Lead-acid charge controller with full fault protection
The MAX17702ATG+ is a single-cell lead-acid battery charge controller from Analog Devices, designed for constant-current charging with programmable current, timer, and voltage setpoints. It accepts a battery pack voltage from 1.25V to 21.9V, covering 1 to 4 series lead-acid cells (2V, 4V, 6V, 8V, or 12V nominal packs). The 60V maximum supply voltage gives headroom for 12V and 24V automotive systems, surviving load-dump transients without external clamping. Integrated fault protection covers overcurrent, overtemperature, overvoltage, and short-circuit conditions — the full safety set for an unattended charging station.
Temperature grade and package fit
The -40°C to +125°C operating temperature range qualifies the part for under-hood automotive or outdoor enclosure deployment without derating. Housed in a 24-WFQFN exposed pad package measuring 4x4mm, the thermal pad must be soldered to a copper pour on the PCB for heat sinking — the supplier device package is 24-TQFN-EP. Surface-mount mounting type requires a standard reflow soldering profile; the exposed pad is the primary thermal path to the board.
Active lifecycle and compliance
ROHS3 compliant with no lead exemptions, making it suitable for EU and global markets without restricted-substance restrictions. Sourced to order against the BOM quantity; availability and current pricing confirmed at RFQ through independent and authorized distribution channels.
