AD8450ASTZ-RL

Analog Devices Inc.
The AD8450 is a precision analog front end for testing andmonitoring battery cells. Referring to figure one, a precisionprogrammable gain instrumentation amplifier (PGIA)measures the battery’s charge/discharge current and aprogrammable gain difference amplifier (PGDA) measures thebattery’s voltage. Internal laser trimmed resistor networks setthe gains for the PGIA and the PGDA, optimizing the AD8450’sperformance over the rated temperature range. PGIA gains are26×, 66×, 133×, and 200×. PGDA gains are 0.2×, 0.27×,0.4×,and 0.8×.Voltages at the ISET and VSET inputs set the desired constantvoltage (CV) and constant current (CC) values. CC to CVswitching is automatic and transparent to the system.A TTL level logic input, MODE, selects between charge anddischarge modes (high for charge, low for discharge). An analogoutput, VCTRL, interfaces directly with ADI’s ADP1972 &ADP1974 PWM controllers.The AD8450 includes resistor programmable overvoltage andovercurrent detection and current sharing circuitry. Currentsharing is used to balance charge among multiple batteries.The AD8450 simplifies designs by providing excellent accuracy,performance over temperature, flexibility with functionality,and overall reliability in a space-saving package. The AD8450 isavailable in an 80 lead 14 mm ×14 mm × 1 mm LQFP packageand is rated at −40 °C to +85 °C operating temperature.APPLICATIONS Battery cell testing & formation Battery module testing

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.

AD7284WBSWZ

Analog Devices Inc.
The AD7284 contains all the functions required for the general-purpose monitoring of stacked Li-Ion batteries, as used in hybrid electric vehicles and battery backup applications.The AD7284 has multiplexed cell voltage and auxiliary, analog-to-digital converter (ADC) measurement channels supporting four to eight cells of battery management. The device provides a maximum total unadjusted error, TUE, (cell voltage accuracy) of ±3 mV that includes all the internal errors from input to output. The primary ADC resolution is 14 bits.The AD7284 also includes an integrated secondary measurement path that validates the data on the primary ADC. Other diagnostic features include the detection of open inputs, communication, and power supply related faults.The AD7284 cell balancing interface outputs control the external field effect transistors (FETs) to allow discharging of individual cells.There are two on-chip 2.5 V voltage references: one reference for the primary measurement path, and one for the secondary measurement path.The AD7284 operates from one VDD supply, ranging from 10 V to 40 V. The device provides eight differential analog input channels to accommodate large common-mode signals across the full VDD range. Each channel allows an input signal range, VPINx − VPIN(x − 1) and VSINx – VSIN(x − 1), of 0 V to 5 V, where x = 0 to 8. The input pins assume a series stack of eight cells. The AD7284 includes four auxiliary ADC input channels that can be used for temperature measurement or system diagnostics.The AD7284 has a differential daisy-chain interface that allows multiple devices to be stacked without the need for individual device isolation. By design, this interface allows both device to device communication within the same module and communication between devices on different modules.Applications Li-Ion battery monitoring Electric and hybrid electric vehicles Stationary power applications
