LTM8062EV#PBF Visão geral
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.

Aplicações típicas
LTM8062EV#PBF é adequado para 6 aplicaçãos: Solar MPPT Battery Charging, Portable and Battery-Powered Instrumentation, Backup Power and UPS Systems, Industrial and Remote Telemetry Equipment, Automotive and Vehicle Auxiliary Power, Security and Surveillance Backup Batteries.
Solar MPPT Battery Charging
The LTM8062EV#PBF is purpose-built for solar charging: its input supply voltage regulation loop reduces charge current whenever the panel voltage drops below a resistor-programmed threshold, effectively holding a 12V or 24V panel at its maximum power point without a separate MPPT controller. The 4.95V to 32V input range (40V abs max) directly accepts typical off-the-shelf solar panels, and the integrated input reverse-voltage protection survives dark-condition panel reversal. In a typical circuit, the module charges a 12V SLA or 3-4 cell Li-Ion pack at up to 2A while the input loop continuously adapts to changing irradiance, maximizing harvested energy across the day. Because the complete charger, switch and inductor are inside the 15 x 9 mm LGA, solar IoT nodes and remote telemetry units gain a compact, low-component-count power stage with bad battery detection for unattended reliability.

Portable and Battery-Powered Instrumentation
Battery-powered field instruments benefit from the LTM8062EV#PBF because a single module handles charging of Li-Ion, Li-Polymer, LiFePO4 or SLA packs with chemically correct termination, eliminating external charge-control circuitry. The 0.75% float voltage reference accuracy prevents overcharging that would shorten lithium cell life, while preconditioning trickle charge safely recovers deeply discharged packs before applying full 2A charge current. Operating from wall adapters or vehicle DC inputs between 4.95V and 32V, the module tolerates widely varying supply quality. The complete charging system integrated in the 77-LGA (15 x 9 mm) package lets handheld instrument designers place the charger on the main PCB without a separate power sub-board, reducing BOM count and assembly cost while the -40C to +125C internal rating covers harsh outdoor measurement environments.
Recomendado
Backup Power and UPS Systems
In standby and backup-power products, the LTM8062EV#PBF maintains 12V SLA batteries at a precise 14.4V-programmed float from a 24V industrial DC bus or a rectified adapter input up to 32V. Bad battery detection periodically verifies pack health, enabling predictive maintenance alerts before a power outage exposes a failed battery. The 2A charge current refills a depleted 7Ah SLA pack in a practical timeframe, and the input voltage regulation loop limits loading on weak or long-cable DC feeds. Because the uModule integrates switching elements, designers avoid the EMI layout effort of discrete charger designs; the LGA substrate and internal magnetics confine high di/dt loops to a few square millimeters. Thermal vias under the package manage the (VIN - VBAT) x ICHARGE dissipation during bulk-charge recovery after an outage.
Recomendado
Industrial and Remote Telemetry Equipment
Remote industrial sensors and telemetry nodes often combine a small solar panel with a lithium or SLA battery, exactly the architecture the LTM8062EV#PBF addresses. Its MPPT input loop extracts peak panel power through wide seasonal irradiance swings, while the wide 4.95V to 32V input accepts 6V to 24V panels without front-end regulation. The -40C to +125C internal operating range survives unheated cabinets and cold-site deployments, and the completely integrated charger stage removes tuning risk from designs that field service technicians must commission without laboratory equipment. Charging LiFePO4 packs, favored in cold climates for cycle life, requires only resistor programming of the float voltage. The tray-packaged, RoHS-compliant 77-LGA module supports standard reflow assembly, keeping production simple for low-to-medium-volume industrial builds.
Recomendado
Automotive and Vehicle Auxiliary Power
Vehicle-mounted equipment charging auxiliary batteries from the 12V or 24V vehicle bus fits the LTM8062EV#PBF input range of 4.95V to 32V, which covers cold-crank and load-dump-adjacent transients within the 40V absolute maximum. The input reverse-voltage protection guards against jump-start misconnection, a frequent field failure mode for discrete charger front ends. Whether maintaining a LiFePO4 starter-support pack or an SLA house battery in trucks, boats, or RVs, the charger's multi-chemistry programming adapts via resistor selection rather than board changes. The 2A charge current suits maintenance and auxiliary batteries up to roughly 20Ah, and trickle preconditioning safely recovers batteries left dormant over winter. Compact 15 x 9 mm LGA integration allows mounting the charger close to the battery within sealed enclosures.

Security and Surveillance Backup Batteries
Wireless security cameras, gate controllers, and NVR backup units require batteries that remain healthy through years of float duty, making the LTM8062EV#PBF's 0.75% float accuracy and correct-chemistry termination valuable. Fed from a 12V or 24V adapter or a small solar panel, the module keeps 12V SLA or 3-cell lithium packs topped up and uses bad battery detection to flag packs degraded by high ambient temperatures typical of outdoor enclosures. The uModule's integrated shielded magnetics limit switching emissions in devices containing sensitive RF links, simplifying coexistence with 2.4GHz radios. At up to 2A charge current, a depleted backup pack recharges within hours, restoring protection quickly after an extended outage. The RoHS-compliant, lead-free (#PBF) construction suits global commercial security deployments.

Notas de projeto
Estimated: charger dissipation is approximately (VIN - VBAT) x ICHARGE plus fixed losses. Charging a 12V battery at 2A from a 24V input gives roughly (24-12)x2 = 24W in bulk phase - substantial heat in a 15x9 mm package. Interleave charge phases (reduce charge current at high VIN-VOUT), use at least 1 square inch of copper plus thermal via arrays under the LGA pad pattern, and verify internal temperature stays within the -40C to +125C envelope per the datasheet thermal derating guidance.
The 77-LGA land pattern requires exact footprint adherence from the Analog Devices datasheet layout package; all 77 pads must connect, including multiple VIN, GND, and sense balls that share current. Place the input and output capacitors within a few millimeters of their balls, and connect BAT sense traces Kelvin-style directly to the battery terminal to preserve the 0.75% float accuracy. The module contains internal magnetics, so no external inductor layout is needed, but keep noisy charger nodes away from precision analog routing.
Do not rely on the LTM8062 reverse-voltage protection as a substitute for proper input polarity design at the connector - it protects the IC but the panel or adapter wiring still matters. Float voltage divider resistors must be 1% or better to hold the programmed 14.4V (or other) setpoint within the 0.75% reference accuracy. For solar designs, set the input regulation threshold slightly below the panel's Vmp so the MPPT loop engages before the panel collapses; if the threshold is set too high, harvested energy drops noticeably at low irradiance.
