BQ25173DSGR Description

Short technical summary and product information.

The BQ25173DSGR from Texas Instruments is an integrated 800mA linear charger specifically designed for 1 to 4-cell supercapacitors, making it suitable for space-constrained designs.

 

This device supports charging supercapacitors from 0V and features an input voltage tolerance of up to 40V, with a maximum operating input voltage of 18V. The charge current is programmable from 10mA to 800mA via an external resistor, and the charge voltage accuracy is ±1%, with charge current accuracy at ±10%. It supports a maximum battery pack voltage of 10.5V.

 

Key features include automatic sleep mode with low leakage current (350nA), external resistor programmability for charge voltage and current, and integrated fault protection including overcurrent, overvoltage, and short-circuit protection. Thermal regulation is active at 125°C, with thermal shutdown at 150°C.

 

The BQ25173DSGR is available in an 8-WSON (2x2 mm) package, suitable for surface mounting. Its applications include smart meters, barcode scanners, portable medical equipment, and dashboard cameras.
