Product details

The MAX77651BEWVA+T is a single-cell Lithium-Ion/Polymer battery charger IC from Analog Devices, designed for space-constrained portable devices. Control is via an I²C interface alongside GPIO pins, allowing the host microcontroller to adjust charge current and voltage dynamically. An integrated over-temperature fault protection shuts down the charger if the die temperature exceeds the safe limit.

Package and board integration

Housed in a 30-bump WLP (Wafer-Level Package) measuring 2.75 mm x 2.15 mm with a 0.4 mm pitch, this IC is suited for compact PCBs where every square millimeter counts. The surface-mount package requires a solder reflow profile compatible with lead-free assembly.

Frequently asked questions

What is the maximum charge current for MAX77651BEWVA+T?

The maximum programmable charge current is 300 mA, constant-current type, for a single Li-Ion or Li-Polymer cell. The charge voltage can be set up to 4.6 V maximum.

What interface does the MAX77651BEWVA+T use for control?

It uses an I²C serial interface along with GPIO pins. The charge current and voltage are programmable through the I²C bus.

What package is the MAX77651BEWVA+T available in?

It comes in a 30-bump WLP (Wafer-Level Package) with dimensions 2.75 mm x 2.15 mm, supplier device package 30-WLP. It is surface-mount only.
