The BQ24024DRCR is a single-cell linear charger for Lithium Ion or Polymer batteries, part of the bqTINY™-II family from Texas Instruments. It accepts power from a USB port and delivers a programmable constant current up to 500 mA to the battery, terminating at 4.2 V. The charge current and safety timer are set with external resistors — no I²C or firmware needed.
Texas Instruments has marked the BQ24024DRCR as Last Buy. If this charger is on your BOM, the decision window is now: place a last-time-buy order or qualify a replacement before the cutoff. We can source the BQ24024DRCR against an RFQ — confirm your annual or lifetime volume and we will quote the remaining available inventory and any LTB allocation.
Package and thermal design note
The device comes in a 10-VFDFN with exposed pad, supplier package designation 10-VSON (3x3 mm). Without it, the linear regulator's power dissipation at 500 mA charge current will push the junction temperature above the 125°C limit in a warm ambient.
