Product details

Package and mounting — 10-LGA land-grid array

The MAX31329ELB+ comes in a 10-pin LGA package (5x5 mm body, supplier device package 10-LGA). It is a surface-mount land-grid array — no leads, just pads on the bottom. The board footprint is compact, but rework requires a hot-air station or reflow oven; hand-soldering is not practical. The -40°C to 85°C operating temperature covers industrial environments: outdoor telecom cabinets, factory-floor PLCs, and HVAC controllers.

Lifecycle and sourcing

The MAX31329ELB+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is listed. No direct second-source or pin-compatible alternate is listed in the official cross-reference.

Frequently asked questions

Is MAX31329ELB+ compatible with 3.3V systems?

Yes, the supply voltage range of 1.6V to 5.5V covers 3.3V and 1.8V rails directly, so no level shifter is needed for the I2C bus if the host microcontroller runs at the same voltage.

Does MAX31329ELB+ have a trickle charger?

Yes, the part includes a trickle charger feature for charging a backup battery or supercapacitor when main power is present.
