LTC6811HG-1 - 12-Cell Battery Monitor with isoSPI | ADI
The Analog Devices LTC6811HG-1#PBF is a 12-channel multicell battery stack monitor housed in a 48-lead SSOP (G) package, designed to measure cell voltages in series-connected battery packs. The device performs 16-bit delta-sigma analog-to-digital conversions on up to 12 series-connected cells with total measurement error below 1.2 mV, supports daisy-chain isolation via the isoSPI two-wire interface, and operates directly from the battery stack. The 'H' temperature grade variant is rated from -40C to +125C and the '-1 G designation selects daisy-chain SPI communication for multi-device stacks. What is a multicell battery monitor? It is a mixed-signal analog front-end (AFE) integrated circuit that measures individual cell voltages in a series battery stack, performs balancing decisions, and reports state-of-charge data to a host controller. Battery monitors belong to the broader category of battery management ICs (BMICs), which sit within the power management semiconductor hierarchy. Modern electric-vehicle and grid-storage battery packs require per-cell monitoring for safety, balancing, and capacity tracking - a task that discrete ADCs cannot reliably perform because of high common-mode voltages, ground-shift hazards, and noise-coupling issues that arise across many cells in series. Key features include 12 cell-voltage measurement channels plus two auxiliary ADC inputs, a built-in 5V LDO regulator for internal biasing, programmable passive cell-balancing outputs (S1-S12), passive or active balancing modes, and an on-chip digital filter for noise rejection. The isoSPI interface provides transformer-isolated communication up to 1 Mbit/s over a single twisted pair, eliminating costly digital isolators in stack-to-host links. The IC supports both PCB-trace and discrete-transformer isolation. Architecturally, the LTC6811 uses a fourth-generation silicon-on-insulator (SOI) high-voltage CMOS process that tolerates common-mode voltages up to 75V per cell and up to several hundred volts across the stack. The integrated delta-sigma modulator provides simultaneous 50 Hz to 5 kHz noise rejection, allowing accurate measurements even in the presence of switching-converter EMI from chargers and inverters. Typical applications include hybrid and pure electric vehicle battery management, grid-tied energy storage systems (ESS), uninterruptible power supplies (UPS), e-mobility scooters and bicycles, telecom 48V battery backup, and large-format lithium-ion or LiFePO4 battery packs. The wide common-mode range and isolated daisy-chain interface make the LTC6811-1 particularly suited to high-voltage (>400V) packs where multiple devices must be chained without PCB ground noise coupling. When designing with the LTC6811-1, carefully size the cell-input RC filters (typically 100 ohm / 10 nF) to balance noise rejection against measurement settling time, and provide adequate thermal copper for the SSOP exposed pad. Use the LTC6811-2 (parallel SPI variant) only for low-channel-count systems where daisy-chain latency would be unacceptable.

The Analog Devices LTC6811IG-1 (LTC6811IG-1#PBF) is a 12-channel multicell battery stack monitor IC housed in a 48-pin SSOP (IG) package with exposed pad, designed for high-voltage battery management systems in electric vehicles, energy storage, and industrial backup. It measures up to 12 series-connected battery cells with a total measurement error below 1.2 mV and supports input common-mode voltages up to 5V per cell, allowing the part to be powered directly from the battery stack. The device integrates a daisy-chain isoSPI interface for galvanically isolated communication, with a single twisted pair carrying data and clock across up to 1000V of stack voltage. A battery monitor IC (also called a multicell battery monitor or cell monitor) is an analog front-end that digitizes the voltage of every cell in a series stack, performs balance-current control, and reports measurements to a host MCU through a digital interface. Battery monitors sit inside the Battery Management System (BMS) hierarchy, alongside cell-balancing ICs and supervisors, and are essential for safety, state-of-charge estimation, and state-of-health tracking in Li-ion, LiFePO4, lead-acid, and supercapacitor packs. Key features of the LTC6811IG-1 include a 12-bit ADC with <1.2 mV total measurement error, onboard passive cell balancing with PWM duty-cycle control per channel, an integrated 5V LDO for housekeeping supply, five general-purpose I/O lines, and a low-power sleep mode that drops quiescent current to 6 µA. Generation-4 silicon also adds improved EMI immunity and faster isoSPI data rates (up to 1 Mbps) over previous-generation LTC6804 parts. The 48-SSOP package with exposed pad offers theta_JA around 40 C/W, suitable for moderate ambient temperatures with a small copper pour. Typical applications include electric-vehicle battery packs (400V and 800V architectures), grid-tied energy-storage systems, telecom backup battery racks, e-mobility scooters and e-bikes, solar battery storage banks, and industrial UPS stacks. The daisy-chain interface means a single BMS host processor can monitor hundreds of cells by chaining multiple LTC6811-1 devices up and down the stack. When designing with this part, always add adequate TVS protection on the cell inputs and provide a low-impedance Kelvin connection at each cell tap to preserve the 1.2 mV accuracy. Use a 10 µF decoupling cap on V+ and place the isoSPI transformer within 50 mm of the LTC6811 pins to meet the 1 Mbps spec.

The -1 suffix denotes the daisy-chain (isoSPI) variant versus the parallel-addressed -2 version. Operating temperature spans -40 C to +85 C for the industrial-grade IG package. Architecturally, the LTC6811 uses a sigma-delta ADC per cell with a precision bandgap reference and on-chip filtering, providing high rejection of common-mode stack noise. The on-board isoSPI transceiver operates at up to 1 Mbps across an isolation barrier using only a twisted pair plus transformer, eliminating the need for an external isolator and CAN/LIN transceivers in many systems. Typical applications include electric-vehicle battery management systems, industrial lithium-ion backup battery monitoring, grid-scale energy storage, e-mobility scooters and bikes, and uninterruptible power supplies. The wide 11 V to 55 V common-mode input range accommodates 8-series to 14-series cell packs directly without additional front-end protection. When designing, ensure the isoSPI cable uses the recommended twisted pair with characteristic impedance near 100 ohm and that a 10 nF bypass capacitor is placed within 5 mm of each supply pin. Note that the LTC6811-1 is pin-compatible and software-compatible with the older LTC6804, simplifying legacy upgrades.

The 1 MHz SPI-compatible isolated daisy-chain interface allows multiple LTC6813-1 devices to be stacked and read over a single transformer-isolated link, supporting packs well beyond 18 cells. The architecture uses a sigma-delta ADC core with on-chip calibration, achieving ±1.5 mV total measurement error across the full temperature range. Built-in noise filters on the cell inputs reject high-frequency switching noise from adjacent DC-DC converters and motor inverters in automotive environments. Typical applications include battery management systems (BMS) for electric vehicles (EV/HEV), energy storage systems (ESS) for solar and grid, industrial uninterruptible power supplies (UPS), e-mobility scooters and forklifts, and any multi-cell Li-ion, LiFePO4, or lead-acid stack requiring precise per-cell monitoring. A key design consideration: when stacking multiple LTC6813-1 parts, the isoSPI link requires a transformer or capacitor isolation barrier; the choice between daisy-chain and parallel-addressing (LTC6813-1 supports both via the '1' variant suffix) materially affects BMS firmware complexity.

A multicell battery monitor is a mixed-signal data-acquisition IC purpose-built for battery management systems (BMS). It sits between the battery stack and the host MCU, translating analog cell voltages into digitized, calibrated values that the MCU uses for state-of-charge, state-of-health, and cell-balancing decisions. Multicell monitors are a subset of battery management ICs, themselves a family of power management semiconductors. The LTC6813-1 is a fourth-generation device from Analog Devices (formerly Linear Technology) and the de-facto reference part for high-cell-count automotive and industrial BMS designs.

A multicell battery monitor is a specialized analog front-end IC that measures the voltage of every cell in a series-connected battery stack and reports the data over an isolation-friendly digital interface. It sits between the raw battery stack (chemistry-agnostic) and the host BMS controller, falling in the hierarchy: cell voltage monitor -> battery management -> power management IC -> mixed-signal semiconductor. Without a monitor IC, the host MCU would need dozens of ADCs, voltage dividers, and protection circuitry. Key differentiating features include a 290 microsecond cell measurement conversion time per ADC cycle, passive cell balancing with programmable PWM duty cycle for each of the 18 channels, an integrated 5V LDO that powers the part from the stack or an isolated supply, and a low-power sleep mode drawing only 6 microamps. The daisy-chain serial interface uses a proprietary differential signaling scheme that crosses the high-voltage isolation barrier with a single transformer or capacitor. At the architectural level, the LTC6813-1 uses a sigma-delta ADC per cell channel with on-chip calibration to achieve the 2.2 mV total measurement error across the full automotive temperature range. The 18 channels share a common-mode range that allows direct connection to battery stacks from 12V up to 1000V when multiple parts are daisy-chained. Internal diagnostics and a watchdog timer support ISO 26262 functional-safety designs. Typical applications include electric vehicle traction battery packs (BEV/PHEV), grid-scale energy storage systems (BESS), hybrid industrial UPS battery banks, e-mobility scooters and motorcycles, and solar-plus-storage residential systems. In each case the LTC6813ILWE-1#3ZZPBF replaces a discrete analog front-end with a calibrated, AEC-Q-aware part. When designing with this device, place 100 nF bypass capacitors on every cell input and a 1 uF low-ESR capacitor on the 5V regulator output, route the daisy-chain traces as 100-ohm differential pairs, and avoid running the isoSPI lines parallel to switching power traces. A typical cell-input RC filter (100 ohm + 10 nF) reduces conducted noise from the pack.

LTM8061IV-8.4#PBF - 32V, 2A Li-Ion Battery Charger µModule | ADI
The Analog Devices LTM8061IV-8.4#PBF is a complete 32V, 2A µModule (power module) standalone Li-Ion/Polymer battery charger optimized for two-cell (8.4V) battery packs, integrating the switching controller, power MOSFETs, inductor, and support components into a single 77-LGA (15mm x 9mm x 4.32mm) over-molded package. It provides fixed 8.4V float voltage, 32V maximum input voltage, and up to 2A programmable charge current, making it a turnkey charging solution for portable and industrial battery-powered systems. A µModule battery charger is a complete switching-mode charger subsystem co-packaged into a single land-grid-array (LGA) module, eliminating the need for discrete power-stage layout. The LTM8061 uses a constant-current/constant-voltage (CC/CV) charge profile, the standard algorithm required by Li-Ion and Li-Polymer cells. As part of the broader power management IC hierarchy (charger IC -> battery management -> PMIC -> semiconductor), it sits between an unregulated DC source (e.g., 5-32V adapter or solar panel) and a 2-cell Li-Ion/Polymer stack. Key features include 32V absolute maximum input voltage, 2A programmable charge current via a single external program resistor, an internal safety timer, auto-restart when battery voltage drops 2.5% below float, NTC input for battery temperature qualification, and a C/10 charge-current termination mode. The µModule construction yields high efficiency, low EMI, and a compact footprint, all critical for space-constrained designs where discrete charger layouts would consume excessive PCB area. The internal architecture combines a current-mode PWM controller, synchronous rectification MOSFETs, an integrated power inductor, and feedback compensation. Built-in input reverse-voltage blocking, output over-voltage protection, and thermal shutdown reduce external component count to just input/output capacitors, program resistor, and the NTC thermistor network. Efficiency peaks above 90% at typical VIN/VOUT ratios due to synchronous rectification. Typical applications include 2-cell Li-Ion/Polymer pack charging in portable medical devices, industrial handheld instruments, two-way radios, power tools, e-bike accessories, and solar-powered IoT sensor nodes. Its 32V VIN tolerance allows direct connection to 12V/24V industrial bus rails or unregulated adapter outputs, removing the need for pre-regulation. When designing with the LTM8061IV-9, allocate at least 1 square inch of PCB copper under the LGA thermal pad to achieve rated 2A charge current; the junction-to-ambient thermal resistance dominates at full power. Use the Analog Devices evaluation board layout as a starting point, and respect the keep-out zone around the LGA package to avoid disturbing the magnetic flux path of the integrated inductor.

A battery charger IC is a power-management device that controls charge current, charge voltage and charge termination for rechargeable cells. The LTM8062 sits at the top of the battery management hierarchy (battery charger -> battery management IC -> power management IC) and integrates a complete switching charger system, including the power switch, power inductor and control loop, inside a single LGA package. This system-in-package approach drastically reduces external component count compared to a controller-plus-discrete-FET design. Key features include a wide 4.95V to 32V input range (40V absolute maximum), 2A maximum charge current, and a precision 0.75% float voltage reference. The device accommodates Li-Ion/Polymer, LiFePO4 and SLA batteries, supports up to 5 cells, and includes integrated input reverse-voltage protection. Resistor-programmable float voltage reaches 14.4V on the LTM8062 (18.8V on the LTM8062A variant). Technically, the LTM8062 employs an input supply voltage regulation loop that reduces charge current whenever the input voltage falls below a resistor-programmed threshold. When powered from a solar panel, this loop performs MPPT (maximum peak power tracking), holding the panel at its peak output power point. The charger also provides preconditioning trickle charge and bad battery detection, improving safety and battery lifetime. Typical applications include solar-powered battery charging systems, portable instrumentation, backup power supplies, and industrial equipment using 12V lead-acid or multi-cell Li-Ion packs. The 32V input range comfortably supports 12V to 24V solar panels and industrial DC buses. Design consideration: because the charger dissipates heat inside the 15 x 9 mm LGA substrate, PCB copper area under the package governs the maximum internal junction temperature; the E-grade version is specified over an internal operating range extending to 125C, but thermal derating of charge current is required at high input-to-output differentials.

MAX14606EWL+T - 36V OVP Protector 54mΩ WLP-9 | Maxim Integrated
The Maxim Integrated (Analog Devices) MAX14606EWL+T is a 36V overvoltage protection (OVP) IC with reverse bias blocking, housed in a 9-bump 1.29 mm × 1.29 mm WLP package. It features a 54 mΩ (typical) internal FET RON, supports an input operating range of 2.3 V to 36 V, and protects downstream low-voltage systems against voltage faults up to +36 V on the IN pin. An OVP protector is a specialized power-path protection IC that sits between a system input (such as a USB-C VBUS, charger, or hot-swap supply) and the downstream DC-DC converter or battery charger. When VIN exceeds the user-programmed overvoltage threshold, the internal MOSFET turns off within microseconds, isolating the load from the fault. The MAX14606 is part of the broader OVP IC family within Maxim's Battery Management portfolio, sitting hierarchically as OVP IC → load switch → power-path protection → power management IC → semiconductor. Compared with discrete P-FET protection schemes, an OVP IC integrates the FET, threshold detection, and thermal protection into one part. Key features include: ±50 mΩ RON typical (path loss reduction at high load current), automatic internal trip threshold selection (eliminates external resistor divider), thermal-shutdown protection against overcurrent events, reverse bias blocking (when disabled, OUT does not feed back into IN), and a CB pin for the protected downstream rail. The 9-bump WLP occupies 1.29 mm × 1.29 mm of PCB area, enabling compact designs in smartphones, wearables, and IoT modules where board real estate is critical. The MAX14606/MAX14607 family uses an integrated N-channel MOSFET architecture with internal charge-pump drive and precision bandgap-based threshold comparators. The reverse-bias blocking feature is unique to this Maxim family: when the device is disabled (CB asserted), current cannot flow backward from OUT to IN, preventing parasitic charging through the body diode of the protection FET. Thermal shutdown engages at approximately +150 °C junction temperature. Typical applications include smartphone USB charging port protection, wearable device VBUS rails, IoT sensor node power inputs, hot-swap supplies up to 36 V, and battery charger front-end protection in portable electronics. The wide 2.3 V to 36 V input range suits both 5 V USB and 12 V/24 V industrial bus systems. A key design consideration is that the MAX14606 and MAX14607 differ only in their default overvoltage threshold — confirm your application requires the MAX14606's specific trip level before substituting. The exposed-die WLP package requires careful PCB pad design and underfill consideration in high-vibration environments.

MAX17262REWL+T - 5.2µA 1-Cell Fuel Gauge with ModelGauge m5 | ADI
The Analog Devices (formerly Maxim Integrated) MAX17262REWL+T is an ultra-low-power 1-cell fuel-gauge IC implementing the proprietary ModelGauge m5 EZ algorithm, supporting both LiFePO4 and Li-ion battery chemistries in a compact 9-pin WLP (1.47 mm × 1.45 mm) package. Headline parameters include 5.2 µA quiescent current, internal current sensing (no external sense resistor required), and best-in-class accuracy for battery capacities from 30 mAhr to 6 Ahr. What is a fuel-gauge IC? A fuel-gauge IC is a battery-management semiconductor that continuously estimates remaining state-of-charge (SOC), state-of-health (SOH), time-to-empty, and runtime for a rechargeable cell. It belongs to the broader hierarchy of battery management ICs → power management ICs → analog mixed-signal semiconductors. The MAX17262 family specifically uses ModelGauge m5 EZ, which combines the short-term accuracy of a coulomb counter with the long-term stability of a voltage-based ModelGauge algorithm, while eliminating battery characterization requirements through EZ configuration. Key features include ±1% SOC accuracy over the full operating range, I2C/SMBus-compatible interface, on-chip temperature sensing, and built-in battery insertion detection. The internal current sense eliminates the bulky external sense resistor that older coulomb-counter designs required, reducing BOM cost and PCB area while improving noise immunity. The device also includes SHA-256 authentication support for battery-pack security applications requiring anti-counterfeit protection. Technically, the MAX17262 samples battery voltage, current, and temperature at a low duty cycle to minimize quiescent current to 5.2 µA, enabling extended shelf life and runtime in always-on battery applications. The ModelGauge m5 algorithm fuses periodic OCV (open-circuit-voltage) measurements with continuous coulomb-count tracking, providing accurate SOC reporting even during high-dynamic-load conditions where pure coulomb counters drift or pure voltage-based gauges become unreliable. Typical applications include wearables (smartwatches, fitness bands, hearables), IoT sensor nodes, Bluetooth trackers, TWS earbuds charging cases, single-cell medical devices, and ultra-thin portable electronics where PCB real estate is constrained. The 9-WLP package occupies only 2.13 mm², making it suitable for the smallest form-factor designs. When designing with the MAX17262, pay attention to PCB layout for the WLP package — the WLP requires NSMD pads and a clean ground plane under the die for accurate temperature sensing. The I2C lines require 4.7 kΩ pull-ups to the host logic level, and the BAT pin must connect to the cell positive terminal through a low-impedance trace.

The 64-pin LQFP-10x10 package gives a manageable thermal resistance while leaving enough perimeter I/O for the 12 HV cell inputs plus digital, analog, and power pins. Architecturally, the part uses a high-voltage CMOS process with on-chip level shifters to tolerate the 60 V-plus common-mode voltage of a 12-cell Li-ion stack. The daisy-chain interface uses capacitive isolation, allowing multiple stacked MAX17823B devices to be daisy-chained and read by a single master MCU through a low-voltage UART. This greatly simplifies the BMS layout in series-string battery packs used in EVs and industrial storage. Typical applications include electric vehicle (EV) battery management systems, hybrid EV pack monitors, industrial lithium-ion energy-storage BMS, e-mobility battery packs (e-bike, e-scooter), and uninterruptible power supply (UPS) battery stacks. The wide operating temperature range and AEC-Q100 qualification also make it suitable for off-road and heavy-machinery battery systems. When designing with this part, ensure the PCB layout keeps the high-voltage cell-input traces physically separated from low-voltage digital/analog signals, and that the daisy-chain isolation capacitors are sized per the datasheet reference design. Compared with discrete solutions using external ADCs and balancing FETs, the MAX17823B significantly reduces PCB area, BOM cost, and firmware complexity.

MAX17843ACB - 12-Ch ASIL-D Battery Monitor IC | 64-LQFP | ADI
The Analog Devices (formerly Maxim Integrated) MAX17843ACB is a 12-channel, high-voltage, ASIL-D-capable smart battery-monitoring data-acquisition interface ASIC, housed in a 64-pin LQFP (10 mm x 10 mm) package and qualified across the -40C to +125C automotive temperature range. It combines a differential 12-channel cell-voltage analog front end (full-scale range up to 5.0 V, usable to 4.8 V per cell), a 14-bit successive-approximation ADC with oversampling, and a high-voltage switch-bank input capable of supporting long series strings of lithium-ion cells used in automotive and energy-storage battery packs. A battery monitor IC (sometimes called a battery management IC, BMIC, or cell-monitoring ASIC) is a mixed-signal device that continuously measures the voltage of every cell in a stacked battery pack and reports the values to a host microcontroller over an isolation-linked serial interface. The MAX17843 family sits at the top of the battery-management hierarchy: cell monitor -> battery monitor ASIC -> BMS host MCU -> pack-level controller -> vehicle or grid-storage system. ASIL-D readiness means the device is designed to support the highest automotive functional-safety integrity level (per ISO 26262) when paired with a system-level safety architecture. Key features include support for long-series cell stacks typically up to 12 series cells, an integrated high-voltage front end that can survive high common-mode pack voltages, integrated diagnostics for open-wire and wire-fault detection, and a digital interface (SPI/UART, per datasheet) suited to daisy-chained or transformer-isolated comms.

Improvements over its predecessor (MAX17823) focus on measurement accuracy and additional safety diagnostics. Designed in a high-voltage BCDMOS process with on-chip level shifting, the MAX17843ACB removes the need for external resistor-divider networks on each cell input and integrates balancing-switch support. The wide 9 V to 65 V (typical) analog supply range covers both 12 V automotive and 48 V mild-hybrid rails. Internally calibrated references and redundancy paths reduce the bill of materials and shrink PCB area in safety-critical battery-management boards. Typical applications include electric-vehicle traction battery packs (BEV/PHEV), 48 V mild-hybrid battery management, e-scooter and e-bike BMS modules, grid-tied residential energy-storage battery stacks, and industrial multi-cell lithium battery packs. It is also used in backup-battery monitoring for telecom and data-center 48 V plants. For long strings (>12S), multiple devices are daisy-chained along the pack height with digital isolation between modules. When laying out the cell-input traces, keep each cell-input differential pair short, symmetric, and routed away from the high-voltage switch-bank node. A dedicated ground plane under the analog section and proper isolation barriers between high-voltage pack nodes and low-voltage logic are required to meet ASIL-D system goals. Per the datasheet, leave adequate creepage on the LQFP-64 footprint, and follow the recommended decoupling network (typically 1 uF + 100 nF close to each supply pin).

Typical applications include personal media players based on the i.MX51 or i.MX37, PND (personal navigation device) platforms using i.MX35, and industrial handheld terminals built on i.MX27. The battery charger function and LED drivers make it especially suitable for battery-powered portable multimedia equipment. A key design consideration: because the MC13892 is a processor-specific PMIC, the power-up sequencing and regulator configuration are tightly coupled to the i.MX boot flow - always verify rail order against the i.MX reference design and program configuration fuses/registers accordingly.
