional at an input voltage range of 0.08 V to 3.3 V. An additional 150 mA regulated output can be programmed by an external resistor divider or the VID pin.
The MPPT control keeps the input voltage ripple in a fixed range to maintain stable dc-to-dc boost conversion. The dynamic sensing mode and no sensing mode, both programming regulation points of the input voltage, allow extraction of the highest possible energy from the harvester. A programmable minimum operation threshold enables boost shutdown during a low input condition.
As a low light indicator for a microprocessor, the LLD pin of the ADP5091 is the MINOP comparator output. However, the REG_GOOD flag of the ADP5092 monitors the REG_OUT voltage. In addition, the DIS_SW pin can temporarily shut down the boost regulator and is RF transmission friendly.
The charging control function of the ADP5091/ADP5092 protects the rechargeable energy storage, which is achieved by monitoring the battery voltage with the programmable charging termination voltage and the shutdown discharging voltage. In addition, a programmable PGOOD flag monitors the SYS voltage.
An optional primary cell battery can be connected and managed by an integrated power path management control block that is programmable to switch the power source from the energy harvester, rechargeable battery, and primary cell battery.
The ADP5091/ADP5092 are available in a 24-lead LFCSP and are rated for a −40°C to +125°C temperature range.
