Product details

What the 1.5A charge current and 16V input mean for your BOM

The 16V max supply covers USB and common 5V wall adapters with margin for transients — no need for an external pre-regulator on most portable designs. The constant-current charge is programmable via an external resistor, and the timer is also programmable. That means you set the charge rate and safety timeout to match your battery capacity without firmware intervention.

Industrial temperature grade and fault protection

The integrated fault protection covers over-temperature, reverse current, and short circuit — the chip shuts itself down before the battery or the board sees damage.

Frequently asked questions

What battery chemistries does the BQ24032ARHLT support?

It supports Lithium Ion and Lithium Polymer chemistries, single-cell configuration with a 4.2V battery pack voltage. That covers the vast majority of portable and handheld designs.

What is the charge current limit for the BQ24032ARHLT?

The maximum charge current is 1.5A, and it is programmable via an external resistor. The timer is also programmable, so you can tailor the charge profile to the battery capacity without additional logic.
