BQ25046DQCR Description

Short technical summary and product information.

The BQ25046DQCR is a specialized power management IC from Texas Instruments, designed for both wired and wireless power applications. This IC features a 1.1A maximum charge current and operates with an input voltage range of 3.3V to 9V, with an absolute maximum rating of 30V.

 

Key features include an integrated 3.3V Low Dropout Linear Regulator (LDO) capable of supplying 15mA, which can power companion ICs like the MSP430BQ1010. It also incorporates IC thermal regulation for protection and an integrated pass FET that functions as a load disconnect switch and a 5V regulator. The device supports standalone control with RC-settable interface and operates within a temperature range of -40°C to 85°C.

 

Packaged in a compact 10-WSON (3x2 mm) or 10-WFDFN exposed pad, the BQ25046DQCR is suitable for space-constrained designs. Its applications include handheld and mobile devices, where efficient wireless power solutions up to 5W are required. The device also provides status indications for Power Good (PG) and Output Enabled (CHG).

 

This IC is designed for ease of integration, reducing component count and board space. It offers pin-selectable current limits of 100mA and 400mA, enhancing communication robustness in wireless power systems. A soft-start feature is included to minimize inrush current.
