ADP5092ACPZ-1-R7
Analog Devices Inc.
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.Applications Photovoltaic (PV) cell energy harvesting Thermoelectric generators (TEGs) energy harvesting Industrial monitoring Self powered wireless sensor devices Portable and wearable devices with energy harvesting

AD8280WASTZ-RL
Analog Devices Inc.
The AD8280 is a hardware-only safety monitor for lithium ionbattery stacks. The device has inputs to monitor six battery cellsand two temperature sensors (either NTC or PTC thermistors).The device is designed to be daisy-chained with additional AD8280devices to monitor a stack of significantly more than six cellswithout the need for numerous isolators. The output can beconfigured for an independent or shared alarm state.The AD8280 functions independently from a primarymonitor and contains a reference and LDO, both of which arepowered completely from the battery cell stack. The reference, inconjunction with external resistor dividers, establishes trip pointsfor the overvoltages and undervoltages. Each cell channel containsprogrammable deglitching circuitry to prevent alarms fromtransient input levels.The AD8280 also has two digital pins that can select variouscombinations of inputs in the case where fewer than six cells areto be monitored. Most important, it has a self-test feature, makingit suitable for high reliability applications, such as automotivehybrid electric vehicles or higher voltage industrial usage, such asuninterruptible power supplies. The AD8280 can function over atemperature range of −40°C to +105°C. Applications Lithium ion battery backup monitor and threshold detection Electric and hybrid electric vehicle Industrial vehicle Uninterruptible power supply Wind and solar

ADP5061ACBZ-2-R7
Analog Devices Inc.
The ADP5061 charger is fully compliant with USB 3.0 and the USB Battery Charging Specification 1.2 and enables charging via the mini USB VBUS pin from a wall charger, car charger, or USB host port.The ADP5061 operates from a 4 V to 6.7 V input voltage range but is tolerant of voltages up to 20 V. The 20 V voltage tolerance alleviates the concerns about the USB bus spiking during disconnect or connect scenarios.The ADP5061 features an internal FET between the linear charger output and the battery. This permits battery isolation and, hence, system powering under a dead battery or no batteryscenario, which allows for immediate system function on connection to a USB power supply.Based on the type of USB source, which is detected by an external USB detection chip, the ADP5061 can be set to apply the correct current limit for optimal charging and USB compliance.The ADP5061 has three factory programmable digital input/output pins that provide maximum flexibility for different systems. These digital input/output pins permit combinations of features such as, input current limits, charging enable and disable, charging current limits, and a dedicated interrupt output pin.
