BQ500100 Description

Short technical summary and product information.

The BQ500100 from Texas Instruments is a voltage output, current-shunt monitor specifically designed for wireless charging systems to enable foreign object detection (FOD). This device is capable of sensing voltage drops across shunts within a wide common-mode voltage range of 0 V to 20 V, independent of the supply voltage.

Key electrical specifications include a fixed voltage gain of 50 V/V with a maximum gain error of 2% and a maximum input offset voltage of ±150 µV. The device operates from a single 2.7-V to 6-V power supply, drawing a maximum quiescent current of 0.115 mA. Its bandwidth is 80 kHz, and it features a slew rate of 0.4 V/µs.

The BQ500100 is specified for operation across a temperature range of -40°C to +105°C. It is supplied in a compact SC70 package, measuring 4.2 mm² with dimensions of 2 mm × 2.1 mm, making it suitable for space-constrained designs.

This current monitor is ideal for applications requiring precise current sensing in wireless power transfer systems, contributing to enhanced safety and performance through effective foreign object detection.
